I am using Material Components for creating the Choice chip. I have followed https://material.io/develop/android/components/chip/ document. There is enough stuff for creating a chip in XML but not get an idea of how to create choice chip programmatically.
I have used following code to creating chip dynamically but it creates action chip by default.
val chip = Chip(activity)
chip.text = ("Chip 1")
chipGpRow.addView(chip)
Check the Mike comment.
Otherwise you can define a simple layout (layout_chip_choice.xml) with the Chip and the style:
<com.google.android.material.chip.Chip
xmlns:android="http://schemas.android.com/apk/res/android"
style="#style/Widget.MaterialComponents.Chip.Choice"
.../>
Then use in your code:
val chip = inflater.inflate(R.layout.layout_chip_choice, chipGpRow, false) as Chip
chip.text = ("Chip 1")
chipGpRow.addView(chip)
following is my code, hope its useful to you :
create item xml for chips and add style that you want
like here style="#style/Widget.MaterialComponents.Chip.Choice"
item_chip_category.xml
<com.google.android.material.chip.Chip xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:fontFamily="#font/popin"
android:gravity="center"
android:paddingLeft="8dp"
android:paddingRight="8dp"
style="#style/Widget.MaterialComponents.Chip.Choice"
android:textAppearance="?android:attr/textAppearance"
android:textColor="#color/secondaryTextColor"
app:chipBackgroundColor="#color/colorAccent" />
activity.xml
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<TextView
android:id="#+id/textView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:fontFamily="#font/popin"
android:padding="8dp"
android:text="Python Progrgrams"
android:textAlignment="center"
android:textAppearance="#style/TextAppearance.AppCompat.Medium"
android:textColor="#color/secondaryTextColor"
android:textStyle="bold" />
<com.google.android.material.chip.ChipGroup
android:id="#+id/chipsPrograms"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="#dimen/text_margin"
android:paddingStart="#dimen/text_margin"
android:paddingEnd="#dimen/text_margin"
app:chipSpacing="8dp"
app:singleSelection="false">
</com.google.android.material.chip.ChipGroup>
</LinearLayout>
Activity.java
public void setCategoryChips(ArrayList<String> categorys) {
for (String category :
categorys) {
Chip mChip = (Chip) this.getLayoutInflater().inflate(R.layout.item_chip_category, null, false);
mChip.setText(category);
int paddingDp = (int) TypedValue.applyDimension(
TypedValue.COMPLEX_UNIT_DIP, 10,
getResources().getDisplayMetrics()
);
mChip.setPadding(paddingDp, 0, paddingDp, 0);
mChip.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton compoundButton, boolean b) {
}
});
chipsPrograms.addView(mChip);
}
}
You could either 1) create an xml layout for a chip that has the choice style and inflate it in code, similar to the ChipGroupDemoFragment example in the catalog: github.com/material-components/material-components-android/blob/… 2) create a custom theme that sets the default chipStyle to be #style/Widget.MaterialComponents.Chip.Choice I recommend #1 because it allows you the flexibility of dynamically creating chips of multiple styles.
XML
<com.google.android.material.chip.ChipGroup
android:id="#+id/chipGroupEmail"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
Activity.java
//init
ChipGroup chipGroupEmail = findViewById(R.id.chipGroupEmail);
//create a function
private void funAddChip(String name) {
Chip chip = new Chip(requireContext());
chip.setText(name);
chip.setCloseIconVisible(true);
chip.setMinWidth(100);
chip.setOnCloseIconClickListener(view -> {
try {
chipGroupEmail.removeView(view);
} catch (Exception e) {
Utils.Log_d("funAddChip Exception:-" + e);
}
});
chipGroupEmail.addView(chip);
}
I don't like the comment on setting the checkable attribute manually instead of the stylistic way. You lose other attributes, like ripple color and state list animator. Inflating a layout with your chip defined and including the style attribute with choice is the only way to do it as of now.
I have been trying to apply a style to a Chip created programmatically with context theme wrapper. This seems like the way to go, but Chip as an extension of AppCompatCheckBox does not define the four-argument constructor where the default style (action) could be overwritten with choice in my case. So the chip is always of type action ><.
This is supposed to be something pretty straight forward but for some reason, the listener for the Checkbox does not work.
Here's my layout :
<RelativeLayout
android:layout_width="match_parent"
android:layout_marginRight="16dp"
android:layout_marginLeft="16dp"
android:layout_height="wrap_content">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="12sp"
android:layout_marginLeft="#dimen/dimen_5"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_centerVertical="true"
android:textStyle="bold"
android:text="#string/my_text"
/>
<CheckBox
android:id="#+id/check_status"
android:layout_width="wrap_content"
android:layout_alignParentRight="true"
android:layout_alignParentEnd="true"
android:layout_height="wrap_content" />
</RelativeLayout>
And here's the implementation in my fragment:
CheckBox checkBox = mView.findViewById(R.id.check_status);
checkBox.setOnCheckedChangeListener(new
CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton buttonView, boolean
isChecked) {
LOGD(TAG, "IsButton checked ? "+ isChecked);
Toast.makeText(getActivity(), "Check",
Toast.LENGTH_SHORT).show();
}
});
Like I said, this is something supposed to be pretty straight forward, but the listener.....well it doesn't listen anything. I'm testing on Nexus 5x Oreo and a small Motorola Marshmallow.
At some point I even tried the setOnClickListener() method:
checkBox.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
LOGD(TAG, "IsButton checked ? "+ ((CheckBox)
v).isChecked());
}
});
The result is the same, I don't see anything in the logcat
Does anyone have a clue as to why the Checkbox's listener is not working properly ?
If you use DataBinding, set the attribute android:checked="#={viewModel.someState}" and later call this listener via ViewBinding like
binding.checkBox.setOnCheckedChangeListener { _, _ ->
//
}
setOnCheckedChangeListener won't be called.
You can set app:checkListener and use BindingAdapter:
#BindingAdapter("app:checkListener")
fun CheckBox.setCheckedChangeListener(listener: CompoundButton.OnCheckedChangeListener) {
setOnCheckedChangeListener(listener)
}
Or observe changes in someState:
viewModel.someState.observe(viewLifecycleOwner) {
viewModel.changeCheckBox()
// Other actions.
}
There are few reason to not works.
In your xml you have to at-lease define checked type as per your requirement.
android:checked="false"
In java file you have to required used setOnCheckedChangeListener().
Hope its work for all.
Most likely, setOnCheckedChangeListener() is not being called :)
Is there a clever way to let the user switch between hide and view password in an android EditText?
A number of PC based apps let the user do this.
It is really easy to achieve since the Support Library v24.2.0.
What you need to do is just:
Add the design library to your dependencies
dependencies {
compile "com.android.support:design:24.2.0"
}
Use TextInputEditText in conjunction with TextInputLayout
<android.support.design.widget.TextInputLayout
android:id="#+id/etPasswordLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:passwordToggleEnabled="true"
android:layout_marginBottom="#dimen/login_spacing_bottom">
<android.support.design.widget.TextInputEditText
android:id="#+id/etPassword"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="#string/fragment_login_password_hint"
android:inputType="textPassword"/>
</android.support.design.widget.TextInputLayout>
The passwordToggleEnabled attribute will do the job!
In your root layout don't forget to add xmlns:app="http://schemas.android.com/apk/res-auto"
You can customize your password toggle by using:
app:passwordToggleDrawable - Drawable to use as the password input visibility toggle icon.
app:passwordToggleTint - Icon to use for the password input visibility toggle.
app:passwordToggleTintMode - Blending mode used to apply the background tint.
More details in TextInputLayout documentation.
For AndroidX
Replace android.support.design.widget.TextInputLayout with com.google.android.material.textfield.TextInputLayout
Replace android.support.design.widget.TextInputEditText with com.google.android.material.textfield.TextInputEditText
You can dynamically change the attributes of a TextView. If you would set the XML Atrribute android:password to true the view would show dots if you set it to false the text is shown.
With the method setTransformationMethod you should be able to change this attributes from code. (Disclaimer: I have not tested if the method still works after the view is displayed. If you encounter problems with that leave me a comment for me to know.)
The full sample code would be
yourTextView.setTransformationMethod(new PasswordTransformationMethod());
to hide the password. To show the password you could set one of the existing transformation methods or implement an empty TransformationMethod that does nothing with the input text.
yourTextView.setTransformationMethod(new DoNothingTransformation());
To show the dots instead of the password set the PasswordTransformationMethod:
yourEditText.setTransformationMethod(new PasswordTransformationMethod());
of course you can set this by default in your edittext element in the xml layout with
android:password
To re-show the readable password, just pass null as transformation method:
yourEditText.setTransformationMethod(null);
To show:
editText.setInputType(InputType.TYPE_TEXT_VARIATION_VISIBLE_PASSWORD);
To hide:
editText.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_VARIATION_PASSWORD);
After each of these the cursor is reset, so:
editText.setSelection(editText.length());
You can use app:passwordToggleEnabled="true"
here is example given below
<android.support.design.widget.TextInputLayout
android:id="#+id/password"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:passwordToggleEnabled="true"
android:textColorHint="#color/colorhint"
android:textColor="#color/colortext">
I had the same issue and it is very easy to implement.
All you have to do is wrap your EditText field in a (com.google.android.material.textfield.TextInputLayout) and in that add ( app:passwordToggleEnabled="true" ).
This will show the eye in the EditText field and when you click on it the password will appear and disappear when clicked again.
<com.google.android.material.textfield.TextInputLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:textColorHint="#B9B8B8"
app:passwordToggleEnabled="true">
<EditText
android:id="#+id/register_password"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="24dp"
android:layout_marginRight="44dp"
android:backgroundTint="#BEBEBE"
android:hint="Password"
android:inputType="textPassword"
android:padding="16dp"
android:textSize="18sp" />
</com.google.android.material.textfield.TextInputLayout>
Use checkbox and change the input type accordingly.
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
int start,end;
Log.i("inside checkbox chnge",""+isChecked);
if(!isChecked){
start=passWordEditText.getSelectionStart();
end=passWordEditText.getSelectionEnd();
passWordEditText.setTransformationMethod(new PasswordTransformationMethod());;
passWordEditText.setSelection(start,end);
}else{
start=passWordEditText.getSelectionStart();
end=passWordEditText.getSelectionEnd();
passWordEditText.setTransformationMethod(null);
passWordEditText.setSelection(start,end);
}
}
private boolean isPasswordVisible;
private TextInputEditText firstEditText;
...
firstEditText = findViewById(R.id.et_first);
...
private void togglePassVisability() {
if (isPasswordVisible) {
String pass = firstEditText.getText().toString();
firstEditText.setTransformationMethod(PasswordTransformationMethod.getInstance());
firstEditText.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_VARIATION_PASSWORD);
firstEditText.setText(pass);
firstEditText.setSelection(pass.length());
} else {
String pass = firstEditText.getText().toString();
firstEditText.setTransformationMethod(HideReturnsTransformationMethod.getInstance());
firstEditText.setInputType(InputType.TYPE_CLASS_TEXT);
firstEditText.setText(pass);
firstEditText.setSelection(pass.length());
}
isPasswordVisible= !isPasswordVisible;
}
At first this is the screen loaded with an image vector asset visibility
on click it will change to this image visibility off

It's work for me.This will help you definitely
showpass.setOnCheckedChangeListener(new OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
if(!isChecked){
// show password
password_login.setTransformationMethod(PasswordTransformationMethod.getInstance());
Log.i("checker", "true");
}
else{
Log.i("checker", "false");
// hide password
password_login.setTransformationMethod(HideReturnsTransformationMethod.getInstance());
}
}
});
I feel I want answer this question even there some good answers ,
according to documentation TransformationMethod do our mission
TransformationMethod
TextView uses TransformationMethods to do things like replacing the
characters of passwords with dots, or keeping the newline characters
from causing line breaks in single-line text fields.
Notice I use butter knife, but its the same if user check show password
#OnCheckedChanged(R.id.showpass)
public void onChecked(boolean checked){
if(checked){
et_password.setTransformationMethod(null);
}else {
et_password.setTransformationMethod(new PasswordTransformationMethod());
}
// cursor reset his position so we need set position to the end of text
et_password.setSelection(et_password.getText().length());
}
I'm able to add the ShowPassword / HidePassword code with just a few lines, self-contained in a block:
protected void onCreate(Bundle savedInstanceState) {
...
etPassword = (EditText)findViewById(R.id.password);
etPassword.setTransformationMethod(new PasswordTransformationMethod()); // Hide password initially
checkBoxShowPwd = (CheckBox)findViewById(R.id.checkBoxShowPwd);
checkBoxShowPwd.setText(getString(R.string.label_show_password)); // Hide initially, but prompting "Show Password"
checkBoxShowPwd.setOnCheckedChangeListener( new CompoundButton.OnCheckedChangeListener() {
public void onCheckedChanged(CompoundButton arg0, boolean isChecked) {
if (isChecked) {
etPassword.setTransformationMethod(null); // Show password when box checked
checkBoxShowPwd.setText(getString(R.string.label_hide_password)); // Prompting "Hide Password"
} else {
etPassword.setTransformationMethod(new PasswordTransformationMethod()); // Hide password when box not checked
checkBoxShowPwd.setText(getString(R.string.label_show_password)); // Prompting "Show Password"
}
}
} );
...
In very simple form:
private fun updatePasswordVisibility(editText: AppCompatEditText) {
if (editText.transformationMethod is PasswordTransformationMethod) {
editText.transformationMethod = null
} else {
editText.transformationMethod = PasswordTransformationMethod()
}
editText.setSelection(editText.length())
}
Hope it helps.
private int passwordNotVisible=1;
#Override
protected void onCreate(Bundle savedInstanceState) {
showPassword = (ImageView) findViewById(R.id.show_password);
showPassword.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
EditText paswword = (EditText) findViewById(R.id.Password);
if (passwordNotVisible == 1) {
paswword.setInputType(InputType.TYPE_TEXT_VARIATION_VISIBLE_PASSWORD);
passwordNotVisible = 0;
} else {
paswword.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_VARIATION_PASSWORD);
passwordNotVisible = 1;
}
paswword.setSelection(paswword.length());
}
});
}
Try https://github.com/maksim88/PasswordEditText project at github.
You dont even need to change your Java code using it. Just change
EditText
tag to
com.maksim88.passwordedittext.PasswordEditText
in your XML file.
You can SHOW/HIDE password using this below code:
XML CODE:
<EditText
android:id="#+id/etPassword"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="21dp"
android:layout_marginTop="14dp"
android:ems="10"
android:inputType="textPassword" >
<requestFocus />
</EditText>
<CheckBox
android:id="#+id/cbShowPwd"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignLeft="#+id/etPassword"
android:layout_below="#+id/etPassword"
android:text="#string/show_pwd" />
JAVA CODE:
EditText mEtPwd;
CheckBox mCbShowPwd;
mEtPwd = (EditText) findViewById(R.id.etPassword);
mCbShowPwd = (CheckBox) findViewById(R.id.cbShowPwd);
mCbShowPwd.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
// checkbox status is changed from uncheck to checked.
if (!isChecked) {
// show password
mEtPwd.setTransformationMethod(PasswordTransformationMethod.getInstance());
} else {
// hide password
mEtPwd.setTransformationMethod(HideReturnsTransformationMethod.getInstance());
}
}
});
Try this:
First define a flag as global like this:
private boolean isShowPassword = false;
And set listener to handle tap on show and hide password button:
imgPassword.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (isShowPassword) {
etPassword.setTransformationMethod(new PasswordTransformationMethod());
imgPassword.setImageDrawable(getResources().getDrawable(R.drawable.ic_eye_hide));
isShowPassword = false;
}else{
etPassword.setTransformationMethod(null);
imgPassword.setImageDrawable(getResources().getDrawable(R.drawable.ic_eye_show));
isShowPassword = true;
}
}
});
show and hide password Edit_Text with check Box

Did you try with setTransformationMethod? It's inherited from TextView and want a TransformationMethod as a parameter.
You can find more about TransformationMethods here.
It also has some cool features, like character replacing.
What I did was to
Create an edit text view and a normal text view
Make them overlap with each other by using constraint layout (just like Facebook app login screen)
Attach an onClickListener to the normal text view so that it changes the input type of the edit text view accordingly (Visible / Non-visible)

According to this source, if you have migrated your project to AndroidX, then you can replace
compile "com.android.support:design:24.2.0"
with
implementation "com.google.android.material:material:1.0.0"
Then all you have to do is to put the code below to your layout file:
<com.google.android.material.textfield.TextInputLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:passwordToggleEnabled="true"
android:hint="#string/hint_text">
<com.google.android.material.textfield.TextInputEditText
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
</com.google.android.material.textfield.TextInputLayout>
More information about material TextInputLayout can be found here.
To this source, it is recommended to migrate to AndroidX from Android Support Library:
AndroidX is the open-source project that the Android team uses to
develop, test, package, version and release libraries within Jetpack.
AndroidX is a major improvement to the original Android Support
Library. Like the Support Library, AndroidX ships separately from the
Android OS and provides backwards-compatibility across Android
releases. AndroidX fully replaces the Support Library by providing
feature parity and new libraries. In addition AndroidX includes the
following features:
All packages in AndroidX live in a consistent namespace starting with
the string androidx. The Support Library packages have been mapped
into corresponding androidx.* packages. For a full mapping of all the
old classes and build artifacts to the new ones, see the Package
Refactoring page.
Unlike the Support Library, AndroidX packages are separately
maintained and updated. The androidx packages use strict Semantic
Versioning starting with version 1.0.0. You can update AndroidX
libraries in your project independently.
All new Support Library development will occur in the AndroidX
library. This includes maintenance of the original Support Library
artifacts and introduction of new Jetpack components.
A good solution. Set up a button, then use this code:
public void showPassword(View v)
{
TextView showHideBtnText = (TextView) findViewById(R.id.textView1);
if(showHideBtnText.getText().toString().equals("Show Password")){
password.setTransformationMethod(null);
showHideBtnText.setText("Hide");
} else{
password.setTransformationMethod(new PasswordTransformationMethod());
showHideBtnText.setText("Show Password");
}
}
1 - Make a selector file "show_password_selector.xml"
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#drawable/pwd_hide"
android:state_selected="true"/>
<item android:drawable="#drawable/pwd_show"
android:state_selected="false" />
</selector>
2 - Aet "show_password_selector" file into imageview.
<ImageView
android:id="#+id/iv_pwd"
android:layout_width="#dimen/_35sdp"
android:layout_height="#dimen/_25sdp"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:layout_marginRight="#dimen/_15sdp"
android:src="#drawable/show_password_selector" />
3 - Put below code in java file.
iv_new_pwd.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (iv_new_pwd.isSelected()) {
iv_new_pwd.setSelected(false);
Log.d("mytag", "in case 1");
edt_new_pwd.setInputType(InputType.TYPE_CLASS_TEXT);
} else {
Log.d("mytag", "in case 1");
iv_new_pwd.setSelected(true);
edt_new_pwd.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_VARIATION_PASSWORD);
}
}
});
You have to ask if the current text is already shown with dots, the function PasswordTransformationMethod.getInstance() allow you to do that.
This is my funtion in kotlin:
fun hideAndShowPassword(editText: EditText, indicator: ImageView) {
if (editText.transformationMethod == PasswordTransformationMethod.getInstance()) {
editText.transformationMethod = HideReturnsTransformationMethod.getInstance()
indicator.setImageDrawable(
ContextCompat.getDrawable(
editText.context,
R.drawable.eye
)
)
indicator.imageTintList =
ContextCompat.getColorStateList(editText.context, R.color.colorTintIcons)
} else {
editText.transformationMethod = PasswordTransformationMethod.getInstance()
indicator.setImageDrawable(
ContextCompat.getDrawable(
editText.context,
R.drawable.eye_off
)
)
indicator.imageTintList =
ContextCompat.getColorStateList(editText.context, R.color.colorTintIcons)
}
editText.setSelection(editText.text.length)
}
It seems that input_layout.isPasswordVisibilityToggleEnabled = true is deprecated. And in my case I did it that way in Kotlin:
input_edit_text.inputType = TYPE_CLASS_TEXT or TYPE_TEXT_VARIATION_PASSWORD
input_layout.endIconMode = END_ICON_PASSWORD_TOGGLE
Where input_edit_text is com.google.android.material.textfield.TextInputEditText and input_layout is com.google.android.material.textfield.TextInputLayout. Of course you should import these asl well:
import android.text.InputType.TYPE_CLASS_TEXT
import android.text.InputType.TYPE_TEXT_VARIATION_PASSWORD
import com.google.android.material.textfield.TextInputLayout.END_ICON_PASSWORD_TOGGLE
My may customize the icon with provided methods as these:
input_layout.endIconDrawable = ...
input_layout.setEndIconOnClickListener { }
input_layout.setEndIconOnLongClickListener(...)
I used a OnClickListener() which is associated to the button that I want to use as toogle.
private EditText email_et, contraseña_et;
protected void onCreate(Bundle savedInstanceState) {
....
contraseña_et = (EditText) findViewById(R.id.contraseña_et);
....
vercontra_btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
int inputType = contraseña_et.getInputType();
if (inputType == 129){
contraseña_et.setInputType(1);
} else {
contraseña_et.setInputType(129);
}
contraseña_et.setSelection(contraseña_et.getText().length());
}
});
Reading docs, the int value seems to be different so I debugged to find the correct values, it's working awesome and is a little bit easier this way.

In XML do like this
<LinearLayout
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:orientation="vertical"
>
<RelativeLayout
android:id="#+id/REFReLayTellFriend"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
>
<EditText
android:id="#+id/etpass1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#android:color/transparent"
android:bottomLeftRadius="10dp"

android:fontFamily="#font/frutiger"
android:gravity="start"
android:inputType="textPassword"
android:hint="#string/regpass_pass1"
android:padding="20dp"
android:paddingBottom="10dp"
android:textColor="#000000"
android:textColorHint="#d3d3d3"
android:textSize="14sp"
android:topLeftRadius="10dp"
android:topRightRadius="10dp"/>
<ImageButton
android:id="#+id/imgshowhide1"
android:layout_width="40dp"
android:layout_height="20dp"
android:layout_marginTop="20dp"
android:layout_marginRight="10dp"

android:layout_alignRight="#+id/etpass1"/>
</RelativeLayout>
boolean show=true;
//on image click inside password do this
if(show){
imgshowhide2.setBackgroundResource(0);
imgshowhide2.setBackgroundResource(R.drawable.hide);
etpass2.setInputType(InputType.TYPE_TEXT_VARIATION_VISIBLE_PASSWORD);
etpass2.setSelection(etpass2.getText().length());
show=false;
}else{
imgshowhide2.setBackgroundResource(0);
imgshowhide2.setBackgroundResource(R.drawable.showpass);
//etpass1.setInputType(InputType.TYPE_TEXT);
etpass2.setInputType(InputType.TYPE_CLASS_TEXT |
InputType.TYPE_TEXT_VARIATION_PASSWORD);
etpass2.setSelection(etpass2.getText().length());
show=true;
}
My Kotlin extension . write once use everywhere
fun EditText.tooglePassWord() {
this.tag = !((this.tag ?: false) as Boolean)
this.inputType = if (this.tag as Boolean)
InputType.TYPE_TEXT_VARIATION_PASSWORD
else
(InputType.TYPE_CLASS_TEXT or InputType.TYPE_TEXT_VARIATION_PASSWORD)
this.setSelection(this.length()) }
You can keep this method in any file and use it everywhere
use it like this
ivShowPassword.click { etPassword.tooglePassWord() }
where ivShowPassword is clicked imageview (eye) and etPassword is Editext
Add this method:
fun EditText.revertTransformation() {
transformationMethod = when(transformationMethod) {
is PasswordTransformationMethod -> SingleLineTransformationMethod.getInstance()
else -> PasswordTransformationMethod.getInstance()
}
}
Call it will switch between input type state (you may change the Single-Line transformation to your favorite). Usage example:
editText.revertTransformation()
