Here is the problem with double hint - TextInputLayout and EditText double hint issue
I need to do the same. I need two hints. One is a title of EditText, and second is a possible value if nothing wasn't input.
But unfortunately there is only one tag:
android:hint
Can I do something with it?
UPD1:
The answer was to set hint for EditText programatically and hint for TextInputLayout in xml.
<android.support.design.widget.TextInputLayout
android:layout_width="match_parent"
android:hint="#string/prompt_quantity"
android:layout_height="wrap_content">
<EditText
android:id="#+id/quantity"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:inputType="number"
android:maxLines="1"
android:singleLine="true" />
</android.support.design.widget.TextInputLayout>
And
quantityEditText.setOnFocusChangeListener(new View.OnFocusChangeListener() {
#Override
public void onFocusChange(View v, boolean hasFocus) {
quantityEditText.setHint(hasFocus ? "0" : "");
}
});
With the Material Components library you can use
android:hint="Label" to add a floating label
app:placeholderText="Placeholder Text" to add a placeholder in the EditText.
Use something like:
<com.google.android.material.textfield.TextInputLayout
android:hint="Label"
app:placeholderText="Placeholder Text"
..>
<com.google.android.material.textfield.TextInputEditText />
</com.google.android.material.textfield.TextInputLayout>
Note: it requires at least the version 1.2.0-alpha03.
Just check your input and change the hint depending on that:
EditText editText = (EditText)findViewById(R.id.editText);
editText.addTextChangedListener(new TextWatcher()
{
#Override
public void afterTextChanged(Editable s)
{
if(editText.getText().toString().equals(""))
editText.setHint("");
else
editText.setHint("Your normal hint");
}
});
Try this way
xml layout
<?xml version="1.0" encoding="utf-8"?>
<merge xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_gravity="center_vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/non_active_edit_text"
android:focusable="false"
android:gravity="right|center_vertical"
android:hint="Right"
android:paddingTop="4dp"
android:background="#null"/>
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/active_edit_text"
android:hint="Left"
android:layout_gravity="center_horizontal"/>
</merge>
JAVA class
public class TwoHints extends RelativeLayout{
EditText activeField;
EditText nonActiveEditText;
final CharSequence hint;
public TwoHints(Context context, AttributeSet attrs) {
super(context, attrs);
LayoutInflater.from(context).inflate(R.layout.two_hints_edit_text, this);
activeField = (EditText)findViewById(R.id.active_edit_text);
nonActiveEditText = (EditText)findViewById(R.id.non_active_edit_text);
hint = nonActiveEditText.getHint();
activeField.addTextChangedListener(new TextWatcher() {
#Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
#Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
nonActiveEditText.setHint(s.length() !=0 ? "" : hint);
}
#Override
public void afterTextChanged(Editable s) {
}
});
}
}
editetext for xml
<you.package.TwoHints

I have a layout where i have 4 circular edittext to enter PIN.
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:orientation="horizontal">
<EditText
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/four_pin_background"
android:inputType="number"
android:textAlignment="center"
android:maxLength="1"
android:imeOptions="actionNext"
android:cursorVisible="false"/>

android:textAlignment="center"

android:background="#drawable/four_pin_background"
android:inputType="number"

</LinearLayout>
I want like after entering number for first edittext, it should automatically move to next edittext.
Now after tapping on next edittext or after tapping on next button from soft keyboard only i am able to enter number.
Can anyone please help me how to do this?
Follow these steps it will give you your desired result :-
Update your XML with ids in EditTexts like this :-
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:orientation="horizontal">
<EditText
android:id ="#+id/firstET"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/four_pin_background"
android:inputType="number"
android:textAlignment="center"
android:maxLength="1"
android:imeOptions="actionNext"
android:cursorVisible="false"/>
<EditText
android:id ="#+id/secondET"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/four_pin_background"
android:inputType="number"
android:textAlignment="center"
android:maxLength="1"
android:imeOptions="actionNext"
android:cursorVisible="false"/>
</LinearLayout>
Then inside your JAVA Code ,
Take Reference of these EditTexts , and add this code inside your onCreate() method of your Activity like :-
EditText firstET , secondET;
firstET = (EditText) findViewByID(R.id.firstET);
secondET = (EditText) findViewByID(R.id. secondET);
firstET.addTextChangedListener(new TextWatcher() {
#Override
public void afterTextChanged(Editable s) {
// TODO Auto-generated method stub
}
#Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
// TODO Auto-generated method stub
}
#Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
// add a condition to check length here - you can give here length according to your requirement to go to next EditTexts.
if(firstET.getText().toString().trim().length() >2){
firstET.clearFocus();
firstET.requestFocus();
}
}
});
Attach a TextWatcher
Check for needed length of editText input and focus next.
editText.addTextChangedListener(new TextWatcher() {
#Override
public void afterTextChanged(Editable s) {
if (s.length() == PIN_LENGTH) {
focusNext();
}
}
});
You need to use addTextChangedListener
Adds a TextWatcher to the list of those whose methods are called whenever this EditText's text changes.
Sample Code
editText.addTextChangedListener(new TextWatcher() {
#Override
public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {
// specify length of your editext here to move on next edittext
if(editText.getText().toString().trim().length()>=1){
NexteditText.requestFocus();
}
}
#Override
public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {
}
#Override
public void afterTextChanged(Editable editable) {
}
});
How can we embed an input text with a TextView in Android?
For example, I want to implement this:
"Your Name is ___ , This is the Level ____"
The "___" is the blank space which the user must fill with a specified input and I'll check it for validation.
Please note that it is different from android:hint.
How can I implement this?
You could make a fill in the blanks type format using constant text inside EditText. Do this by creating an EditText in XML.
<EditText
android:id="#+id/editText"
android:layout_height="wrap_content"
android:layout_width="match_parent"/>
In your Java class add the following code:
final EditText edittext = (EditText) findViewById(R.id.editText);
edittext.setText("Something ");
Selection.setSelection(edittext.getText(), edittext.getText().length());
edittext.addTextChangedListener(new TextWatcher() {
#Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
// TODO Auto-generated method stub
}
#Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
// TODO Auto-generated method stub
}
#Override
public void afterTextChanged(Editable s) { if(!s.toString().contains("Something ")){
edittext.setText("Something ");
Selection.setSelection(edittext.getText(), edittext.getText().length());
}
}
});
This is output of the code. Here the string Something is static and cannot be removed.
You could hide the underline in Edittext using android:background="#android:color/transparent". I would also recommend you to disable enter in the EditText by using the code:
<EditText
android:id="#+id/editText"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:maxLines="1" <----- add this
android:inputType="text"/> <------ and this to disable enter in edittext
You can try like this
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<TextView
android:layout_width="wrap_content"
android:layout_height="30dp"
android:textSize="16sp"
android:textColor="#000000"
android:text="Your Name is"
android:id="#+id/textview1" />
<EditText
android:layout_width="60dp"
android:textSize="16sp"
android:layout_height="40dp"
android:textColor="#000000"
android:id="#+id/edittext1"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="30dp"
android:textSize="16sp"
android:textColor="#000000"
android:text=", This is the Level"
android:id="#+id/textview2" />
<EditText
android:layout_width="60dp"
android:textSize="16sp"
android:layout_height="40dp"
android:textColor="#000000"
android:id="#+id/edittext2"/>
</LinearLayout>
How to add icon hint edittext in center
I have no idea to set that
and in xml file is not have android:drawbleCenter
How to create it
thanks for your help ;)
Unfortunately you can not set drawable at the center of the EditText like this, Alternatively, you can use background image which includes your hint + image what ever you display and inside,
Try below example.
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="15dp"
android:layout_marginRight="15dp"
android:background="#android:drawable/editbox_background"
android:gravity="center">
<EditText
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#null"
android:drawableLeft="#android:drawable/ic_menu_search"
android:gravity="center"
android:hint="Search" />
</RelativeLayout>
You can achieve this type of view using above XML code
Add android:gravity="center_horizontal" to EditText
I have a solution
This is xml:
<FrameLayout
android:layout_width="match_parent"
android:layout_height="50dp">
<EditText
android:id="#+id/edt_search"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<TextView
android:id="#+id/text_icon"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:drawableLeft="#android:drawable/ic_menu_search"
android:drawablePadding="8dp"
android:layout_gravity="center_horizontal"
android:gravity="center_vertical"
android:text="Search"
android:textColor="#969696" />
</FrameLayout>
in onCreate()
edtSearch.addTextChangedListener(new TextWatcher() {
#Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
#Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
textIcon.setVisibility(View.GONE);
}
#Override
public void afterTextChanged(Editable s) {
textIcon.setVisibility(s.length() == 0 ? View.VISIBLE : View.GONE);
}
});
Try it!
I have a customize EditText character with some simple character and image.
Look like this image :
But i want the image padding the bottom like this image :
This is my pwd_bullet.png :
This is my code :
custom_edittext.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#5b5555"
tools:context="com.example.user.myapplication.Custom_Edittext">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#fff">
<EditText
android:layout_width="match_parent"
android:layout_height="60dp"
android:id="#+id/editText"
android:inputType="text"
android:gravity="center_vertical"
android:background="#null"/>
</LinearLayout>
</RelativeLayout>
Custom_Edittext.java
public class Custom_Edittext extends Activity implements TextWatcher{
EditText editText;
Spannable.Factory spannableFactory;
int lastIndex = -1;
protected void onCreate(Bundle savedInstanceState) {
enter code here`super.onCreate(savedInstanceState);
setContentView(R.layout.custom_edittext);
editText = (EditText) findViewById(R.id.editText);
spannableFactory = Spannable.Factory
.getInstance();
editText.addTextChangedListener(this);
}
public Spannable getIconText(Context context, CharSequence text, int index) {
Spannable spannable = spannableFactory.newSpannable(text);
if (index>lastIndex) {
spannable.setSpan(new ImageSpan(context, R.drawable.pwd_bullet),
index, index + 1,
Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
}
lastIndex=index;
return spannable;
}
public void beforeTextChanged(CharSequence s, int start, int count, int after) {}
public void onTextChanged(CharSequence s, int start, int before, int count) {
if (start>4) {
editText.removeTextChangedListener(this);
editText.setText(getIconText(getApplicationContext(), s, start));
editText.addTextChangedListener(this);
editText.setSelection(s.length());
}
}
public void afterTextChanged(Editable s) {}
}
There is no need to use padding in this case, Just use a Linear layout since your items are in a straight line, and make sure you set the Linear layout to an orientation and the gravity as below. This worked for me. Good luck
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center_vertical"
android:orientation="horizontal">
<EditText
android:layout_width="wrap_content"
android:layout_height="60dp"
android:id="#+id/editText"
android:inputType="text"
android:gravity="center_vertical"
android:background="#null"
android:text="Simple Text" />
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/pwd_bullet.png"/>
</LinearLayout>
Create an xml to custom pwd_bullet in drawable
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:id="#+id/layer_list"
android:drawable="#drawable/pwd_bullet"
android:width="10dp"
android:height="10dp"
android:left="3dp"
android:bottom="5dp"/>
</layer-list>
I am completely new in android but I thought I at lease learnt how to write simple code to have contents from EditText appear in the TextView. But seems like not. Can anyone help? Thank you in advance. Here is my code.
detailsActivity.java
public class DetailsActivity extends ActionBarActivity {
EditText etTop;
TextView tvTop;
String cTop;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.details_activity);
//imageUri = Uri.parse(extras.getString("imageUri"));
Bitmap bitmap = getIntent().getParcelableExtra("id");
ImageView imageView = (ImageView) findViewById(R.id.image);
imageView.setImageBitmap(bitmap);
etTop = (EditText) findViewById(R.id.etTop);
tvTop = (TextView) findViewById(R.id.tvBottom);
cTop = etTop.getText().toString();
tvTop.setText(cTop);
}
}
details_activity.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:background="#b72828">
<ImageView
android:id="#+id/image"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scaleType="fitCenter" />
<EditText
android:layout_width="match_parent"
android:layout_height="80dp"
android:id="#+id/etTop"
android:hint="Enter Top Text"
android:textColor="#color/white"
android:clickable="true"
android:gravity="center"
android:inputType="textCapWords"
android:maxLines="2"
android:textColorHint="#fdfdfd"
android:textSize="30dp"
android:textStyle="bold" />
<TextView
android:layout_width="fill_parent"
android:layout_height="30dp"
android:textAppearance="?android:attr/textAppearanceLarge"
android:text=""
android:id="#+id/tvBottom"
android:layout_above="#+id/etBottom"
android:layout_centerHorizontal="true" />
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Create"
android:id="#+id/cButton"
android:layout_gravity="center_horizontal|bottom"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:clickable="false" />
<EditText
android:layout_width="match_parent"
android:layout_height="80dp"
android:id="#+id/etBottom"
android:hint="Enter Bottom Text"
android:textColor="#color/white"
android:layout_gravity="center_horizontal"
android:clickable="true"
android:gravity="center"
android:inputType="textCapWords"
android:maxLines="2"
android:textColorHint="#fdfdfd"
android:textSize="30dp"
android:textStyle="bold"
android:layout_above="#+id/cButton"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true" />
<TextView
android:layout_width="fill_parent"
android:layout_height="30dp"
android:textAppearance="?android:attr/textAppearanceLarge"
android:text=""
android:id="#+id/tvTop"
android:layout_below="#+id/etTop"
android:layout_centerHorizontal="true" />
</RelativeLayout>
Reason:
cTop = etTop.getText().toString();
tvTop.setText(cTop);
gets executed as soon as activity is created. By this time you don't get any chance to enter any text in EditText. When yo do, this code has been already executed. So you need to get the text from EditText and set it into TextView when you actually enter the text.
Solution:
Remove above mentioned two lines of code and add this
etTop.addTextChangedListener(new TextWatcher() {
public void afterTextChanged(Editable s) {
tvTop.setText(s.toString());
}
public void beforeTextChanged(CharSequence s, int start,int count, int after) {}
public void onTextChanged(CharSequence s, int start,int before, int count) {}
});
Now every time you will change the text in EditText, TextView will be update automatically.
try doing this:
etTop.addTextChangedListener(new TextWatcher() {
#Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
#Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
tvTop.setText(s);
}
#Override
public void afterTextChanged(Editable s) {
//.. Or set it here if this is desired behavior
}
});
Your code doesn't listen for changes to the EditText instead your code is saying, go get me the text right now, instead of listening for text being added into the edit text.
So having said that drop these lines:
cTop = etTop.getText().toString();
tvTop.setText(cTop);
and add the above snippet of code in its place.
Good Luck and Happy Coding!
