How to get input multiple time from a text in android?

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>

Make character count visible during input

I have an EditText used for a description.
Below it, I have a TextView showing the number of characters inputted in the EditText.
Example:
The user should be able to see the live character count during the input, but at this moment the characted counter is hidden by the keyboard:
What can I do to correct that ?
Here is my xml code:
<EditText
android:id="#+id/MyDescription"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#null"
android:maxLength="500"
android:hint="Description" />
<TextView
android:id="#+id/MyDescriptionCharCount"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="0/500"
android:layout_below="#id/MyDescription"
android:layout_marginTop="5dp"
android:layout_marginRight="3dp"
android:layout_marginEnd="3dp"
android:layout_alignParentRight="true"
android:layout_alignParentEnd="true" />
The parent is a RelativeLayout.

You have to extend the class with TextWatcher and override afterTextChanged(),beforeTextChanged(), onTextChanged().
EditText MyDescription = (EditText)findViewById(R.id. MyDescription);
MyDescription.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) {
// s.toString().trim().length();
}
});
You can try the following layout.
<RelativeLayout
android:id="#+id/bottom_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true">
<EditText
android:id="#+id/edit_text"
android:layout_width="match_parent"
android:layout_height="50dp"
android:layout_marginLeft="16dp"
android:background="#android:color/transparent"
android:inputType="textNoSuggestions|textMultiLine"
android:maxLength="200"
android:paddingBottom="8dp"
android:paddingRight="5dp"
android:paddingTop="8dp"
android:textColor="#202020"
android:textColorHint="#979797"
android:textSize="14sp"/>
<TextView
android:id="#+id/charecter_count"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/add_comment_edit_text"
android:layout_gravity="bottom"
android:layout_marginBottom="8dp"
android:layout_marginLeft="16dp"
android:layout_marginTop="8dp"
android:gravity="bottom"
android:text="0/200"
android:textColor="#979797"
android:textSize="14sp"/>
</RelativeLayout>

To see Textview of character counter, add below line in activity tag of manifest file.
android:windowSoftInputMode="adjustResize|stateAlwaysHidden"
This will automatically move your activity layout up to fix in available height after adding soft input keyboard.For more detail about this check here.

Not able to input numbers in autoCompleteTextView android

In this AutoCompleteTextView i am able to enter all alphabets and special characters, just not numbers. Issue is observed on lollipop and above. works fine on kitkat
<AutoCompleteTextView
android:id="#+id/editTextSearchView"
android:layout_width="match_parent"
android:layout_height="60dp"
android:layout_toLeftOf="#+id/searchclear"
android:layout_marginBottom="20dp"
android:layout_marginLeft="16dp"
android:layout_marginTop="10dp"
android:dropDownHeight="160dp"
android:gravity="center_vertical"
android:hint="Enter Location"
android:imeOptions="actionDone"
android:paddingLeft="10dp"
android:paddingStart="10dp"
android:paddingTop="12dp"
android:singleLine="true"
android:textColor="#color/theme_color"
android:textColorHint="#color/theme_color"
android:textCursorDrawable="#null" />
textWatcher used on the edit text box :
autoCompleteTextView.addTextChangedListener(new TextWatcher() {
#Override
public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {
}
#Override
public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {
}
#Override
public void afterTextChanged(Editable editable) {
if(editable.length() > 0)
autoCompleteClearButton.setVisibility(View.VISIBLE);
else
autoCompleteClearButton.setVisibility(View.GONE);
}
});

try using the android:inputType property in the layout file, set it to number or text

add this line in your xml
<AutoCompleteTextView
android:id="#+id/editTextSearchView"
......
android:inputType="number"
.......
...... />

Content from EditText does not appear in TextView.

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!

EditText does not accept numbers Android

I am developing an app for Android and I have a problem with my EditText : I can't write numbers on it. I created a function in order to allow my users to valid an answer in an EditText when they click on "OK" but, with this function, they can't write numbers on my EditTexts.
Here is my function's code :
ed.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) {
}
#Override
public void afterTextChanged(Editable s) {
ed.setOnKeyListener(new View.OnKeyListener() {
#Override
public boolean onKey(View v, int keyCode, KeyEvent event) {
if (keyCode == 66){
if (ed.getText().toString().equals(rep)) {
k++;
if (k == 1) {
Intent ActivityTransition = new Intent(Level6f.this, Transition6.class);
startActivityForResult(ActivityTransition, KEY1);
}
}
else {
ed.getText().clear();
Vibrator vib = (Vibrator) getSystemService(Context.VIBRATOR_SERVICE);
vib.vibrate(50);
}
}
if (keyCode == 67) {
ed.getText().clear();
}
return true;
}
});
}
});
Here my XML EditText's code :
<EditText
android:layout_width="110dp"
android:layout_height="45dp"
android:inputType="textVisiblePassword"
android:id="#+id/editText"
android:textSize="22sp"
android:layout_above="#id/curseur"
android:layout_centerHorizontal="true"/>

I think you can use
android:imeOptions="actionDone"
in your xml instead of android:inputType="textVisiblePassword"

Use this line in your xml (EditText)
android:inputType="number|numberDecimal"
this line allows number and number decimal.
Example -
<EditText
android:layout_width="110dp"
android:layout_height="45dp"
android:inputType="number|numberDecimal|textVisiblePassword"
android:id="#+id/editText"
android:textSize="22sp"
android:layout_above="#id/curseur"
android:layout_centerHorizontal="true"/>

Create your own ok button. Surround editText with a Tablerow and put the ok button in there.
<TableRow
android:id="#+id/tableRow1"
android:layout_width="110dp"
android:layout_height="45dp"
android:layout_above="#id/curseur" >
<EditText
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="1"
android:id="#+id/editText"
android:textSize="22sp"
android:layout_centerHorizontal="true"/>
<Button
android:id="#+id/okbutton"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:text="Ok"
android:textColor="#000000"
android:textSize="22sp"
android:textStyle="bold" />
</TableRow>
