Set unchangeable some part of editText android

Question

I have some EditText for mobile number input. App must add unique text for every country. For example for Armenia is must add +374 , and user must fill other numbers. Also +374 must be unchangeable, user can't change or remove it. So is there some kind of ways for doing this?

EDIT:

I don't want to use textView or another view with this text and put it left of the ediText. I want to find some way with less operations. I need text to be frozen not to check every text changes or add missing text when user will delete some part of it.

Answer 1

Create a custom drawable class that will help to convert text into drawable.

public class TextDrawable extends Drawable {    private final String text;   private final Paint paint;    public TextDrawable(String text) {       this.text = text;       this.paint = new Paint();       paint.setColor(Color.BLACK);       paint.setTextSize(16f);       paint.setAntiAlias(true);       paint.setTextAlign(Paint.Align.LEFT);   }    @Override   public void draw(Canvas canvas) {       canvas.drawText(text, 0, 6, paint);   }    @Override   public void setAlpha(int alpha) {       paint.setAlpha(alpha);   }    @Override   public void setColorFilter(ColorFilter cf) {       paint.setColorFilter(cf);   }    @Override   public int getOpacity() {       return PixelFormat.TRANSLUCENT;   } } 

Then set the drawable to left of the edittext as

EditText et = (EditText)findViewById(R.id.editText1); String code = "+374"; et.setCompoundDrawablesWithIntrinsicBounds(new TextDrawable(code), null, null, null); et.setCompoundDrawablePadding(code.length()*10); 

Where the edittext is defined in the layout file as

<EditText android:id="@+id/editText1" android:layout_width="fill_parent" android:layout_height="wrap_content" android:textSize="16sp" android:ems="10" >   <requestFocus /> </EditText> 

Final Output looks like

public class MainActivity extends Activity {  private EditText editText;  @Override protected void onCreate(Bundle savedInstanceState) {     super.onCreate(savedInstanceState);     setContentView(R.layout.activity_main);     editText = (EditText) findViewById(R.id.editText1);     editText.setText("+374");     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().startsWith("+374")) {                 editText.setText("+374");                 Selection.setSelection(editText.getText(), editText                         .getText().length());              }          }      }); }  }
