EditText setError() with icon but without Popup message

Question

I want to to have some validation for my EditText wherein I want to show "" icon (that comes when you put editText.setError("blah blah")) but don't want the text in the popup displaying that "blah blah".

Is there any way to do it? One way is to create a custom layout which will show the image icon in the EditText. But is there any better solution?

Problem solved after a lot of research and permutations- (Also thanks to @van)

Create a new class that will extend EditText something like this-

public class MyEditText extends EditText {  public MyEditText(Context context, AttributeSet attrs) {     super(context, attrs); }  @Override public void setError(CharSequence error, Drawable icon) {     setCompoundDrawables(null, null, icon, null); } } 

Use this class as a view in your xml like this-

<com.raj.poc.MyEditText     android:id="@+id/et_test"     android:layout_width="fill_parent"     android:layout_height="wrap_content"/> 

Now in the third step, just set a TextWatcher to your custom text view like this-

    et = (MyEditText) findViewById(R.id.et_test);      errorIcon = getResources().getDrawable(R.drawable.ic_error);     errorIcon.setBounds(new Rect(0, 0, errorIcon.getIntrinsicWidth(), errorIcon.getIntrinsicHeight()));        et.setError(null,errorIcon);      et.addTextChangedListener(new TextWatcher() {          @Override         public void onTextChanged(CharSequence s, int start, int before, int count) {         }          @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().length()>6){                 et.setError("", null);             }else{                 et.setError("", errorIcon);             }         }     }); 

where R.drawable.ic_error =

Keeping text null solves the problem But if we keep only null in setError(null), this won't show the validation error; it should be null along with second param.

You dont need to create a new EditText class or change xml. The solution is very simple:

Edittext editText= (EditText) rootView.findViewById(R.id.email);  String str= editText.getText().toString();  if(str.equalsIgnoreCase("") ){                  Drawable dr = getResources().getDrawable(R.drawable.error);                                   //add an error icon to yur drawable files                 dr.setBounds(0, 0, dr.getIntrinsicWidth(), dr.getIntrinsicHeight());                  editText.setCompoundDrawables(null,null,dr,null);              }
