Android On Focus Change

Question

I want to update an EditText when a user changes focus from the edittext to another item I want to check the contents of the edittext eg is the number larger than 10 if so change it to 10.

How should I do this.

Answer 1

set setOnFocusChangeListener to your edittext...

editText.setOnFocusChangeListener(new OnFocusChangeListener() {

            @Override
            public void onFocusChange(View v, boolean hasFocus) {

                if(!hasFocus){
              //this if condition is true when edittext lost focus...
              //check here for number is larger than 10 or not
                    editText.setText("10");
                }
            }
        });

Answer 2

 EditText ET =(EditText)findViewById(R.id.yourtextField);
ET.setOnFocusChangeListener(new OnFocusChangeListener() {
            public void onFocusChange(View arg0, boolean arg1) {

String myText = ET.getText();
//Do whatever

}
