android – Event for Handling the Focus of the EditText

Posted by: admin March 11, 2020 Leave a comment

Questions:

Can anyone suggest me any event related to the focus of the EditText?
My application contains a EditText, which accepts a URL in it.

Now my problem is that, that after the user will enter the URL in the field and Move further, without any of the click event, i.e when the focus will move from the EditText, it should detect the entered Url and goes to the server.

If I get the reply using Json Parsing, then it’ll be more convenient.

How to&Answers:

Here is the focus listener example.

editText.setOnFocusChangeListener(new OnFocusChangeListener() {
    @Override
    public void onFocusChange(View view, boolean hasFocus) {
        if (hasFocus) {
            Toast.makeText(getApplicationContext(), "Got the focus", Toast.LENGTH_LONG).show();
        } else {
            Toast.makeText(getApplicationContext(), "Lost the focus", Toast.LENGTH_LONG).show();
        }
    }
});

Answer:

  1. Declare object of EditText on top of class:

     EditText myEditText;
    
  2. Find EditText in onCreate Function and setOnFocusChangeListener of EditText:

    myEditText = findViewById(R.id.yourEditTextNameInxml); 
    
    myEditText.setOnFocusChangeListener(new View.OnFocusChangeListener() {
                @Override
                public void onFocusChange(View view, boolean hasFocus) {
                    if (!hasFocus) {
                         Toast.makeText(this, "Focus Lose", Toast.LENGTH_SHORT).show();
                    }else{
                        Toast.makeText(this, "Get Focus", Toast.LENGTH_SHORT).show();
                    }
    
                }
            });
    

It works fine.

Answer:

when in kotlin it will look like this :

editText.setOnFocusChangeListener { view, hasFocus ->
        if (hasFocus) toast("focused") else toast("focuse lose")
    }

Answer:

For those of us who this above valid solution didnt work, there’s another workaround here

 searchView.setOnQueryTextFocusChangeListener(new View.OnFocusChangeListener() {
        @Override
        public void onFocusChange(View view, boolean isFocused) {
            if(!isFocused)
            {
                Toast.makeText(MainActivity.this,"not focused",Toast.LENGTH_SHORT).show();

            }
        }
    });
