Java file is used to write the program and all the actions that are performed on the widget while on the screen is done by the Java file.
MAIN ACTIVITY CODE : (file name - MainActivity.java)
package com.example.differentandroidcodes;
import androidx.appcompat.app.AppCompatActivity;
import android.os.Bundle;
import android.text.Editable;
import android.text.TextWatcher;
import android.widget.EditText;
import android.widget.Toast;
public class MainActivity extends AppCompatActivity {
EditText editText;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
editText = findViewById(R.id.editText);
editText.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) {
if (s.toString().length() > 0) {
Toast.makeText(MainActivity.this, s, Toast.LENGTH_SHORT).show();
}
else{
Toast.makeText(MainActivity.this, "There is no text written in the edit text", Toast.LENGTH_SHORT).show();
}
}
});
}
}
