Answer 1

java.lang.IllegalStateException: Could not find method clickTextView(View) in a parent or ancestor Context for android:onClick attribute defined on view class android.support.v7.widget.AppCompatEditText with id 'EnteredAmount'

In your layout, you appear to have android:onClick="clickTextView" . In your activity, you do not have a method named clickTextView() . You need to implement that method in your activity:

public void clickTextView(View v) {
 // whatever you want to do
}

Alternatively, you could remove the android:onClick="clickTextView" attribute from your <EditText> in your layout resource.

Answer 2

Perhaps you can use the multiple clickListener for views:

EditText EnteredAmount = (EditText) findViewById(R.id.EnteredAmount);
EnteredAmount.setOnClickListener(new View.OnClickListener() {

    @Override
    public void onClick(View v) {
        Toast.makeText(this, "I am clicked", Toast.LENGTH_SHORT).show;
    }
});
