package com.xxx.xxx.xxx; import android.content.Intent; import android.support.v7.app.AppCompatActivity; import android.os.Bundle; import android.view.View; import android.widget.Button; public class Main extends AppCompatActivity { static { System.loadLibrary("native-lib"); } @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); final String mAnswer; final Button mButtonAns;   mAnswer = "xxx"; mButtonAns = (Button)findViewById(R.id.test_ans); mButtonAns.setOnClickListener(new View.OnClickListener(){ @Override public void onClick(View view) { if (mButtonAns.getText() == mAnswer) { Intent i = new Intent(Main.this, True.class); startActivity(i); //^go to true activity } else { //go to false activity } } }); } } 

i tried delete @Override public void onClick(View view), the getText() become red, is that onClick is the problem? please help ;(
