Question

myButtonListener cannot be resolved to a type

public class MainActivity extends Activity { Button myButton; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.fragment_main); myButton=(Button)findViewById(R.id.myButton); myButton.setText("Button"); myButton.setOnClickListener(new myButtonListener()); class myButtonListener implements Button.OnClickListener{ @Override public void onClick(View v) { // TODO Auto-generated method stub Intent intent=new Intent(); intent.setClass(MainActivity.this, OtherActivity.class); MainActivity.this.startActivity(intent); } /*if (savedInstanceState == null) { getFragmentManager().beginTransaction() .add(R.id.container, new PlaceholderFragment()).commit(); }*/ }}

Answer 1

你的class myButtonListener implements Button.OnClickListener这个类应该子啊onCreate()函数写完后写，不能写在onCreate()函数内部。
