为上下文菜单注册View

protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_main);
                                     
                                     
      button = (Button)findViewById(R.id.button);
      textView = (TextView)findViewById(R.id.textView);
      editText = (EditText)findViewById(R.id.editText);
                                     
      registerForContextMenu(textView);

填充上下文菜单

    public void onCreateContextMenu(ContextMenu menu, View v,
ContextMenuInfo menuInfo) {
if(v == textView)
{
menu.setHeaderTitle("Context Menu");
menu.add(1, 1, 1, "xia");
menu.add(1,2,3,"gegen");
}
if(v == button)
{
menu.setHeaderTitle("button Context Menu");
menu.add(1, 1, 1, "x");
menu.add(1,2,3,"g");
}
super.onCreateContextMenu(menu, v, menuInfo);
    }

响应

public boolean onContextItemSelected(MenuItem item) {
    // TODO Auto-generated method stub
    return super.onContextItemSelected(item);
}
