註冊操作功能表：（長按彈出一個菜單）
第一種建立方法（與長按事件結合）：
public class MainActivity extends Activity {
private TextView username,password;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
username = (TextView) findViewById(R.id.username);
password = (TextView) findViewById(R.id.password);
username.setOnCreateContextMenuListener(new OnCreateContextMenuListener() {
@Override
public void onCreateContextMenu(ContextMenu menu, View v,
ContextMenuInfo menuInfo) {
// TODO Auto-generated method stub
menu.add("file");
menu.add("edit");
menu.add("source");
}
});
}
@Override
public boolean onContextItemSelected(MenuItem item) {
// TODO Auto-generated method stub
//當菜單上下文元素被選中時執行
Toast.makeText(this, item.getTitle()+"onContextItemSelected", 1).show();
return super.onContextItemSelected(item);
}
@Override
public boolean onMenuItemSelected(int featureId, MenuItem item) {
// TODO Auto-generated method stub
//菜單元素被選中時執行
Toast.makeText(this, item.getTitle()+"onMenuItemSelected", 1).show();
return super.onMenuItemSelected(featureId, item);
}
}

setContentView(R.layout.activity_main);
username = (TextView) findViewById(R.id.username);
password = (TextView) findViewById(R.id.password);
this.registerForContextMenu(username);//註冊菜單
}
@Override
public void onCreateContextMenu(ContextMenu menu, View v,
ContextMenuInfo menuInfo) {
// TODO Auto-generated method stub
menu.add("file");
menu.add("edit");
