Menu

在Activity里自定义menu，实现方法onCreateOptionsMenu(Menu menu)和onMenuItemSelected(int featureId, MenuItem item)。

Sample code：

import android.app.Activity;import android.os.Bundle;import android.view.Menu;import android.view.MenuInflater;import android.view.MenuItem;import android.widget.TextView;import android.widget.Toast;public class MenuView extends Activity {private Menu mMenu;@Overrideprotected void onCreate(Bundle savedInstanceState) {// TODO Auto-generated method stubsuper.onCreate(savedInstanceState);//LinearLayout layout = new LinearLayout(this);// layout.setOrientation(LinearLayout.VERTICAL);TextView tv = new TextView(this);tv.setText(getResources().getString(R.string.hello));//layout.addView(tv);setContentView(tv);}@Overridepublic boolean onCreateOptionsMenu(Menu menu) {// TODO Auto-generated method stubmMenu = menu;MenuInflater inflater = getMenuInflater();inflater.inflate(R.menu.menu1, mMenu);return true;}@Overridepublic boolean onMenuItemSelected(int featureId, MenuItem item) {// TODO Auto-generated method stubswitch(item.getItemId()){case R.id.jump:Toast.makeText(this, "This is jump",Toast.LENGTH_SHORT).show();return true;case R.id.dive:Toast.makeText(this, "This is dive", Toast.LENGTH_SHORT).show();return true;default:break;}return false;}}
