android创建optionsmenu的方法

本文实例讲述了android创建optionsmenu的方法。分享给大家供大家参考。具体实现方法如下：

一、用xml配置

在res文件夹下新建menu文件夹，menu下新建options_menu.xml文件，加入代码

1、

2、activity类中加入代码

public boolean onCreateOptionsMenu(Menu menu) {
 MenuInflater inflater = getMenuInflater();
 inflater.inflate(R.menu.options_menu, menu);
 return super.onCreateOptionsMenu(menu);
 }
 public boolean onOptionsItemSelected(MenuItem aitem)
 {
 super.onOptionsItemSelected(aitem);
 switch(aitem.getItemId())
 {
 case R.id.about:
 setTitle("你按下了'关于'菜单项");
 progressBarHorizontal.setProgress(200);
 openOptionsDialog();
 break;
 case R.id.choose:
 setTitle("你按下了'选择'菜单项");
 openOptionsChooseDialog();
 break;
 case R.id.quit:
 setTitle("你按下了'离开'菜单项");
 finish();
 break;
 }
 return true;
 }
 private void openOptionsDialog()
 {
 new alertDialog.Builder(this)
 .setTitle(R.string.app_about)
 .setMessage(R.string.app_about_msg)
 .setPositiveButton(R.string.str_ok, new DialogInterface.onClickListener()
 {
 public void onClick(DialogInterface dialoginterface, int i)
 {
 }
 })
 .show();
 }
 private void openOptionsChooseDialog()
 {
 new alertDialog.Builder(this)
 .setTitle(R.string.str_alert)
 .setItems(R.array.items_irdc_dialog, new DialogInterface.onClickListener()
 {
 public void onClick(DialogInterface dialoginterface, int i)
 {
 }
 })
 .show();
}

OK。。。

二、直接上代码：

public static final int about_ID = Menu.FIRST;
public static final int CHOOSE_ID = Menu.FIRST + 1;
public static final int EXIT_ID = Menu.FIRST + 2;
public boolean onCreateOptionsMenu(Menu menu)
{
 menu.add(0, about_ID, 0, R.string.app_about);
 menu.add(0, CHOOSE_ID, 0, R.string.str_choose);
 menu.add(0, EXIT_ID, 0, R.string.str_exit);
 return super.onCreateOptionsMenu(menu);
 }
 public boolean onOptionsItemSelected(MenuItem aitem)
 {
 super.onOptionsItemSelected(aitem);
 switch(aitem.getItemId())
 {
 case about_ID:
 setTitle("你按下了'关于'菜单项");
 progressBarHorizontal.setProgress(200);
 openOptionsDialog();
 break;
 case CHOOSE_ID:
 setTitle("你按下了'选择'菜单项");
 openOptionsChooseDialog();
 break;
 case EXIT_ID:
 setTitle("你按下了'离开'菜单项");
 finish();
 break;
 }
 return true;
 }
 private void openOptionsDialog()
 {
 new alertDialog.Builder(this)
 .setTitle(R.string.app_about)
 .setMessage(R.string.app_about_msg)
 .setPositiveButton(R.string.str_ok, new DialogInterface.onClickListener()
 {
 public void onClick(DialogInterface dialoginterface, int i)
 {
  
 }
 })
 .show();
 }
 private void openOptionsChooseDialog()
 {
 new alertDialog.Builder(this)
 .setTitle(R.string.str_alert)
 .setItems(R.array.items_irdc_dialog, new DialogInterface.onClickListener()
 {
 public void onClick(DialogInterface dialoginterface, int i)
 {
 }
 })
 .show();
}

希望本文所述对大家的Android程序设计有所帮助。
