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、
<menu xmlns:android="http://schemas.android.com/apk/res/android"> <item android:id="@+id/about" android:title="关于" android:checkable="true" /> <item android:id="@+id/choose" android:title="选择" /> <item android:id="@+id/quit" android:title="QUIT" /> </menu>
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)
{/*
String[] aryShop = getResources().getStringArray(R.array.items_irdc_dialog);
new AlertDialog.Builder(this)
.setMessage(R.string.app_about_msg)
.setPositiveButton(R.string.str_ok, new DialogInterface.OnClickListener()
{
public void onClick(DialogInterface dialoginterface, int i)
{
}
})
.show();*/
}
})
.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)
{/*
String[] aryShop = getResources().getStringArray(R.array.items_irdc_dialog);
new AlertDialog.Builder(this)
.setMessage(R.string.app_about_msg)
.setPositiveButton(R.string.str_ok, new DialogInterface.OnClickListener()
{
public void onClick(DialogInterface dialoginterface, int i)
{
}
})
.show();*/
}
})
.show();
}
