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、
<menuxmlns:android="http://schemas.android.com/apk/res/android"> <itemandroid:id="@+id/about" android:title="关于" android:checkable="true"/> <itemandroid:id="@+id/choose" android:title="选择"/> <itemandroid:id="@+id/quit" android:title="QUIT"/> </menu>
2、activity类中加入代码
publicbooleanonCreateOptionsMenu(Menumenu){
MenuInflaterinflater=getMenuInflater();
inflater.inflate(R.menu.options_menu,menu);
returnsuper.onCreateOptionsMenu(menu);
}
publicbooleanonOptionsItemSelected(MenuItemaitem)
{
super.onOptionsItemSelected(aitem);
switch(aitem.getItemId())
{
caseR.id.about:
setTitle("你按下了'关于'菜单项");
progressBarHorizontal.setProgress(200);
openOptionsDialog();
break;
caseR.id.choose:
setTitle("你按下了'选择'菜单项");
openOptionsChooseDialog();
break;
caseR.id.quit:
setTitle("你按下了'离开'菜单项");
finish();
break;
}
returntrue;
}
privatevoidopenOptionsDialog()
{
newAlertDialog.Builder(this)
.setTitle(R.string.app_about)
.setMessage(R.string.app_about_msg)
.setPositiveButton(R.string.str_ok,newDialogInterface.OnClickListener()
{
publicvoidonClick(DialogInterfacedialoginterface,inti)
{
}
})
.show();
}
privatevoidopenOptionsChooseDialog()
{
newAlertDialog.Builder(this)
.setTitle(R.string.str_alert)
.setItems(R.array.items_irdc_dialog,newDialogInterface.OnClickListener()
{
publicvoidonClick(DialogInterfacedialoginterface,inti)
{/*
String[]aryShop=getResources().getStringArray(R.array.items_irdc_dialog);
newAlertDialog.Builder(this)
.setMessage(R.string.app_about_msg)
.setPositiveButton(R.string.str_ok,newDialogInterface.OnClickListener()
{
publicvoidonClick(DialogInterfacedialoginterface,inti)
{
}
})
.show();*/
}
})
.show();
}
OK。。。
二、直接上代码：
publicstaticfinalintABOUT_ID=Menu.FIRST;
publicstaticfinalintCHOOSE_ID=Menu.FIRST+1;
publicstaticfinalintEXIT_ID=Menu.FIRST+2;
publicbooleanonCreateOptionsMenu(Menumenu)
{
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);
returnsuper.onCreateOptionsMenu(menu);
}
publicbooleanonOptionsItemSelected(MenuItemaitem)
{
super.onOptionsItemSelected(aitem);
switch(aitem.getItemId())
{
caseABOUT_ID:
setTitle("你按下了'关于'菜单项");
progressBarHorizontal.setProgress(200);
openOptionsDialog();
break;
caseCHOOSE_ID:
setTitle("你按下了'选择'菜单项");
openOptionsChooseDialog();
break;
caseEXIT_ID:
setTitle("你按下了'离开'菜单项");
finish();
break;
}
returntrue;
}
privatevoidopenOptionsDialog()
{
newAlertDialog.Builder(this)
.setTitle(R.string.app_about)
.setMessage(R.string.app_about_msg)
.setPositiveButton(R.string.str_ok,newDialogInterface.OnClickListener()
{
publicvoidonClick(DialogInterfacedialoginterface,inti)
{
}
})
.show();
}
privatevoidopenOptionsChooseDialog()
{
newAlertDialog.Builder(this)
.setTitle(R.string.str_alert)
.setItems(R.array.items_irdc_dialog,newDialogInterface.OnClickListener()
{
publicvoidonClick(DialogInterfacedialoginterface,inti)
{/*
String[]aryShop=getResources().getStringArray(R.array.items_irdc_dialog);
newAlertDialog.Builder(this)
.setMessage(R.string.app_about_msg)
.setPositiveButton(R.string.str_ok,newDialogInterface.OnClickListener()
{
publicvoidonClick(DialogInterfacedialoginterface,inti)
{
}
})
.show();*/
}
})
.show();
}
