android系统menu菜单选项设置

首先在menu文件下的mai.xml写好按钮设置，

<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    tools:context="com.xh.tx.menue.MainActivity" >

    <item
        android:id="@+id/action_settings1"
        android:orderInCategory="100"
        android:showAsAction="never"
        android:title="@string/action_settings11"/>
    <item
        android:id="@+id/action_settings2"
        android:orderInCategory="101"
        android:showAsAction="never"
        android:title="@string/action_settings22"/>
    <item
        android:id="@+id/action_settings3"
        android:orderInCategory="102"
        android:showAsAction="never"
        android:title="@string/action_settings33"/>
    <item
        android:id="@+id/action_settings4"
        android:orderInCategory="104"
        android:showAsAction="never"
        android:title="@string/action_settings55"/>

</menu>

抽取出来的中文字符在values文件下的strings.xml里：

<?xml version="1.0" encoding="utf-8"?>
<resources>

    <string name="app_name">Menue</string>
    <string name="action_settings11">设置</string>
    <string name="action_settings22">关于</string>
    <string name="action_settings33">帮助</string>
    <string name="action_settings55">退出</string>
    <string name="weixin">微信</string>

</resources>

然后在java代码里写好代码：

public class MainActivity extends Activity {

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
	}
	@Override
	public boolean onCreateOptionsMenu(Menu menu) {
		// Inflate the menu; this adds items to the action bar if it is present.
		getMenuInflater().inflate(R.menu.main, menu);
		return true;
	}

	@Override
	public boolean onOptionsItemSelected(MenuItem item) {
		// Handle action bar item clicks here. The action bar will
		// automatically handle clicks on the Home/Up button, so long
		// as you specify a parent activity in AndroidManifest.xml.
		int id = item.getItemId();
		switch (id) {
		case R.id.action_settings1:
			Toast.makeText(this, item.getTitle(), Toast.LENGTH_LONG).show();
			break;
		case R.id.action_settings2:
			Toast.makeText(this, item.getTitle(), Toast.LENGTH_LONG).show();
			break;
		case R.id.action_settings3:
			Toast.makeText(this, item.getTitle(), Toast.LENGTH_LONG).show();
			break;
		case R.id.action_settings4:
			Toast.makeText(this, item.getTitle(), Toast.LENGTH_LONG).show();
			break;
		
		}
		return super.onOptionsItemSelected(item);
	}
}

这样点击menu按钮就会出现下图：

这就是简单的menu设置。
