android Menu 菜单使用总结
首先建议阅读官方提供的API阅读：
http://developer.android.com/guide/topics/ui/menus.html#context-menu
阅读之后简单写其中的某些功能，先贴图：
第一步：
相关代码：
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:id="@+id/item1"
android:icon="@drawable/about_icon"
android:showAsAction="always"
android:title="item1">
<menu>
<item
android:id="@+id/create_new"
android:title="new "/>
<item
android:id="@+id/open"
android:title="open"/>
</menu>
<item/>
<item
android:id="@+id/item2"
android:icon="@drawable/abs__ic_search"
android:showAsAction="ifRoom"
android:title="item2">
<!-- menu group -->
<group
android:id="@+id/group"
>
<item
android:id="@+id/groupitem1"
android:showAsAction="ifRoom"
android:title="groupitem1"/>
<item
android:id="@+id/groupitem2"
android:showAsAction="ifRoom"
android:title="groupitem2"/>
</group>
<item/>
<item
android:id="@+id/item3"
android:icon="@drawable/ad_def_logo"
android:showAsAction="always"
android:title="item3"/>
<item
android:id="@+id/item4"
android:icon="@drawable/abs__ic_voice_search"
android:showAsAction="always"
android:title="item4"/>
<item
android:id="@+id/item5"
android:icon="@drawable/abs__ic_voice_search"
android:showAsAction="never"
android:title="item5"/>
</item>
</item>
</menu>第二步：
代码中的实现：
package com.jiaruihuademo.testmenu;
import java.util.ArrayList;
import java.util.List;
import android.os.Bundle;
import android.annotation.SuppressLint;
import android.app.Activity;
import android.view.ContextMenu;
import android.view.ContextMenu.ContextMenuInfo;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.MenuItem;
import android.view.View;
import android.view.View.OnCreateContextMenuListener;
import android.widget.AdapterView;
import android.widget.AdapterView.AdapterContextMenuInfo;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.PopupMenu;
import android.widget.PopupMenu.OnMenuItemClickListener;
import android.widget.Toast;

@SuppressLint("NewApi")
public class MainActivity extends Activity implements OnMenuItemClickListener,
OnCreateContextMenuListener, OnItemClickListener {
private ListView listview;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
listview = (ListView) findViewById(R.id.listView1);
List<String> list = new ArrayList<String>();
for (int i = 0; i < 20; i++) {
list.add(i + "");
}
listview.setAdapter(new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1, list));
listview.setOnItemClickListener(this);
}
/**
* 创建popviewMenu
*
* @param v
*/
@SuppressLint("NewApi")
public void showpop(View v) {
PopupMenu popup = new PopupMenu(this, v);
MenuInflater inflater = popup.getMenuInflater();
inflater.inflate(R.menu.main, popup.getMenu());
popup.setOnMenuItemClickListener(this);
popup.show();
}
@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;
}
/*

*
* @see android.app.Activity#onOptionsItemSelected(android.view.MenuItem)
*/
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.item1:
Toast.makeText(this, "you have clicked 1 ", 0).show();
break;
case R.id.item2:
Toast.makeText(this, "you have clicked 2 ", 0).show();
break;
case R.id.item3:
Toast.makeText(this, "you have clicked 3 ", 0).show();
break;
case R.id.item4:
Toast.makeText(this, "you have clicked 4 ", 0).show();
break;
default:
break;
}
return super.onOptionsItemSelected(item);
}
/**
* 响应popmenu的点击事件
*/
@Override
public boolean onMenuItemClick(MenuItem item) {
switch (item.getItemId()) {
case R.id.item1:
Toast.makeText(this, "you have clicked 1 ", 0).show();
break;
case R.id.item2:
Toast.makeText(this, "you have clicked 2 ", 0).show();
break;
case R.id.item3:
Toast.makeText(this, "you have clicked 3 ", 0).show();
break;
case R.id.item4:
Toast.makeText(this, "you have clicked 4 ", 0).show();
break;
default:
break;
}
return false;
}
/**
* listview响应事件
*/
@Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
// TODO Auto-generated method stub
registerForContextMenu(view);
}
@Override
public void onCreateContextMenu(ContextMenu menu, View v,
ContextMenuInfo menuInfo) {
super.onCreateContextMenu(menu, v, menuInfo);
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.main, menu);
}
@Override
public boolean onContextItemSelected(MenuItem item) {
AdapterContextMenuInfo info = (AdapterContextMenuInfo) item
.getMenuInfo();
switch (item.getItemId()) {
case R.id.item1:
Toast.makeText(this, "you have clicked 1 ", 0).show();
return true;
case R.id.item2:
Toast.makeText(this, "you have clicked 2 ", 0).show();
return true;
case R.id.item3:
Toast.makeText(this, "you have clicked 3 ", 0).show();
return true;
case R.id.item4:
Toast.makeText(this, "you have clicked 4 ", 0).show();
return true;
default:
return super.onContextItemSelected(item);
}
}
}
第三步;附上布局文件：
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context=".MainActivity" >
<TextView
android:id="@+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/hello_world" />
<Button
android:id="@+id/showpop"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@+id/textView1"
android:layout_marginTop="16dp"
android:text="show popmenu"
android:onClick="showpop" />
<ListView
android:id="@+id/listView1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignLeft="@+id/showpop"
android:layout_below="@+id/showpop"
android:layout_marginTop="40dp" >
</ListView>
</RelativeLayout>
备注;
我使用的
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="18" />
