安卓菜单有三种菜单。
选项菜单: 点击系统菜单按钮会触发
上下文菜单:长按屏幕触发
子菜单:某一个菜单的下一级菜单
具体的描叙:http://blog.csdn.net/zqiang_55/article/details/7038085
写的简洁易懂。呵呵,其他的都太复杂了
我参考这个思路 写了一个演示代码。
package cn.wuwenfu.menudemo;import com.example.menudemo.R;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.MenuItem;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.Toast;public class MainActivity extends Activity {
private Button contextMenuButton;//上下文菜单
private Button subMenuButton;//子菜单
private Button optionMenuButton;//选项菜单@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.mainactivity);//获得3个按钮的控件
subMenuButton = (Button)this.findViewById(R.id.submenu_button);
contextMenuButton = (Button)this.findViewById(R.id.contextmenu_button);
optionMenuButton = (Button)this.findViewById(R.id.optionmenu_button);}
@Override
protected void onStart() {
// TODO Auto-generated method stub
super.onStart();contextMenuButton.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent in = new Intent();
in.setClass(MainActivity.this, ContextMenuActivity.class);
MainActivity.this.startActivity(in);}
});subMenuButton.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stubIntent in = new Intent();
in.setClass(MainActivity.this, SubMenuActivity.class);
MainActivity.this.startActivity(in);}
});}
//选项菜单
//如果触屏的平板则要注意sdk版本,过高会导致看不到菜单的图标//两种方法:第一种就是代码生成。第二种就是xml文件。
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// TODO Auto-generated method stub//add方法参数说明:参数一是分组的id,参数二:菜单的ID(最重要);参数三:菜单的排序,默认值0表示按照添加的顺序显示
/*menu.add(0, 0, 0, "查看");
menu.add(0, 1, 0, "修改");
menu.add(0, 2, 0, "删除");menu.add(1, 3, 0, "查看");
menu.add(1, 4, 0, "修改");
menu.add(1, 5, 0, "删除");//隐藏分组0
menu.setGroupVisible(0, false);
*///第二种方式
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.option_menu, menu);return super.onCreateOptionsMenu(menu);
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// TODO Auto-generated method stubswitch (item.getItemId()) {
/*
//是代码生成的,则是具体的数字
case 0:
Toast.makeText(MainActivity.this, "你点击率查看",
Toast.LENGTH_LONG).show();return true;
case 1:
Toast.makeText(MainActivity.this, "你点击率修改",
Toast.LENGTH_LONG).show();return true;
case 2:
Toast.makeText(MainActivity.this, "你点击率删除",
Toast.LENGTH_LONG).show();return true;
case 3:
Toast.makeText(MainActivity.this, "你点击率查看1",
Toast.LENGTH_LONG).show();return true;
case 4:
Toast.makeText(MainActivity.this, "你点击率修改1",
Toast.LENGTH_LONG).show();return true;
case 5:
Toast.makeText(MainActivity.this, "你点击率删除1",
Toast.LENGTH_LONG).show();return true;
*/
//上面的是基于add的菜单。下面的则是基于xml菜单
//由于这里采用的xml生成,id则必须是android:id对应的。
case R.id.menu1:
Toast.makeText(MainActivity.this, "菜单1", Toast.LENGTH_LONG).show();
return true;
case R.id.menu2:
Toast.makeText(MainActivity.this, "菜单2", Toast.LENGTH_LONG).show();
return true;
case R.id.menu3:
Toast.makeText(MainActivity.this, "菜单3", Toast.LENGTH_LONG).show();
return true;}
return false;
}
}
