Android 系统菜单与自定义菜单
Android 系统菜单与自定义菜单实现方法如下：系统菜单显示DefaultMenu.java
package com.wxz.menu;
import com.wxz.menu.R;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
import android.widget.Toast;
public class DefaultMenu extends Activity {
private Button btnCustomizeMenu;
private TextView tvTip;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
this.setTitle("Android 系统菜单");
btnCustomizeMenu = (Button)findViewById(R.id.btnCustomizeMenu);
btnCustomizeMenu.setOnClickListener(new ClickEvent());
tvTip = (TextView)findViewById(R.id.tvTip);
tvTip.setText("请按Menu键(F2)显示系统菜单");
}
class ClickEvent implements View.OnClickListener{
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
if(v==btnCustomizeMenu){
Intent it = new Intent();
it.setClass(DefaultMenu.this, CustomizeMenu.class);
startActivity(it);
}
}
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
/*
*
* add()方法的四个参数，依次是：
*
* 1、组别，如果不分组的话就写Menu.NONE,
*
* 2、Id，这个很重要，Android根据这个Id来确定不同的菜单
*
* 3、顺序，那个菜单现在在前面由这个参数的大小决定
*
* 4、文本，菜单的显示文本
*/
menu.add(Menu.NONE, Menu.FIRST + 1, 2, "删除").setIcon(
android.R.drawable.ic_menu_delete);
// setIcon()方法为菜单设置图标，这里使用的是系统自带的图标，以
// android.R开头的资源是系统提供的，我们自己提供的资源是以R开头的
menu.add(Menu.NONE, Menu.FIRST + 2, 3, "保存").setIcon(
android.R.drawable.ic_menu_edit);
menu.add(Menu.NONE, Menu.FIRST + 3, 4, "帮助").setIcon(
android.R.drawable.ic_menu_help);
menu.add(Menu.NONE, Menu.FIRST + 4, 1, "添加").setIcon(
android.R.drawable.ic_menu_add);
//返回true则显示，返回false则不显示
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case Menu.FIRST + 1:
Toast.makeText(this, "删除菜单被点击了", Toast.LENGTH_LONG).show();
break;
case Menu.FIRST + 2:
Toast.makeText(this, "保存菜单被点击了", Toast.LENGTH_LONG).show();
break;
case Menu.FIRST + 3:
Toast.makeText(this, "帮助菜单被点击了", Toast.LENGTH_LONG).show();
break;
case Menu.FIRST + 4:
Toast.makeText(this, "添加菜单被点击了", Toast.LENGTH_LONG).show();
break;
}
// 返回false则正常显示，返回true则被消费掉
return false;
}
@Override
public void onOptionsMenuClosed(Menu menu) {
Toast.makeText(this, "选项菜单关闭了", Toast.LENGTH_LONG).show();
}
@Override
public boolean onPrepareOptionsMenu(Menu menu) {
Toast.makeText(this,
"选项菜单显示之前onPrepareOptionsMenu方法会被调用，你可以用此方法来根据打当时的情况调整菜单",
Toast.LENGTH_LONG).show();
// 如果返回false，此方法就把用户点击menu的动作给消费了，onCreateOptionsMenu方法将不会被调用
return true;
}
