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;
- }
- }
