初学Android,引用了这篇文章的代码 http://www.cnblogs.com/jiezzy/archive/2012/08/15/2640584.html
使用PopupWindow制作自定义的菜单
先是Layout文件
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" > <LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center_horizontal"
android:orientation="horizontal" > <Button
android:id="@+id/menu_btnBackUp"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="5dp"
android:background="@drawable/backup"
android:layout_margin="0.5dp"
android:width="100dp" /> <Button
android:id="@+id/menu_btnRevert"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="5dp"
android:layout_margin="0.5dp"
android:background="@drawable/importing"
android:width="100dp" /> <Button
android:id="@+id/menu_btnCompany"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="5dp"
android:background="@drawable/company"
android:layout_margin="0.5dp"
android:width="100dp" />
</LinearLayout> <LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center_horizontal"
android:orientation="horizontal" > <Button
android:id="@+id/menu_btnCustom"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="0.5dp"
android:layout_marginTop="5dp"
android:background="@drawable/customer"
android:width="100dp" /> <Button
android:id="@+id/menu_btnTeSe"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="0.5dp"
android:layout_marginTop="5dp"
android:background="@drawable/tese"
android:width="100dp" /> <Button
android:id="@+id/menu_btnTool"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="0.5dp"
android:layout_marginTop="5dp"
android:background="@drawable/setting"
android:width="100dp" />
</LinearLayout> </LinearLayout>
然后是一个Activity
package com.tdcontactapp.lz; import com.tdcontactapp.CustomContactsActivity;
import com.tdcontactapp.EditAccountActivity;
import com.tdcontactapp.GroupContactsActivity;
import com.tdcontactapp.R;
import com.tdcontactapp.RecvertActivity;
import com.tdcontactapp.RemindActivity; import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.graphics.Color;
import android.graphics.drawable.ColorDrawable;
import android.os.Bundle;
import android.view.Gravity;
import android.view.KeyEvent;
import android.view.LayoutInflater;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.View.OnKeyListener;
import android.view.ViewGroup;
import android.view.ViewGroup.LayoutParams;
import android.widget.Button;
import android.widget.PopupWindow; public class LzMenuActivity extends Activity {
protected PopupWindow mPopupWindow = null;
protected Activity Context;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
showBottomMenu();
} public void showBottomMenu() {
Context mContext = this;
LayoutInflater mLayoutInfalter = (LayoutInflater) this
.getSystemService(LAYOUT_INFLATER_SERVICE);
View menuView = mLayoutInfalter.inflate(R.layout.lz_popup, null); mPopupWindow = new PopupWindow(menuView, LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT); mPopupWindow
.setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
mPopupWindow.setOutsideTouchable(true); // 设置是否允许在外点击使其消失，到底有用没？ mPopupWindow.setAnimationStyle(android.R.style.Animation_Dialog);
mPopupWindow.update();
mPopupWindow.setTouchable(true);
mPopupWindow.setFocusable(true); menuView.setFocusableInTouchMode(true);
menuView.setOnKeyListener(new OnKeyListener() {
@Override
public boolean onKey(View v, int keyCode, KeyEvent event) {
// TODO Auto-generated method stub
if ((keyCode == KeyEvent.KEYCODE_MENU)
&& (mPopupWindow.isShowing())) {
mPopupWindow.dismiss();// 这里写明模拟menu的PopupWindow退出就行
return true;
}
return false;
}
});
/* 设置点击menu以外其他地方以及返回键退出 */ Button btnBackup=(Button)menuView.findViewById(R.id.menu_btnBackUp);
Button btnRevert=(Button)menuView.findViewById(R.id.menu_btnRevert);
Button btnCompany=(Button)menuView.findViewById(R.id.menu_btnCompany);
Button btnCustom=(Button)menuView.findViewById(R.id.menu_btnCustom);
Button btnTese=(Button)menuView.findViewById(R.id.menu_btnTeSe);
Button btnTool=(Button)menuView.findViewById(R.id.menu_btnTool); btnBackup.setOnClickListener(new btnClick("menu_btnBackUp"));
btnRevert.setOnClickListener(new btnClick("menu_btnRevert"));
btnCompany.setOnClickListener(new btnClick("menu_btnCompany"));
btnCustom.setOnClickListener(new btnClick("menu_btnCustom"));
btnTese.setOnClickListener(new btnClick("menu_btnTeSe"));
btnTool.setOnClickListener(new btnClick("menu_btnTool"));
} private class btnClick implements OnClickListener{
private String name;
public btnClick(String name){
this.name=name;
}
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent intent=new Intent();
if(name.equals("menu_btnBackUp")){
intent.setClass(LzMenuActivity.this,CustomContactsActivity.class);
}
if(name.equals("menu_btnRevert")){
intent.setClass(LzMenuActivity.this,RecvertActivity.class);
}
if(name.equals("menu_btnCompany")){
intent.setClass(LzMenuActivity.this,GroupContactsActivity.class);
}
if(name.equals("menu_btnCustom")){
intent.setClass(LzMenuActivity.this,CustomContactsActivity.class);
}
if(name.equals("menu_btnTeSe")){
intent.setClass(LzMenuActivity.this,RemindActivity.class);
}
if(name.equals("menu_btnTool")){
intent.setClass(LzMenuActivity.this,EditAccountActivity.class);
}
startActivity(intent);
} } @Override
public boolean onCreateOptionsMenu(Menu menu) {
//Toast.makeText(LzMenuActivity.this, "菜单事件", Toast.LENGTH_LONG).show();
menu.add("menu");// 必须创建一项
return super.onCreateOptionsMenu(menu);
} @Override
public boolean onMenuOpened(int featureId, Menu menu) {
if (mPopupWindow != null) {
if (!mPopupWindow.isShowing()) {
/* 最重要的一步：弹出显示 在指定的位置(parent) 最后两个参数 是相对于 x / y 轴的坐标 */
View v= ((ViewGroup)findViewById(android.R.id.content)).getChildAt(0);
if(v==null)
return false;
mPopupWindow.showAtLocation(v,
Gravity.BOTTOM, 0, 0);
}
}
return false;// 返回为true 则显示系统menu
} }
只要另一个需要显示自定义菜单 的Activity 继承上面的类，就可以显示菜单
