Android PopupWindow菜单
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
1 <?xml version="1.0" encoding="utf-8"?> 2 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 3 android:layout_width="match_parent" 4 android:layout_height="match_parent" 5 android:orientation="vertical" > 6 7 <LinearLayout 8 android:layout_width="match_parent" 9 android:layout_height="wrap_content" 10 android:gravity="center_horizontal" 11 android:orientation="horizontal" > 12 13 <Button 14 android:id="@+id/menu_btnBackUp" 15 android:layout_width="wrap_content" 16 android:layout_height="wrap_content" 17 android:layout_marginTop="5dp" 18 android:background="@drawable/backup" 19 android:layout_margin="0.5dp" 20 android:width="100dp" /> 21 22 <Button 23 android:id="@+id/menu_btnRevert" 24 android:layout_width="wrap_content" 25 android:layout_height="wrap_content" 26 android:layout_marginTop="5dp" 27 android:layout_margin="0.5dp" 28 android:background="@drawable/importing" 29 android:width="100dp" /> 30 31 <Button 32 android:id="@+id/menu_btnCompany" 33 android:layout_width="wrap_content" 34 android:layout_height="wrap_content" 35 android:layout_marginTop="5dp" 36 android:background="@drawable/company" 37 android:layout_margin="0.5dp" 38 android:width="100dp" /> 39 </LinearLayout> 40 41 <LinearLayout 42 android:layout_width="match_parent" 43 android:layout_height="match_parent" 44 android:gravity="center_horizontal" 45 android:orientation="horizontal" > 46 47 <Button 48 android:id="@+id/menu_btnCustom" 49 android:layout_width="wrap_content" 50 android:layout_height="wrap_content" 51 android:layout_margin="0.5dp" 52 android:layout_marginTop="5dp" 53 android:background="@drawable/customer" 54 android:width="100dp" /> 55 56 <Button 57 android:id="@+id/menu_btnTeSe" 58 android:layout_width="wrap_content" 59 android:layout_height="wrap_content" 60 android:layout_margin="0.5dp" 61 android:layout_marginTop="5dp" 62 android:background="@drawable/tese" 63 android:width="100dp" /> 64 65 <Button 66 android:id="@+id/menu_btnTool" 67 android:layout_width="wrap_content" 68 android:layout_height="wrap_content" 69 android:layout_margin="0.5dp" 70 android:layout_marginTop="5dp" 71 android:background="@drawable/setting" 72 android:width="100dp" /> 73 </LinearLayout> 74 75 </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
