Android：PopupWindow、自定义菜单
使用PopupWindow定制菜单界面： 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 125 126 127 128 public class MainActivity extends Activity { /** *menu的要求： *1.显示：点击menu键 *2.退出: *(1)再次点击menu *(2)点击menu选项 *(3)点击menu（通知除外）以外的地方 *(4)点击back键 *(5)进入暂停状态 * */ private PopupWindowmPopupMenu; @Override protected void onCreate(BundlesavedInstanceState) { super .onCreate(savedInstanceState); setContentView(R.layout.activity_main); LayoutInflaterinflater=getLayoutInflater(); Viewmenulayout=inflater.inflate(R.layout.optionmenu_layout, null ); mPopupMenu= new PopupWindow(menulayout,LayoutParams.MATCH_PARENT,LayoutParams.WRAP_CONTENT); //监听菜单按钮 menulayout.findViewById(R.id.textView1).setOnClickListener( new OnClickListener() { @Override public void onClick(Viewv) { mPopupMenu.dismiss(); } }); //点击菜单的layout就隐藏 menulayout.findViewById(R.id.mainmenu).setOnClickListener( new OnClickListener() { @Override public void onClick(Viewv) { mPopupMenu.dismiss(); } }); } //监听返回键 //@Override //publicvoidonBackPressed() //{ //if(mPopupMenu.isShowing()) //{ //mPopupMenu.dismiss(); //} //else //{ //super.onBackPressed(); //} //} //暂停状态 @Override protected void onPause() { if (mPopupMenu.isShowing()) { mPopupMenu.dismiss(); } super .onPause(); } //监听menu键和返回键 @Override public boolean onKeyDown( int keyCode,KeyEventevent) { if (keyCode==KeyEvent.KEYCODE_MENU) { if (mPopupMenu.isShowing()) { mPopupMenu.dismiss(); } else { mPopupMenu.showAtLocation(findViewById(R.id.main),Gravity.BOTTOM, 0 , 0 ); } return true ; } if (keyCode==KeyEvent.KEYCODE_BACK) { if (mPopupMenu.isShowing()) { mPopupMenu.dismiss(); } else { finish(); } return true ; } return super .onKeyDown(keyCode,event); } //4.2版本会默认自行启动此方法 /** @Override publicbooleanonCreateOptionsMenu(Menumenu) { if(mPopupMenu.isShowing()) { mPopupMenu.dismiss(); } else { mPopupMenu.showAtLocation(findViewById(R.id.main),Gravity.BOTTOM,0,0); } //设置成false，则每次按menu都会启动onCreateOptionsMenu方法，否则只在创建时启动一次 returnfalse; } */ } PopupWindow相关总结： 1.点击PopupWindow外区域关闭PopupWindow，监听PopupWindow 1 2 3 4 5 6 7 8 9 10 11 12 13 14 //设置电话菜单背景，点击菜单外区域隐藏菜单 mPhoneMenu.setBackgroundDrawable(getResources().getDrawable(R.color.emptylayout_bg)); //必须设置背景setOutsideTouchable才有效 mPhoneMenu.setFocusable( true ); //menu菜单获得焦点,menu里的控件才能有点击事件 mPhoneMenu.setOutsideTouchable( false ); //设置点击menu外的区域后隐藏menu mPhoneMenu.update(); //必须使用update方法 //监听菜单关闭时，打开底部菜单 mPhoneMenu.setOnDismissListener( new OnDismissListener() { @Override public void onDismiss() { showBottomMenu(); } }); 2.WindowManager$BadTokenException错误解决方法 http://glblong.blog.51cto.com/3058613/1306012 3.指定菜单在某个View的相对位置 1 2 3 4 5 6 7 8 9 10 popupWindow= new PopupWindow(layout, 120 , 120 ); //需要设置固定宽高,popupWindow.getHeight()才有效 popupWindow.setFocusable( true ); popupWindow.setOutsideTouchable( true ); popupWindow.setBackgroundDrawable( new BitmapDrawable()); int []location= new int [ 2 ]; //获取基准位置view的坐标位置 view.getLocationOnScreen(location); popupWindow.showAtLocation(view,Gravity.NO_GRAVITY,location[ 0 ],location[ 1 ]-popupWindow.getHeight()); 本文转自 glblong 51CTO博客，原文链接：http://blog.51cto.com/glblong/1225320，如需转载请自行联系原作者
