Android 底部弹出Dialog(横向满屏)

项目中经常需要底部弹出框,这里我整理一下其中我用的比较顺手的一个方式(底部弹出一个横向满屏的dialog)。

效果图如下所示(只显示关键部分):

步骤如下所示:

1.定义一个dialog的布局(lay_share.xml)

 1 <?xml version="1.0" encoding="utf-8"?>
 2 
 3 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
 4     android:layout_width="match_parent"
 5     android:layout_height="match_parent"
 6     android:background="@color/white"
 7     android:orientation="vertical">
 8 
 9     <LinearLayout
10         android:layout_width="match_parent"
11         android:layout_height="wrap_content"
12         android:gravity="center_vertical"
13         android:orientation="horizontal"
14         android:paddingBottom="@dimen/padding_15"
15         android:paddingTop="@dimen/padding_15">
16 
17         <View
18             android:layout_width="0dp"
19             android:layout_height="0dp"
20             android:layout_weight="1" />
21 
22         <TextView
23             android:layout_width="wrap_content"
24             android:layout_height="wrap_content"
25             android:drawablePadding="@dimen/padding_5"
26             android:drawableTop="@mipmap/ic_weixin_share"
27             android:gravity="center"
28             android:text="微信"
29             android:textColor="@color/color_999999"
30             android:textSize="@dimen/text_14" />
31 
32         <View
33             android:layout_width="0dp"
34             android:layout_height="0dp"
35             android:layout_weight="1" />
36 
37         <TextView
38             android:layout_width="wrap_content"
39             android:layout_height="wrap_content"
40             android:drawablePadding="@dimen/padding_5"
41             android:drawableTop="@mipmap/ic_circle_share"
42             android:gravity="center"
43             android:text="朋友圈"
44             android:textColor="@color/color_999999"
45             android:textSize="@dimen/text_14" />
46 
47         <View
48             android:layout_width="0dp"
49             android:layout_height="0dp"
50             android:layout_weight="1" />
51 
52         <TextView
53             android:layout_width="wrap_content"
54             android:layout_height="wrap_content"
55             android:drawablePadding="@dimen/padding_5"
56             android:drawableTop="@mipmap/ic_weibo_share"
57             android:gravity="center"
58             android:text="微博"
59             android:textColor="@color/color_999999"
60             android:textSize="@dimen/text_14" />
61 
62         <View
63             android:layout_width="0dp"
64             android:layout_height="0dp"
65             android:layout_weight="1" />
66     </LinearLayout>
67 
68     <View
69         android:layout_width="match_parent"
70         android:layout_height="0.5dp"
71         android:layout_marginLeft="@dimen/padding_10"
72         android:layout_marginRight="@dimen/padding_10"
73         android:background="@color/color_c9c9c9" />
74 
75     <TextView
76         android:id="@+id/tv_cancel"
77         android:layout_width="match_parent"
78         android:layout_height="wrap_content"
79         android:gravity="center"
80         android:padding="@dimen/padding_15"
81         android:text="取消"
82         android:textColor="@color/color_666666"
83         android:textSize="@dimen/text_18" />
84 </LinearLayout>
View Code

2.定义弹出框弹出动画(dialog_enter.xml)

1 <?xml version="1.0" encoding="utf-8"?>
2 <set xmlns:android="http://schemas.android.com/apk/res/android">
3     <translate
4         android:duration="300"
5         android:fromYDelta="100%p"
6         android:toYDelta="0" />
7 </set>
dialog_enter.xml

3.定义弹出框隐藏动画(dialog_exit.xml)

1 <?xml version="1.0" encoding="utf-8"?>
2 <set xmlns:android="http://schemas.android.com/apk/res/android">
3     <translate
4         android:duration="300"
5         android:fromYDelta="0"
6         android:toYDelta="100%p" />
7 </set>
dialog_exit.xml

4.定义动画style

1 <!--弹出框动画-->
2     <style name="share_animation" parent="android:Animation">
3         <item name="android:windowEnterAnimation">@anim/dialog_enter</item>
4         <item name="android:windowExitAnimation">@anim/dialog_exit</item>
5     </style>
View Code

5.定义对话框样式

1 <!-- 对话框样式 -->
2     <style name="dialog_bottom_full" parent="android:style/Theme.Dialog">
3         <item name="android:windowBackground">@android:color/transparent</item>
4         <item name="android:windowNoTitle">true</item>
5         <item name="android:windowIsFloating">true</item>
6         <item name="android:windowContentOverlay">@null</item>
7         <item name="android:scrollHorizontally">true</item>
8     </style>
View Code

6.最后,在需要从底部弹出dialog的地方,直接调用showDialog()方法

 1 /**
 2      * 显示分享弹出框
 3      */
 4     private void showDialog() {
 5         if (mShareDialog == null) {
 6             initShareDialog();
 7         }
 8         mShareDialog.show();
 9     }
10 
11     /**
12      * 初始化分享弹出框
13      */
14     private void initShareDialog() {
15         mShareDialog = new Dialog(this, R.style.dialog_bottom_full);
16         mShareDialog.setCanceledOnTouchOutside(true);
17         mShareDialog.setCancelable(true);
18         Window window = mShareDialog.getWindow();
19         window.setGravity(Gravity.BOTTOM);
20         window.setWindowAnimations(R.style.share_animation);
21         View view = View.inflate(this, R.layout.lay_share, null);
22         view.findViewById(R.id.tv_cancel).setOnClickListener(new View.OnClickListener() {
23             @Override
24             public void onClick(View view) {
25                 if (mShareDialog != null && mShareDialog.isShowing()) {
26                     mShareDialog.dismiss();
27                 }
28             }
29         });
30         window.setContentView(view);
31         window.setLayout(WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.WRAP_CONTENT);//设置横向全屏
32     }
View Code

大功告成!

收工!
