1, the effect of FIG.

 

 

 

achieve

1, the bottom of the pop layout (dialog.xml)

<?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:background="#fff"
    android:orientation="vertical">

    <TextView
        android:id="@+id/tv_take_photo"
        android:layout_width="match_parent"
        android:layout_height="50dp"
        android:gravity="center"
        android:text="拍摄"
        android:textColor="@android:color/background_dark"
        android:textSize="16sp" />

    <View
        android:layout_width="match_parent"
        android:layout_height="1dp"
        android:background="@android:color/darker_gray" />

    <TextView
        android:id="@+id/tv_take_pic"
        android:layout_width="match_parent"
        android:layout_height="50dp"
        android:gravity="center"
        android:text="相册选择"
        android:textColor="@android:color/background_dark"
        android:textSize="16sp" />

    <View
        android:layout_width="match_parent"
        android:layout_height="5dp"
        android:background="@android:color/darker_gray" />

    <TextView
        android:id="@+id/tv_cancel"
        android:layout_width="match_parent"
        android:layout_height="50dp"
        Android: Gravity = "Center" 
        Android: text = "Cancel" 
        Android: textColor = "@ Android: Color / background_dark" 
        Android: textSize = "16SP" /> 

</ LinearLayout> 

2, set the pop-up, exit the movie 
 
I, in res New resource file directory file anim 
Second, the new layout in the anim file 

  1, comes into play animation 
　　　　dialog_in_anim.xml

<? XML Version = "1.0" encoding = "UTF-. 8"?> 
<SET xmlns: Android = "http://schemas.android.com/apk/res/android"> 
    <Translate 
        Android: DURATION = "300" // animation execution time 
        Android: fromXDelta = "0" 
        Android: fromYDelta = "1000" from the bottom of the pop-up // 
        Android: toXDelta = "0" 
        Android: toYDelta = "0" /> 

</ SET>

  1, exit animation 
　　　dialog_out_anim.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <translate
        android:duration="300"
        android:fromXDelta="0"
        android:fromYDelta="0"
        android:toXDelta="0"
        android:toYDelta="1000"//回到屏幕外
 />

</set>
3、style 样式

<style name="DialogTheme" parent="@android:style/Theme.Dialog">
    <!-- 边框 -->
    <item name="android:windowFrame">@null</item>
    <!-- 是否浮现在activity之上 -->
    <item name="android:windowIsFloating">true</item>
    <!-- 半透明 -->
    <item name="android:windowIsTranslucent">true</item>
    <!-- 无标题 -->
    <item name="android:windowNoTitle">true</item>
    <item name="android:background">@android:color/transparent</item>
    <!-- 背景透明 -->
    <item name="android:windowBackground">@android:color/transparent</item>
    <!-- 模糊 -->
    <item name="android:backgroundDimEnabled">true</item>
    <!-- 遮罩层 -->
    <item name="android:backgroundDimAmount">0.5</item>
</style>

<!-- dialog的动画 -->
<style name="main_menu_animStyle">
    <item name="android:windowEnterAnimation">@anim/dialog_in_anim</item>
    <item name="android:windowExitAnimation">@anim/dialog_out_anim</item>
</style>

Implementation

 mainActivity.xml:

void showBottomDialog Private () { 
    //. 1, use Dialog, set the style 
    Final = new new Dialog Dialog Dialog (the this, R.style.DialogTheme); 
    // 2, set the layout 
    View view = View.inflate (this, R.layout . Dialog, null); 
    dialog.setContentView (View); 

    the window window dialog.getWindow = (); 
    // set the eject position 
    window.setGravity (Gravity.BOTTOM); 
    // set the animation pop 
    window.setWindowAnimations (R.style.main_menu_animStyle) ; 
    // set the size of the dialog 
    window.setLayout (ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT); 
    with dialog.show (); 

    dialog.findViewById (R.id.tv_take_photo) .setOnClickListener (new new View.OnClickListener () { 
        @Override
        public void onClick(View view) {
            dialog.dismiss();
        }
    });

    dialog.findViewById(R.id.tv_take_pic).setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            dialog.dismiss();
        }
    });

    dialog.findViewById(R.id.tv_cancel).setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            dialog.dismiss();
        }
    });

}
完成




也可以封装成方法：

showBottomDialog.class:

{class showBottomDialog public 
    Private View View; 
    public void BottomDialog (the Context context) { 
        //. 1, use Dialog, set the style 
        Final new new Dialog Dialog Dialog = (context, R.style.DialogTheme); 
        // 2, set the layout 
        view = View .inflate (context, R.layout.dialog, null); 
        dialog.setContentView (View); 

        the window window dialog.getWindow = (); 
        // set the eject position 
        window.setGravity (Gravity.BOTTOM); 
        // set pop animation 
        window .setWindowAnimations (R.style.main_menu_animStyle); 
        // set the size of the dialog 
        window.setLayout (ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT); 
        with dialog.show ();

        dialog.findViewById(R.id.tv_take_photo).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                dialog.dismiss();
            }
        });

        dialog.findViewById(R.id.tv_take_pic).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                dialog.dismiss();
            }
        });

        dialog.findViewById(R.id.tv_cancel).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                dialog.dismiss();
            }
        }); 
    } 
}
