准备
- 准备进入和退出动画../res/anim
a. push_bottom_in.xml
<?xml version="1.0" encoding="utf-8"?>
<!-- 上下滑入式 -->
<set xmlns:android="http://schemas.android.com/apk/res/android" >
<translate
android:duration="200"
android:fromYDelta="50%p"
android:toYDelta="0" />
</set>
b. push_bottom_out.xml
<?xml version="1.0" encoding="utf-8"?><!-- 上下滑入式 -->
<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate
android:duration="200"
android:fromYDelta="0"
android:toYDelta="50%p" />
</set>
c. 在 thems.xml 中使用
<style name="AnimUp" parent="@android:style/Animation">
<item name="android:windowEnterAnimation">@anim/push_bottom_in</item>
<item name="android:windowExitAnimation">@anim/push_bottom_out</item>
</style>
- layout 背景 dialog_bg_normal.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<corners android:radius="10dp"/>
<solid android:color="@color/white"/>
<stroke android:color="#cbcbcb" android:width="1px"/>
</shape>
- 工具类 CommonUtil.java
/**

* @author Gong Youqiang
*/
public class CommonUtil {
/**
* 测量View的宽高
*
* @param view View
*/
public static void measureWidthAndHeight(View view) {
int w = View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED);
int h = View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED);
view.measure(w, h);
}
public static String getJsonStringByEntity(Object o) {
String strJson = "";
Gson gson = new Gson();
strJson = gson.toJson(o);
return strJson;
}
}
实现
- 布局文件 popup_take_photo.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@drawable/dialog_bg_normal"
android:layout_marginLeft="20dp"
android:layout_marginRight="20dp"
android:orientation="vertical">
<TextView
android:id="@+id/tv_avatar_photograph"
android:layout_width="match_parent"
android:layout_height="45dp"
android:textSize="16sp"
android:gravity="center"
android:textColor="@color/text_color"
android:text="拍照"/>
<View
android:layout_width="match_parent"
android:layout_height="0.5dp"
android:background="@color/divider"/>
<TextView
android:id="@+id/tv_avatar_photo"
android:layout_width="match_parent"
android:layout_height="45dp"
android:textSize="16sp"
android:gravity="center"
android:textColor="@color/text_color"
