b: theme code, it should be noted that activity must be inherited, otherwise a theme error will be reported

  <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.Light">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
    </style>
    <!--activity 透明-淡入淡出-->
    <style name="activity_translucent" parent="Theme.AppCompat.Dialog">
        <item name="windowActionBar">false</item>
        <item name="windowActionBarOverlay">false</item>
        <item name="android:windowAnimationStyle">@style/AnimBottom</item>
        <item name="windowActionModeOverlay">false</item>
        <!-- 边框 -->
        <item name="android:windowFrame">@null</item>
        <!-- 是否浮现在activity之上 -->
        <item name="android:windowIsFloating">false</item>

        <!--背景变暗-->
        <item name="android:backgroundDimEnabled">true</item>
    </style>

c manifest.xml file

  <activity android:name=".MainActivity"
            android:theme="@style/Theme.AppCompat.Light">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity android:name=".DialogFullActivity"
            android:configChanges="keyboardHidden|orientation|screenSize"
            android:theme="@style/activity_translucent"
            />

d: activity code, the onFinish method must be rewritten to reset the exit animation

package com.cn.wq.dialog;

import android.app.Activity;
import android.os.Bundle;

public class DialogFullActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_dialog_full);
    }
    @Override
    public void finish() {
        super.finish();
        overridePendingTransition(0, R.anim.push_bottom_out);
    }

}
