兩個開發中常用到的

1.dialog主題的Activity

   <style name="myDialogTheme" parent="Theme.AppCompat.Dialog">
        <item name="android:windowFrame">@null</item>
        <item name="android:windowIsFloating">true</item>
        <item name="android:windowIsTranslucent">false</item>
        <item name="android:windowNoTitle">true</item><!--除去title-->
        <item name="android:windowContentOverlay">@null</item>
        <item name="android:backgroundDimEnabled">false</item>
        <item name="android:screenOrientation">portrait</item>
        <item name="android:windowBackground">@null</item><!--除去背景色-->
    </style>

2.singleInstance模式下activity切換動畫問題

將所有的activity都設置動畫，覆蓋掉默認的：

<style name="NoTitleBar" parent="android:Theme.Light.NoTitleBar">
    <item name="android:windowAnimationStyle">@style/AnimationActivity</item>
</style>

切換動畫：

<style name="AnimationActivity" parent="@android:style/Animation.Activity" >
    <item name="android:activityOpenEnterAnimation">@anim/slide_right_in</item>
    <item name="android:activityOpenExitAnimation">@anim/slide_left_out</item>
    <item name="android:activityCloseEnterAnimation">@anim/slide_left_in</item>
    <item name="android:activityCloseExitAnimation">@anim/slide_right_out</item>
</style>

這隻完成了對正常activity的操作動畫
進入到singleInstance的activi中時，進入activity加入：

overridePendingTransition(R.anim.slide_right_in, R.anim.slide_left_out);//注意順序不能交換

銷燬activity:

    @Click({R.id.back, R.id.tv})
    void back() {
        finish();
        overridePendingTransition(R.anim.slide_left_in, R.anim.slide_right_out);
    }

    @Override
    public void onBackPressed() {
        super.onBackPressed();
        overridePendingTransition(R.anim.slide_left_in, R.anim.slide_right_out);
    }

slide_left_in.xml:

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >
    <translate
        android:duration="400"
        android:fromXDelta="-100.0%p"
        android:toXDelta="0.0" />
</set> 

slide_left_out.xml:

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <translate
        android:duration="400"
        android:fromXDelta="0.0"
        android:toXDelta="-100.0%p" />
</set> 

slide_right_in.xml:

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >
    <translate
        android:duration="400"
        android:fromXDelta="100.0%p"
        android:toXDelta="0.0" />
</set>

slide_right_out.xml:

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >
    <translate
        android:duration="400"
        android:fromXDelta="0.0"
        android:toXDelta="100.0%p" />
</set>
