两个开发中常用到的

1.dialog主题的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切换动画问题

将所有的activity都设置动画，覆盖掉默认的：

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

切换动画：

<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>

这只完成了对正常activity的操作动画

进入到singleInstance的activi中时，进入activity加入：

overridePendingTransition(R.anim.slide_right_in, R.anim.slide_left_out);//注意顺序不能交换

销毁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
