Simple Method to Set Activity Background to Transparent Style in Android (Must Read)

Method 1:

Through Theme.Translucent

@android:style/Theme.Translucent
@android:style/Theme.Translucent.NoTitleBar
@android:style/Theme.Translucent.NoTitleBar.Fullscreen

Only set the theme to any of the above in the transparent Activity that is needed in the Manifest

<activity 
  android:name="com.vixtel.simulate.MainApp" 
  android:configChanges="keyboardHidden|orientation" 
  android:label="@string/app_name" 
  android:screenOrientation="portrait" 
  android:theme="@android:style/Theme.Translucent.NoTitleBar" > 
  <intent-filter> 
    <action android:name="android.intent.action.MAIN" /> 
    <category android:name="android.intent.category.LAUNCHER"}} /> 
  </intent-filter> 
</activity> 

Method Two:

Custom style, just like custom Dialog style, in res-values-color.xml, add the transparent color value:

<?xml version="1.0" encoding="UTF-8"?> 
<resources> 
  <color name="transparent">#0000</color> 
</resources> 

In res-values-Add the following to styles.xml:

<style name="myTransparent"> 
  <item name="android:windowBackground">@color/transparent</item> 
  <item name="android:windowNoTitle">true</item> 
  <item name="android:windowIsTranslucent">true</item> 
  <item name="android:windowAnimationStyle">@android:style/Animation.Translucent</item> 
</style> 

In the Manifest, set the theme of the Activity that needs to be transparent to our custom theme

android:theme="@style/myTransparent"

After running the program, it becomes completely transparent, and everything under the background can be seen, but all operations are invalid.
