的應用程序圖標丟失/不出現機器人工作室

Question

我有這樣的佈局，並在清單中，我把線android:icon="@drawable/ic_launcher"，但不顯示的應用程序圖標...

佈局的內容：

<RelativeLayout 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:paddingLeft="@dimen/activity_horizontal_margin" 
    android:paddingRight="@dimen/activity_horizontal_margin" 
    android:paddingTop="@dimen/activity_vertical_margin" 
    android:paddingBottom="@dimen/activity_vertical_margin" 
    tools:context=".java0" 
    tools:ignore="MergeRootFrame" 
    android:screenOrientation="portrait" 
    android:icon="@drawable/ic_launcher" 
    android:background="#ffff7e00"> 
</RelativeLayout> 

清單的內容：

<?xml version="1.0" encoding="utf-8"?> 
<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
    package="theapp.application.app.theapp" >

您manifest結構應該像Android Studio

<?xml version="1.0" encoding="utf-8"?> 
     <manifest xmlns:android="http://schemas.android.com/apk/res/android" 
        package="com.org.yourpackage" > 
     <application 
     android:allowBackup="true" 
      android:icon="@drawable/ic_launcher" 
      android:label="@string/app_name" 
      android:theme="@style/AppTheme" > 
      <activity 
       android:name=".YourStartingActivity" 
       android:label="@string/app_name" > 
       <intent-filter> 
        <action android:name="android.intent.action.MAIN" /> 
        <category android:name="android.intent.category.LAUNCHER" /> 
       </intent-filter> 
      </activity> 

     </application> 

    </manifest> 

注：透明背景你應該使用

android:style/Theme.Translucent 

，並就重命名你所有的Java類名（含上限開始吧..）
