Question

我有这个布局，在清单中，我放置了行android:icon="@drawable/ic_launcher"，但是没有显示应用图标......

布局内容：

<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>

Manifest的内容：

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

    <!-- Include required permissions for Google Mobile Ads to run-->

您的manifest结构应该与Android Studio

类似

 <?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>

注意：对于透明背景，您应该使用

android:style/Theme.Translucent

并重新命名所有的java类名称（以大写字母开头..）

应用程序图标丢失/没有出现在android studio中
