说明

manifestPlaceholders

它可以在 build.gradle文件中定义字符串并将值映射到 AndroidManifest清单文件的指定位置

AndroidManifest 文件定义占位符

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN"/>
                <category android:name="android.intent.category.LAUNCHER"/>
            </intent-filter>
            
            // 这是在Activity 标签下
            <meta-data android:name="nameActivity" android:value="${test_value_activity}"/>
        </activity>
        
         // 这是在Activity 标签下
        <meta-data android:name="nameApplication" android:value="headword${test_value}append_word"/>
    </application>

build.gradle 给占位符赋值

defaultConfig {
        applicationId "com.didikee.wififriend"
        minSdkVersion 15
        targetSdkVersion 24
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        manifestPlaceholders = [test_value: "这是测试值",test_value_activity:"Activity 中的测试值"]
    }

在Java代码获取占位符的值

        ActivityInfo activityInfo = null;
        ApplicationInfo applicationInfo = null;
        ServiceInfo serviceInfo = null;
        ActivityInfo receiverInfo = null;
        try {
            activityInfo = context.getPackageManager().getActivityInfo(activity.getComponentName(), PackageManager.GET_META_DATA);
            applicationInfo = context.getPackageManager().getApplicationInfo(activity.getPackageName(), PackageManager.GET_META_DATA);
            serviceInfo = context.getPackageManager().getServiceInfo(activity.getComponentName(), PackageManager.GET_META_DATA);
            receiverInfo = context.getPackageManager().getReceiverInfo(activity.getComponentName(), PackageManager.GET_META_DATA);
        } catch (PackageManager.NameNotFoundException e) {
            e.printStackTrace();
        }
        activityInfo.metaData.getString("nameActivity");
        applicationInfo.metaData.getString("nameApplication") ;
