运行时使用 appcompat 覆盖 android

Question

我想为使用 appcompat 的应用程序制作运行时覆盖，但我无法让它工作。

\n

我按照这个例子

\n

首先：\n我创建了我想要覆盖的 Android 应用程序。我正在尝试将文本视图“Hello World”中的字符串覆盖为“Hello World override!”

\n

应用程序代码快照

\n

主要活动：

\n

class MainActivity : AppCompatActivity() {\n    override fun onCreate(savedInstanceState: Bundle?) {\n        super.onCreate(savedInstanceState)\n        setContentView(R.layout.activity_main)\n    }\n}\n

\n

主要活动布局：

\n

<?xml version="1.0" encoding="utf-8"?>\n<FrameLayout\n\xc2\xa0xmlns:android="http://schemas.android.com/apk/res/android"\n\xc2\xa0xmlns:app="http://schemas.android.com/apk/res-auto"\n\xc2\xa0xmlns:tools="http://schemas.android.com/tools"\n\xc2\xa0android:layout_width="match_parent"\n\xc2\xa0android:layout_height="match_parent"\n\xc2\xa0tools:context=".MainActivity">\n\n\xc2\xa0<TextView\n\xc2\xa0android:layout_width="wrap_content"\n\xc2\xa0android:layout_height="wrap_content"\n\xc2\xa0android:text="@string/hello_world"\n\xc2\xa0/>\n\n</FrameLayout>\n

\n

显现：

\n

<?xml version="1.0" encoding="utf-8"?>\n<manifest xmlns:android="http://schemas.android.com/apk/res/android"\n\xc2\xa0xmlns:tools="http://schemas.android.com/tools"\n\xc2\xa0package="com.example.app">\n\n\xc2\xa0<application\n\xc2\xa0 \xc2\xa0 \xc2\xa0android:allowBackup="true"\n\xc2\xa0 \xc2\xa0 \xc2\xa0android:icon="@mipmap/ic_launcher"\n\xc2\xa0 \xc2\xa0 \xc2\xa0android:label="@string/app_name"\n\xc2\xa0 \xc2\xa0 \xc2\xa0android:roundIcon="@mipmap/ic_launcher_round"\n     android:theme="@style/MyTheme"\n\xc2\xa0 \xc2\xa0 \xc2\xa0android:supportsRtl="true">\n\xc2\xa0 \xc2\xa0 \xc2\xa0<activity android:name=".MainActivity">\n\xc2\xa0 \xc2\xa0 \xc2\xa0 \xc2\xa0<intent-filter>\n\xc2\xa0 \xc2\xa0 \xc2\xa0 \xc2\xa0 \xc2\xa0<action android:name="android.intent.action.MAIN"/>\n\xc2\xa0 \xc2\xa0 \xc2\xa0 \xc2\xa0 \xc2\xa0<category android:name="android.intent.category.LAUNCHER"/>\n\xc2\xa0 \xc2\xa0 \xc2\xa0 \xc2\xa0</intent-filter>\n\xc2\xa0 \xc2\xa0 \xc2\xa0</activity>\n\xc2\xa0</application>\n\n</manifest>\n

\n

应用主题：

\n

\n    <style name="MyTheme" parent="Theme.AppCompat.Light.NoActionBar">\n        <!-- Customize your theme here. -->\n        <item name="colorPrimary">@color/colorPrimary</item>\n        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>\n        <item name="colorAccent">@color/colorAccent</item>\n    </style>\n\n

\n

字符串资源

\n

    <string name="hello_world">Hello World!</string>\n

\n

到目前为止，代码运行良好:)

\n

然后我创建包含覆盖资源的覆盖项目。

\n

Overlay项目代码截图：

\n

显现：

\n

<manifest xmlns:android="http://schemas.android.com/apk/res/android"\n          package="com.example.overlay">\n\n    <overlay\n        android:priority="1"\n        android:targetPackage="com.example.app"/>\n    <application android:hasCode="false"/>\n\n</manifest>\n

\n

我想在运行时覆盖它们的字符串资源

\n

    <string name="hello_world">Hello World Overlay!</string>\n

\n

我构建并安装了 apk。当我使用时我可以找到它作为覆盖 adb shell cmd overlay list

\n

一旦我启用了覆盖，adb shell cmd overlay enable --user 0 com.example.overlay我就遇到了这个崩溃。

\n

\n

但是，我在应用程序和覆盖层上使用 appcompat 主题。

\n

有什么想法可以让它发挥作用吗？

\n

注意：我尝试在 Android 9 和 Android 10 上运行它

\n

更新 1：\n当我从 Activity 而不是 AppCompatActivity 扩展时，它工作正常，没有任何问题

您可以在那里使用我的库，我尝试以一种非常可重用的方式做到这一点，以便您可以使用更少的代码进行覆盖。这是有关如何在Java和Kotlin中使用它的文档。首先，从要显示水印的活动中初始化它 -

AppWaterMarkBuilder.doConfigure()
                .setAppCompatActivity(MainActivity.this)
                .setWatermarkProperty(R.layout.layout_water_mark)
                .showWatermarkAfterConfig();

然后您可以从应用程序中的任何位置隐藏和显示它 -

  /* For hiding the watermark*/
  AppWaterMarkBuilder.hideWatermark() 

  /* For showing the watermark*/
  AppWaterMarkBuilder.showWatermark()
