嘿,所以我想在Android中创建一个具有覆盖按钮的应用程序,并对手机上的每个应用程序进行截图(如果单击覆盖按钮)(除了使用FLAG_SECURE之外的任何内容)。我知道这是可能的,因为这个应用实际上是这样做的:https://play.google.com/store/apps/details?id=com.tools.screenshot
那么有谁知道一个允许我做这个截图的代码示例? 我已经有了叠加按钮,所以只需要截屏代码。感谢
答案 0 :(得分:0)
答案太宽泛,但是从旧博客那里得到了这个:
taking_screenshot_in_android.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/layout"
android:layout_width="fill_parent"

try {

FileOutputStream outputStream = new FileOutputStream(file);
outputStream.write(bytes.toByteArray());
outputStream.close();
} catch (Exception e) {
e.printStackTrace();
}
}
}
的strings.xml
<string name="app_name">Taking Screenshot in Android Programmatically</string>
输出:
