Question

我试图将jetpack compose视图添加到窗口管理器以获取App覆盖视图。但是该应用程序崩溃了。我已经使用以下代码来添加jetpack撰写视图。当我尝试XML布局时，它工作正常。还有其他人遇到这个问题吗？预先感谢。

private val overlayWindowManager by lazy {
    getSystemService(Context.WINDOW_SERVICE)
            as WindowManager
}

 private fun initWindowManager() {
    val params = WindowManager.LayoutParams(
        WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY,
        WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH,
        PixelFormat.TRANSLUCENT
    )
    params.gravity = Gravity.RIGHT or Gravity.TOP
    overlayWindowManager.addView(ComposeView(this).apply {
        setContent {  Text("WINDOW") }
    }, params)
}

Answer 1

您的主要活动延伸到哪个班级？看起来您的答案在堆栈跟踪的第一行 Use ComponentActivity, FragmentActivity or AppCompatActivity to configure ViewTreeLifecycleOwner automatically

或

call ViewTreeLifecycleOwner.set() for this View or an ancestor in the same window

Answer 2

使用ViewTreeLifecycleOwner.set()：

windowManager.addView(ComposeView(this).apply {
    ViewTreeLifecycleOwner.set(this, activity)
    setContent {  Text("WINDOW") }
}, params)
