Question

我正在尝试从整个屏幕的后台辅助功能服务中截取屏幕截图，我尝试从当前应用程序上绘制的服务中插入一个视图，然后尝试使用它来实现。但我得到了什么只是我的黑色背景视图。感谢任何帮助，谢谢：D

public void addView() {
    WindowManager windowManager = (WindowManager) getSystemService(WINDOW_SERVICE);
    LayoutInflater inflater = (LayoutInflater) getSystemService(LAYOUT_INFLATER_SERVICE);


    if (layout != null) {
        windowManager.removeViewImmediate(layout);

    } else {
        layout = (RelativeLayout) inflater.inflate(R.layout.hoock_layout, null);
        layout.setDrawingCacheEnabled(true);
    }

    WindowManager.LayoutParams params = new WindowManager.LayoutParams(WindowManager.LayoutParams.WRAP_CONTENT, WindowManager.LayoutParams.WRAP_CONTENT, WindowManager.LayoutParams.TYPE_SYSTEM_ALERT, WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE | WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL, PixelFormat.TRANSLUCENT);
    params.gravity = Gravity.LEFT | Gravity.TOP;
    params.x = 0;
    params.y = 0;
    windowManager.addView(layout, params);

    store(getScreenShot(layout), "TEST.png");
}

public Bitmap getScreenShot（View view）{

    View screenView = view.getRootView();
    screenView.setDrawingCacheEnabled(true);


    screenView.measure(View.MeasureSpec.makeMeasureSpec(1500, View.MeasureSpec.UNSPECIFIED),
            View.MeasureSpec.makeMeasureSpec(1800, View.MeasureSpec.UNSPECIFIED));
    screenView.layout(0, 0, screenView.getMeasuredWidth(), screenView.getMeasuredHeight());

    screenView.buildDrawingCache(true);
    screenView.setDrawingCacheEnabled(true);
    Bitmap bitmap = Bitmap.createBitmap(screenView.getDrawingCache());
    return bitmap;
}


public void store(Bitmap bm, String fileName) {
    final String dirPath = Environment.getExternalStorageDirectory().getAbsolutePath() + "/AccessibilityPOF";
    File dir = new File(dirPath);
    if (!dir.exists())
        dir.mkdirs();
    File file = new File(dirPath, fileName);
    try {


        FileOutputStream fOut = new FileOutputStream(file);
        bm.compress(Bitmap.CompressFormat.PNG, 85, fOut);
        fOut.flush();
        fOut.close();
    } catch (Exception e) {
        e.printStackTrace();
    }
}
