2: 问题原因

项目需求,由原来的targetSdkVersion 24 升级到了28.

3: 源码

private void showOff() {
    WindowManager.LayoutParams params = new WindowManager.LayoutParams();
    params.gravity = Gravity.CENTER_HORIZONTAL | Gravity.BOTTOM;
    params.height = WindowManager.LayoutParams.WRAP_CONTENT;
    params.width = WindowManager.LayoutParams.WRAP_CONTENT;
    params.flags = WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE | WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE;
    params.format = PixelFormat.TRANSLUCENT;
    params.windowAnimations = android.R.style.Animation_Toast;
    params.y = dip2px(mContext, 64);
    if (Build.VERSION.SDK_INT > 24) {
        params.type = WindowManager.LayoutParams.TYPE_PHONE;
    } else {
        params.type = WindowManager.LayoutParams.TYPE_TOAST;
    }
    try {
        mFloatView = getView(mContext, text);
        mFloatView.setLayoutParams(params);
        WindowManager manager = (WindowManager) mContext.getSystemService(Context.WINDOW_SERVICE);
        manager.addView(mFloatView, params);
    } catch (Throwable e) {
        e.printStackTrace();
    }
}

4: 解决办法

需要适配Build.VERSION_CODES.O:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
    params.type = WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY;
}else if (Build.VERSION.SDK_INT > 24) {
    params.type = WindowManager.LayoutParams.TYPE_PHONE;
} else {
    params.type = WindowManager.LayoutParams.TYPE_TOAST;
}
