Question

我有一个有趣的问题。当用户接到电话时，我会向他们显示一个文本，我正在使用TYPE_SYSTEM_OVERLAY进行调用。但在锁定屏幕上会出现第二个窗口！ Here's the image of the issue I'm having.

谢谢，

这是我的代码：

final WindowManager.LayoutParams params = new WindowManager.LayoutParams(
    ViewGroup.LayoutParams.MATCH_PARENT,
    ViewGroup.LayoutParams.WRAP_CONTENT,
    WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY,
    WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE,
    PixelFormat.TRANSLUCENT
);
params.height = 150;
params.gravity = Gravity.CLIP_HORIZONTAL | Gravity.CENTER;
nm.this.getWindow().setAttributes(params);
WindowManager wm = (WindowManager) getApplicationContext().getSystemService(WINDOW_SERVICE);
TextView tv = new TextView (nm.this);
tv.setText ("Showing the error");
LinearLayout lo = new LinearLayout(nm.this);
lo.setOrientation(LinearLayout.VERTICAL);
lo.addView(tv);
wm.addView (lo, params);

我的清单文件：

    <activity
        android:name=".nm"
        android:theme="@android:style/Theme.DeviceDefault.Dialog.NoActionBar"
        android:label="@string/title_activity_nm" >
    </activity>

Android TYPE_SYSTEM_OVERLAY删除第二个窗口
