对话锁定来电屏幕

Question

我希望对话框和来电屏幕都可以点击。我已经从该站点尝试过不同的解决方案，但有些在某些条件下有效，而另一些则无效。我想创建一个像 true caller 这样的应用程序，我从 BroadcastReceiver 调用了一个 activity。当屏幕未锁定时，我的代码可以完美运行，因为传入屏幕不是全屏。但是当屏幕全屏时，对话框 activity 在调用屏幕上出现几毫秒，然后在调用屏幕后面。

这是我从 BroadcastReceiver

调用的 activity 代码

public class IncomingCallActivity extends AppCompatActivity {

private static final int MSG_ID_CHECK_TOP_ACTIVITY = 1;

private String userName;
private String TAG = IncomingCallActivity.class.getSimpleName();
private Window wind;

private PowerManager powerManager;
private PowerManager.WakeLock wakeLock;

/*private ActivityManager mActivityManager;
private boolean mDismissed = false;*/

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    wind = this.getWindow();
    wind.requestFeature(Window.FEATURE_NO_TITLE);
    wind.addFlags(WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD);
    wind.addFlags(WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED);
    wind.addFlags(WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON);
    wind.addFlags(WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL);

    powerManager = (PowerManager)getSystemService(Context.POWER_SERVICE);
    wakeLock = powerManager.newWakeLock(PowerManager.FULL_WAKE_LOCK, "My Lock");
    wakeLock.acquire();

    setContentView(R.layout.activity_incoming_call);
    userName = getIntent().getStringExtra(IncomingCallReceiver.NAME_KEY);

    final TextView textView = (TextView) findViewById(R.id.tvUsername);
    textView.setText(userName);

    final ImageView ivCancel = (ImageView) findViewById(R.id.ivCancel);
    ivCancel.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            wakeLock.release();
            IncomingCallActivity.this.finish();
        }
    });

}

}

     //Add Permissions in Manifest file and don't forget to check overlay permission
            <uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW"/>
            <uses-permission android:name="android.permission.SYSTEM_OVERLAY_WINDOW"/>

     //Create Class Level Variable  or as per requirement 

                WindowManager.LayoutParams mWindowsParams;
                WindowManager mWindowManager;
                View mDialogView;

    //initialize variable
 mWindowsParams =new WindowManager.LayoutParams(WindowManager.LayoutParams.MATCH_PARENT,
                                    WindowManager.LayoutParams.WRAP_CONTENT,
                                    WindowManager.LayoutParams.TYPE_SYSTEM_ERROR,
                                    WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE,
                                    PixelFormat.TRANSLUCENT);
mWindowManager=(WindowManager)context.getSystemService(Context.WINDOW_SERVICE);

//Add Window on your event
 mWindowManager.addView(mDialogView, mWindowsParams);

//For Remove window

 if (mDialogView.getParent() != null) {
      try {
          mWindowManager.removeViewImmediate(mDialogView);
            } catch (Exception e) {
