Android Can'；t单击作为覆盖的视图下的按钮

我正在开发一个应用程序，它在屏幕上叠加了一个视图，作为屏幕上的一种色调。我已经得到了我想要的颜色的视图，我可以看到它后面的按钮。。问题是我无法单击它们！：(

以下是该应用程序在屏幕上实现的效果（这是我想要的外观）：

import android.app.Service;
import android.content.Intent;
import android.graphics.Color;
import android.graphics.PixelFormat;
import android.os.IBinder;
import android.view.Gravity;
import android.view.View;
import android.view.WindowManager;

public class OverlayService extends Service {
    private WindowManager windowManager;
    private View filter;

    @Override
    public IBinder onBind(Intent intent) {
        // Not used
        return null;
    }

    @Override public void onCreate() {
    super.onCreate();

    windowManager = (WindowManager) getSystemService(WINDOW_SERVICE);

    filter = new View(this); // Create a new view
    float alpha = (float) 0.8; // Create alpha variable
    filter.setAlpha(alpha); // Set alpha (this doesn't seem to do anything)
    filter.setBackgroundColor(Color.YELLOW); // Set the background colour to yellow
    filter.getBackground().setAlpha(80); // Set the background's alpha (this is the call that works!)

    WindowManager.LayoutParams params = new WindowManager.LayoutParams(
        WindowManager.LayoutParams.WRAP_CONTENT,
        WindowManager.LayoutParams.WRAP_CONTENT,
        WindowManager.LayoutParams.TYPE_PHONE,
        WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE,
        PixelFormat.TRANSLUCENT);

    params.gravity = Gravity.TOP | Gravity.LEFT;
    params.x = 0;
    params.y = 100;

    windowManager.addView(filter, params);
  }

  @Override
  public void onDestroy() {
    super.onDestroy();
    if (filter != null) windowManager.removeView(filter); // If the filter exists, remove it
  }

}

WindowManager.LayoutParams params = new WindowManager.LayoutParams(
        WindowManager.LayoutParams.WRAP_CONTENT,
        WindowManager.LayoutParams.WRAP_CONTENT,
        WindowManager.LayoutParams.TYPE_PHONE,
        WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE, // This line changed!
        PixelFormat.TRANSLUCENT);

我的代码：

import android.app.Service;
import android.content.Intent;
import android.graphics.Color;
import android.graphics.PixelFormat;
import android.os.IBinder;
import android.view.Gravity;
import android.view.View;
import android.view.WindowManager;

public class OverlayService extends Service {
    private WindowManager windowManager;
    private View filter;

    @Override
    public IBinder onBind(Intent intent) {
        // Not used
        return null;
    }

    @Override public void onCreate() {
    super.onCreate();

    windowManager = (WindowManager) getSystemService(WINDOW_SERVICE);

    filter = new View(this); // Create a new view
    float alpha = (float) 0.8; // Create alpha variable
    filter.setAlpha(alpha); // Set alpha (this doesn't seem to do anything)
    filter.setBackgroundColor(Color.YELLOW); // Set the background colour to yellow
    filter.getBackground().setAlpha(80); // Set the background's alpha (this is the call that works!)

    WindowManager.LayoutParams params = new WindowManager.LayoutParams(
        WindowManager.LayoutParams.WRAP_CONTENT,
        WindowManager.LayoutParams.WRAP_CONTENT,
        WindowManager.LayoutParams.TYPE_PHONE,
        WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE,
        PixelFormat.TRANSLUCENT);

    params.gravity = Gravity.TOP | Gravity.LEFT;
    params.x = 0;
    params.y = 100;

    windowManager.addView(filter, params);
  }

  @Override
  public void onDestroy() {
    super.onDestroy();
    if (filter != null) windowManager.removeView(filter); // If the filter exists, remove it
  }

}

WindowManager.LayoutParams params = new WindowManager.LayoutParams(
        WindowManager.LayoutParams.WRAP_CONTENT,
        WindowManager.LayoutParams.WRAP_CONTENT,
        WindowManager.LayoutParams.TYPE_PHONE,
        WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE, // This line changed!
        PixelFormat.TRANSLUCENT);

干杯！

将WindowManager布局参数更改为：

import android.app.Service;
import android.content.Intent;
import android.graphics.Color;
import android.graphics.PixelFormat;
import android.os.IBinder;
import android.view.Gravity;
import android.view.View;
import android.view.WindowManager;

public class OverlayService extends Service {
    private WindowManager windowManager;
    private View filter;

    @Override
    public IBinder onBind(Intent intent) {
        // Not used
        return null;
    }

    @Override public void onCreate() {
    super.onCreate();

    windowManager = (WindowManager) getSystemService(WINDOW_SERVICE);

    filter = new View(this); // Create a new view
    float alpha = (float) 0.8; // Create alpha variable
    filter.setAlpha(alpha); // Set alpha (this doesn't seem to do anything)
    filter.setBackgroundColor(Color.YELLOW); // Set the background colour to yellow
    filter.getBackground().setAlpha(80); // Set the background's alpha (this is the call that works!)

    WindowManager.LayoutParams params = new WindowManager.LayoutParams(
        WindowManager.LayoutParams.WRAP_CONTENT,
        WindowManager.LayoutParams.WRAP_CONTENT,
        WindowManager.LayoutParams.TYPE_PHONE,
        WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE,
        PixelFormat.TRANSLUCENT);

    params.gravity = Gravity.TOP | Gravity.LEFT;
    params.x = 0;
    params.y = 100;

    windowManager.addView(filter, params);
  }

  @Override
  public void onDestroy() {
    super.onDestroy();
    if (filter != null) windowManager.removeView(filter); // If the filter exists, remove it
  }

}

WindowManager.LayoutParams params = new WindowManager.LayoutParams(
        WindowManager.LayoutParams.WRAP_CONTENT,
        WindowManager.LayoutParams.WRAP_CONTENT,
        WindowManager.LayoutParams.TYPE_PHONE,
        WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE, // This line changed!
        PixelFormat.TRANSLUCENT);

多亏了@DeeV:）

我不确定，但是您是否已经尝试覆盖'onInterceptTouchEvent'以返回'filter'-视图的false？在layoutparams中，您应该包括“FLAG_not_TOUCHABLE”。@Aleksandrmedvedevev该视图（超类）没有名为

onInterceptTouchEvent

的方法@DeeV！非常感谢。这不起作用Marshmallow我不确定，但您是否已经尝试覆盖“onInterceptTouchEvent”以返回“filter”视图的false？在layoutparams中，您应该包括“FLAG\u not\u TOUCHABLE”。@AleksandrMedvedev视图（超类）没有名为

onInterceptTouchEvent

@DeeV brilliant fixed！非常感谢。这不适用于Marshmallow在我创建的新AVD上，覆盖右侧被切断，这是通过将第一个参数更改为

WindowManager.LayoutParams.MATCH\u PARENT

而不是

WindowManager.LayoutParams.WRAP\u CONTENT

来修复的。在新AVD上，我创建的覆盖右侧被切断，通过将第一个参数更改为

WindowManager.LayoutParams.MATCH_PARENT

而不是

WindowManager.LayoutParams.WRAP_CONTENT

，可以解决此问题。
