谷歌地图Android的API V2 - 检测触摸地图 [英] google maps android api v2 - detect touch on map

问题描述

我无法找到如何拦截新的地图API V2地图上触摸的例子。

I can't find an example on how to intercept the map touch on new maps api v2.

我要当用户触摸地图，以阻止一个线程（在我的当前位置在地图的定心）就知道了。 请给我一个起点。 谢谢你。

I need to know when user touches the map in order to stop a thread (the centering of the map around my current location). Please, give me a starting point. Thank you.

@ape这里写一篇关于如何拦截地图上点击一个答案，但我需要截取的接触，那么他建议在评论下面的链接它回答<一href="http://stackoverflow.com/questions/13722869/how-to-handle-ontouch-event-for-map-in-google-map-api-v2">How要在地图在谷歌地图API V2处理onTouch事件？

@ape wrote here an answer on how to intercept the map clicks, but i need to intercept the touches, then he suggested the following link in a comment of its answer How to handle onTouch event for map in Google Map API v2?

该解决方案似乎是一个可能的解决方法，但建议code是不完整的。 出于这个原因，我重写，并对其进行了测试。 现在，它的工作原理。 这是工作code：

That solution seems to be a possible workaround but the suggested code was incomplete. For this reason I rewrote and tested it. Now it works. Here it is the working code:

我创建的类MySupportMapFragment.java

I created the class MySupportMapFragment.java

import com.google.android.gms.maps.SupportMapFragment;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

public class MySupportMapFragment extends SupportMapFragment {
  public View mOriginalContentView;
  public TouchableWrapper mTouchView;   

  @Override
  public View onCreateView(LayoutInflater inflater, ViewGroup parent, Bundle savedInstanceState) {
    mOriginalContentView = super.onCreateView(inflater, parent, savedInstanceState);    
    mTouchView = new TouchableWrapper(getActivity());
    mTouchView.addView(mOriginalContentView);
    return mTouchView;
  }

  @Override
  public View getView() {
    return mOriginalContentView;
  }
}

我甚至创建的类TouchableWrapper.java：

I even created the class TouchableWrapper.java:

import android.content.Context;
import android.view.MotionEvent;
import android.widget.FrameLayout;

public class TouchableWrapper extends FrameLayout {

  public TouchableWrapper(Context context) {
    super(context);
  }

  @Override
  public boolean dispatchTouchEvent(MotionEvent event) {
    switch (event.getAction()) {
      case MotionEvent.ACTION_DOWN:
            MainActivity.mMapIsTouched = true;
            break;
      case MotionEvent.ACTION_UP:
            MainActivity.mMapIsTouched = false;
            break;
    }
    return super.dispatchTouchEvent(event);
  }
}

在布局中我宣布它是这样的：

in the layout i declare it this way:

<fragment xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/mapFragment"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:layout_below="@+id/buttonBar"
    class="com.myFactory.myApp.MySupportMapFragment"
/>

只是为了测试主要活动我只写了以下内容：

Just for test in main Activity i wrote only the following:

public class MainActivity extends FragmentActivity {
  public static boolean mMapIsTouched = false;

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
  }
}
