如何进去onTouchEvent（MotionEvent事件）在​​android系统的ImageView [英] How to get imageView inside onTouchEvent(MotionEvent event) in android

问题描述

我定义onTouchEvent（MotionEvent事件），以接收ImageView的触摸事件。我使用多个imageviews，我必须找到它的ImageView我收到触摸事件。
是否有可能进去onTouchEvent ImageView的？

 公共无效createImageViews（）
{
  INT I = 0;  imageArray [0] =（ImageView的）findViewById（R.id.image1）;
  imageArray [1] =（ImageView的）findViewById（R.id.image2）;
  imageArray [2] =（ImageView的）findViewById（R.id.image3）;
  imageArray [3] =（ImageView的）findViewById（R.id.image4）;
  imageArray [4] =（ImageView的）findViewById（R.id.image5）;
  imageArray [5] =（ImageView的）findViewById（R.id.image6）;  对于（i = 0; I＆LT;计数;我++）
  {
    imageArray [I] .setOnTouchListener（本）;
  }
}
 公共类触摸扩展活动实现OnTouchListener，AnimationListener {}
 

我已经尝试使用

 公共布尔onTouch（视图V，MotionEvent事件）{}，但没有收到触摸事件。
 

开始对ImageView的动画我没有观察到onTouch触摸事件（）和获取触摸事件的onTouchEvent（）之后。 imgArray [g_animCount] .startAnimation（movArray [g_animCount]）;

解决方案

 使用下面的示例code段::::    公共类MyImageView扩展活动实现OnTouchListener {
    @覆盖
    保护无效的onCreate（捆绑savedInstanceState）{
        // TODO自动生成方法存根
        super.onCreate（savedInstanceState）;
        的setContentView（R.layout.lay_name）;
        INT I = 0;
        imageArray [0] =（ImageView的）findViewById（R.id.image1）;
        imageArray [1] =（ImageView的）findViewById（R.id.image2）;
        imageArray [2] =（ImageView的）findViewById（R.id.image3）;
        imageArray [3] =（ImageView的）findViewById（R.id.image4）;
        imageArray [4] =（ImageView的）findViewById（R.id.image5）;
        imageArray [5] =（ImageView的）findViewById（R.id.image6）;        对于（i = 0; I＆LT;计数;我++）{
            imageArray [I] .setOnTouchListener（本）;
         }
    }    @覆盖
    公共布尔onTouch（视图V，MotionEvent事件）{
        // TODO自动生成方法存根
        开关（v.getId（））{
        案例R.id.image1：
        //你的东西
        打破;
        案例R.id.image2：
        //你的东西
        打破;
        案例R.id.image3：
        //你的东西
        打破;
        案例R.id.image4：
         //你的东西
        打破;
        案例R.id.image5：
         //你的东西
        打破;
        案例R.id.image6：
         //你的东西
        打破;
        }
    }
 

}

I defined onTouchEvent(MotionEvent event) to receive touch events for imageview. I am using multiple imageviews and i have to find for which imageview I have received touch event. Is it possible to get imageview inside onTouchEvent?

public void createImageViews()
{
  int i = 0;

  imageArray[0] = (ImageView)findViewById(R.id.image1);
  imageArray[1] = (ImageView)findViewById(R.id.image2);
  imageArray[2] = (ImageView)findViewById(R.id.image3);
  imageArray[3] = (ImageView)findViewById(R.id.image4);
  imageArray[4] = (ImageView)findViewById(R.id.image5);
  imageArray[5] = (ImageView)findViewById(R.id.image6);

  for (i = 0; i < count; i++)
  {
    imageArray[i].setOnTouchListener(this);
  } 
}
 public class Touch extends Activity implements OnTouchListener, AnimationListener { }

I have tried using

 public boolean onTouch(View v, MotionEvent event) { } but not receiving the touch events.

After starting the animation on imageview I did not observe touch events in onTouch() and getting touch events in onTouchEvent() . imgArray[g_animCount].startAnimation(movArray[g_animCount]);

解决方案

use the below sample code snippet::::

    public class MyImageView extends Activity implements OnTouchListener{
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.lay_name);        
        int i = 0;
        imageArray[0] = (ImageView)findViewById(R.id.image1);
        imageArray[1] = (ImageView)findViewById(R.id.image2);
        imageArray[2] = (ImageView)findViewById(R.id.image3);
        imageArray[3] = (ImageView)findViewById(R.id.image4);
        imageArray[4] = (ImageView)findViewById(R.id.image5);
        imageArray[5] = (ImageView)findViewById(R.id.image6);

        for (i = 0; i < count; i++)  {
            imageArray[i].setOnTouchListener(this);
         } 


    }

    @Override
    public boolean onTouch(View v, MotionEvent event) {
        // TODO Auto-generated method stub
        switch(v.getId()){
        case R.id.image1:
        //your stuff
        break;
        case R.id.image2:
        //your stuff        
        break;
        case R.id.image3:
        //your stuff
        break;
        case R.id.image4:
         //your stuff
        break;
        case R.id.image5:
         //your stuff
        break;
        case R.id.image6:
         //your stuff
        break;
        }
    }

}
