Question

我希望能够点击并滚动图像视图，但每当我触摸图像视图并执行＆＃34;动作移动时，就会发生这种情况。它不滚动但执行＆＃34;点击事件＆＃34;代替！我希望能够做到这两个意思，当我触摸和移动它应该滚动，但当我只是触摸然后它应该执行点击！提前致谢

这就是我所做的

    ImageView ivUser = (ImageView) findViewById(R.id.ivUser);
    ivUser.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            Intent intent = new Intent(StoryDetails.this, ProfileView.class);
            intent.putExtra("id", usersid);
            Log.d("ivUser attempt", usersid);
            startActivity(intent);
        }
    });

我刚刚实现了＆＃34; onTouch监听器＆＃34;像下面的代码，但我不知道下一步该做什么！

    ivPost.setOnTouchListener(new OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            switch (event.getAction()) {
            case MotionEvent.ACTION_DOWN: {
                Log.d("ACTION_DOWN", "ACTION_DOWN");
                break;
            }
            case MotionEvent.ACTION_MOVE:{
                Log.d("ACTION_MOVE", "ACTION_MOVE");
                break;
            }
            case MotionEvent.ACTION_CANCEL:{
                Log.d("LENGTH_LONG!", "LENGTH_LONG");
                break;
            }
            }
            return true;
        }
   });

image.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View arg0) {
            // TODO Auto-generated method stub
            Toast.makeText(getBaseContext(), "image clicked", Toast.LENGTH_LONG).show();
        }
    });

    image.setOnTouchListener(new OnTouchListener() {

        @Override
        public boolean onTouch(View arg0, MotionEvent arg1) {
            // TODO Auto-generated method stub              
            switch (arg1.getAction()) {
            case MotionEvent.ACTION_UP: 
                // where user releases finger 
                if(!moved){
                    Toast.makeText(getBaseContext(), String.valueOf(moved), Toast.LENGTH_SHORT).show();
                    image.performClick(); // you use this if you badly need the onclick listener
                    // but you can replace and put your onclick listener codes directly here
                }
                break;

            case MotionEvent.ACTION_MOVE:
                moved = true;
                Toast.makeText(getBaseContext(), "image is moving", Toast.LENGTH_SHORT).show();
                Toast.makeText(getBaseContext(), String.valueOf(moved), Toast.LENGTH_SHORT).show(); // scroll your stuff here, meaning put the scrolling codes here
                break;

            case MotionEvent.ACTION_DOWN:                   
                //this is where touch is trigered, you can call the performclick function here                   
                // this will always b called first but we can do some boolean magic here..
                moved = false;
                break;
            }
            return true;
        }
    });

你的布尔值应该是一个全局变量private boolean moved; // this is the boolean

imageView可点击和可滚动
