您好我有ImageView的在我使用的类似按钮的onClick事件给我的Andr​​oid应用程序，但您可能已经猜到点击时，它是不会放弃的ImageView一个可点击的效果，我怎么能做到这一点？

Hi I have imageview in my android app that i am using like button with onClick event given , but as you might guess it is not giving imageview a clickable effect when clicked , how can i achieve that ??

推荐答案

您可以设计不同的图像，点击/不点击状态和设置他们在onTouchListener如下：

You can design different images for clicked/not clicked states and set them in the onTouchListener as follows

final ImageView v = (ImageView) findViewById(R.id.button0);
        v.setOnTouchListener(new OnTouchListener() {
            @Override
            public boolean onTouch(View arg0, MotionEvent arg1) {
                switch (arg1.getAction()) {
                case MotionEvent.ACTION_DOWN: {
                    v.setImageBitmap(res.getDrawable(R.drawable.img_down));
                    break;
                }
                case MotionEvent.ACTION_CANCEL:{
                    v.setImageBitmap(res.getDrawable(R.drawable.img_up));
                    break;
                }
                }
                return true;
            }
        });

更好的选择是您定义的选择如下：

The better choice is that you define a selector as follows

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_selected="true"   
        android:drawable="@drawable/img_down" />
    <item android:state_selected="false"   
        android:drawable="@drawable/img_up" />
</selector>

和事件选择图像：

v.setOnTouchListener(new OnTouchListener() {
            @Override
            public boolean onTouch(View arg0, MotionEvent arg1) {
                v.setSelected(arg1.getAction()==MotionEvent.ACTION_DOWN);
                return true;
            }
        });
