android - 使用 ButterKnife 了解点击 View

Question

我有这段代码:

@OnClick( {R.id.iv_first,R.id.iv_second} )
public void launchCards() {
    Log.i(TAG,"clicked");
}

有没有办法知道在 launchCards() 方法中点击了两个 ImageView 中的哪一个？

Answer 1

你可以这样做:

@OnClick({R.id.iv_first,R.id.iv_second}) 
public void launchCards(View view) {

        // Check which ImageView was clicked
        switch (view.getId()) {
          case R.id.iv_first:
              // 1 clicked
            break;
          case R.id.iv_second:
              // 2 clicked
            break;
        }
      }
