Question

我遇到了android listview的问题。我的 ListView 中有多个按钮，我想为每个按钮设置setclicklistener并检索它们在ListView中的位置。

ListItem.xml

<Button xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/btnList"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:gravity="center_vertical"
    android:paddingLeft="16dp"
    android:paddingRight="16dp"
    android:textColor="#fff" />

MainActivity.java

mDrawerList.setAdapter(new ArrayAdapter<String>(
                getApplicationContext(), R.layout.drawer_list_item,
                mPlanetTitles));

按钮OnClickListener

btnList.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) 
            {
               new DrawerItemClickListener();   
            }
        });

班级DrawerItemClickListener

private static class DrawerItemClickListener implements
            ListView.OnItemClickListener  {

        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position,
                long id) {
        MainActivity main= new MainActivity();
        main.selectItem(position);
        }
    }

Answer 1

使用此选项，OnItemClick中的位置是按钮在列表中的位置

listview.setOnItemClickListener(new OnItemClickListener() {

    @Override
    public void onItemClick(AdapterView<?> adapterView, View view, int position, long id) {
    }

您需要在listview适配器的getview中处理按钮的on click侦听器，您可以使用view.findViewById（R.id.yourButtonID）找到该按钮。这就是你如何做到的：

Button yourButton= (Button) rowView.findViewById(R.id.yourButtonID); // be carefull to use the view of the listItem and not the activity in case the adapter is inside the Activity.
yourButton.setTag(position);// Any data associated with the button has to be added with setTag()
yourButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View arg0) {
                      Log.w("DEBUG_TAG", "Button Clicked at position : " + position);
                      //here you must use getTag() in order to extract the data set in the setTag()
            }
        });

Listview中每个Button的setOnclicklistener
