【问题描述】:
我动态创建了以下RecyclerView。我想在单击时突出显示单击的项目。点击后跳转到下一个Activity。我在下面给出了背景 XML:
hRecyclerView.setBackgroundResource(R.drawable.mylistview_background);
这不是设置方法吗?我应该在这里做什么?
hRecyclerView = (RecyclerView) findViewById(R.id.my_history_view);
// use a linear layout manager
hLayoutManager = new LinearLayoutManager(this);
hRecyclerView.setLayoutManager(hLayoutManager);
hRecyclerView.setVerticalScrollBarEnabled(false);
hRecyclerView.addItemDecoration(new DividerItemDecoration(this, DividerItemDecoration.VERTICAL_LIST));
hRecyclerView.setBackgroundResource(R.drawable.mylistview_background);
hAdapter = new HistoryAdapter(history, this);
hRecyclerView.setAdapter(hAdapter);
hRecyclerView.addOnItemTouchListener(
new RecyclerItemClickListener(context, new RecyclerItemClickListener.OnItemClickListener() {
@Override
public void onItemClick(View view, int position) {
// do whatever
if(position>0) {
History his = history.get(position - 1);
Intent intent = new Intent(getApplicationContext(), TrackActivity.class);
intent.putExtra("from", his.src_station);
intent.putExtra("to", his.dest_station);
intent.putExtra("train_no", his.train_no);
intent.putExtra("train_name", his.train_name);
startActivity(intent);
overridePendingTransition(R.anim.right_in, R.anim.left_out);
}
}
})
);
hRecyclerView.setItemAnimator(new DefaultItemAnimator());
mylistview_background.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true">
<shape>
<gradient android:endColor="#22000000" android:startColor="#a7a2288f" android:angle="270" />
</shape>
</item>
<item android:state_focused="true">
<shape>
<gradient android:endColor="#2200ff00" android:startColor="#a2008f00" android:angle="270" />
</shape>
</item>
</selector>
非常感谢任何帮助!

您是否有理由不在 ViewHolder 类中使用 onClickListenner 来处理点击事件?昨天我花了很多时间为这种情况想出最好的解决方案,对我来说这样更容易。如果有什么我不知道的,请告诉我。
