我想在 android studio 中制作一個儀表板。我使用兩個 xml 來制作儀表板 main_activity 和 list_item 活動。在編碼會話中，我使用了模型類適配器和主類。public class MainActivity extends AppCompatActivity {ArrayList<DashModel> dashModelArrayList;DashAdapter dashAdapter;private RecyclerView recyclerView;@Overrideprotected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); recyclerView = findViewById(R.id.rv1); dashModelArrayList = new ArrayList<>(); String heads[] = {"Jobs", "My Profile", "Messages", "Applied Jobs", "Resume", "Settings"}; String subs[] = {"12 new jobs found", "75% complete", "2 new messages", "3 applies jobs", "Edit resume", "Set preferences"}; int images[] = {R.drawable.find_jobs, R.drawable.profile, R.drawable.messages, R.drawable.applied_jobs, R.drawable.resume, R.drawable.settings}; for (int count = 0; count < heads.length; count++) { DashModel dashModel = new DashModel(); dashModel.setHead(heads[count]); dashModel.setSub(subs[count]); dashModel.setImage(images[count]); dashModelArrayList.add(dashModel); //this should be retrieved in our adapter } recyclerView.setLayoutManager(new GridLayoutManager(getApplicationContext(), 2)); dashAdapter = new DashAdapter(dashModelArrayList); recyclerView.setHasFixedSize(true); recyclerView.setAdapter(dashAdapter);}}如何在此處添加 onItemclickListener？我希望并希望在圖標中添加 OnItemclickListener，但我不能也不知道如何添加。

要為 RecyclerView 創建一個，onClickListener你必須創建一個類來實現RecyclerView.OnItemTouchListener
import android.support.v7.widget.*;
import android.view.*;
import android.content.*;
public class RecyclerViewTouchListener implements RecyclerView.OnItemTouchListener {
private GestureDetector gestureDetector;
private ClickListener clickListener;
public RecyclerViewTouchListener(Context context, final RecyclerView recyclerView, final ClickListener clickListener) {
this.clickListener = clickListener;
gestureDetector = new GestureDetector(context, new GestureDetector.SimpleOnGestureListener() {
@Override
public boolean onSingleTapUp(MotionEvent e) {
return true;
}
@Override
public void onLongPress(MotionEvent e) {
View child = recyclerView.findChildViewUnder(e.getX(), e.getY());
if (child != null && clickListener != null) {
clickListener.onLongClick(child, recyclerView.getChildPosition(child));
}
}
});
}
@Override
public boolean onInterceptTouchEvent(RecyclerView rv, MotionEvent e) {
View child = rv.findChildViewUnder(e.getX(), e.getY());
if (child != null && clickListener != null && gestureDetector.onTouchEvent(e)) {
clickListener.onClick(child, rv.getChildPosition(child));
}
return false;
}
@Override
public void onTouchEvent(RecyclerView rv, MotionEvent e) {
}
@Override
public void onRequestDisallowInterceptTouchEvent(boolean disallowIntercept) {
}
public interface ClickListener{
public void onClick(View view,int position);
public void onLongClick(View view,int position);
}
}
之后，您可以將其附加到您的設備上RecyclerView以收聽點擊。
recyclerView.addOnItemTouchListener(new RecyclerViewTouchListener(getActivity(), recyclerView, new RecyclerViewTouchListener.ClickListener(){
@Override
public void onClick(View view, int position)
{
// TODO: Implement this method
}
@Override
public void onLongClick(View view, int position)
{
// TODO: Implement this method
}
}));
