步骤1：添加Recyclerview视图布局。
步骤2：Recyclerview行布局recycler_item.xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.CardView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:card_view="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_margin="8dp"
card_view:cardCornerRadius="4dp">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:id="@+id/itemTextView"
style="@style/Base.TextAppearance.AppCompat.Body2"
android:layout_width="wrap_content"
android:layout_height="?attr/listPreferredItemHeight"
android:gravity="center_vertical"
android:layout_centerVertical="true"
android:padding="8dp" />
<ImageView
android:id="@+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:src="@mipmap/more"
android:layout_alignParentRight="true"
android:text="Button"
android:padding="10dp"
android:layout_marginRight="10dp"/>
</RelativeLayout>
</android.support.v7.widget.CardView>
第三步. RecyclerAdapter
public class RecyclerAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {
private List<String> mItemList;
public RecyclerAdapter(List<String> itemList) {
mItemList = itemList;
}
@Override
public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
Context context = parent.getContext();
View view = LayoutInflater.from(context).inflate(R.layout.recycler_item, parent, false);
return RecyclerItemViewHolder.newInstance(view);
}
@Override
public void onBindViewHolder(RecyclerView.ViewHolder viewHolder, int position) {
RecyclerItemViewHolder holder = (RecyclerItemViewHolder) viewHolder;
String itemText = mItemList.get(position);
holder.setItemText(itemText);
}
@Override
public int getItemCount() {
return mItemList == null ? 0 : mItemList.size();
}
}
步骤4 菜单布局navigation_drawer_menu_items.xml
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
>
<item
android:id="@+id/navigation_drawer_item1"
android:icon="@android:drawable/ic_dialog_map"
android:title="Item 1" />
<item
android:id="@+id/navigation_drawer_item2"
android:icon="@android:drawable/ic_dialog_info"
android:title="Item 2" />
<item
android:id="@+id/navigation_drawer_item3"
android:icon="@android:drawable/ic_menu_share"
android:title="Item 3"/>
</menu>
步骤5：添加RecyclerItemClickListener.java类
import android.content.Context;
import android.support.v7.widget.RecyclerView;
import android.view.GestureDetector;
import android.view.MotionEvent;
import android.view.View;
public class RecyclerItemClickListener implements RecyclerView.OnItemTouchListener {
private OnItemClickListener mListener;
public interface OnItemClickListener {
void onItemClick(View view, int position);
}
GestureDetector mGestureDetector;
public RecyclerItemClickListener(Context context, OnItemClickListener listener) {
mListener = listener;
mGestureDetector = new GestureDetector(context, new GestureDetector.SimpleOnGestureListener() {
@Override public boolean onSingleTapUp(MotionEvent e) {
return true;
}
});
}
@Override public boolean onInterceptTouchEvent(RecyclerView view, MotionEvent e) {
View childView = view.findChildViewUnder(e.getX(), e.getY());
if (childView != null && mListener != null && mGestureDetector.onTouchEvent(e)) {
mListener.onItemClick(childView, view.getChildAdapterPosition(childView));
}
return false;
}
@Override public void onTouchEvent(RecyclerView view, MotionEvent motionEvent) { }
@Override public void onRequestDisallowInterceptTouchEvent(boolean disallowIntercept) {
}
}
步骤6：在Recyclerview上添加ItemTouchListener。
private void initRecyclerView() {
RecyclerView recyclerView = (RecyclerView) findViewById(R.id.recyclerView);
recyclerView.setLayoutManager(new LinearLayoutManager(this));
RecyclerAdapter recyclerAdapter = new RecyclerAdapter(createItemList());
recyclerView.setAdapter(recyclerAdapter);
recyclerView.addOnItemTouchListener(new RecyclerItemClickListener(this, new RecyclerItemClickListener.OnItemClickListener() {
@Override
public void onItemClick(View view, final int position) {
ImageView moreImage = (ImageView) view.findViewById(R.id.button);
moreImage.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
openOptionMenu(v,position);
}
});
}
})
);
}
步骤4 创建弹出菜单。
public void openOptionMenu(View v,final int position){
PopupMenu popup = new PopupMenu(v.getContext(), v);
popup.getMenuInflater().inflate(R.menu.navigation_drawer_menu_items, popup.getMenu());
popup.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
@Override
public boolean onMenuItemClick(MenuItem item) {
Toast.makeText(getBaseContext(), "You selected the action : " + item.getTitle()+" position "+position, Toast.LENGTH_SHORT).show();
return true;
}
});
popup.show();
}
android:textStyle="bold"参数，否则看起来会太细。 - acmpo6ouTextView包装在任何其他ViewGroup中，例如RelativeLayout，并为该RelativeLayout设置padding属性。 - Feroz Khan
