MyRecyclerViewAdapter.java
public class MyRecyclerViewAdapter extends RecyclerView
.Adapter<MyRecyclerViewAdapter
.DataObjectHolder> {
private static String LOG_TAG = "MyRecyclerViewAdapter";
private ArrayList<DataObject> mDataset;
private static MyClickListener myClickListener;
public static class DataObjectHolder extends RecyclerView.ViewHolder
implements View
.OnClickListener {
TextView label;
TextView dateTime;
public DataObjectHolder(View itemView) {
super(itemView);
label = (TextView) itemView.findViewById(R.id.textView);
dateTime = (TextView) itemView.findViewById(R.id.textView2);
Log.i(LOG_TAG, "Adding Listener");
itemView.setOnClickListener(this);
label.setOnClickListener(this);
dateTime.setOnClickListener(this);
}
@Override
public void onClick(View v) {
if(v.getId() == label.getId()){
label.setBackgroundColor(Color.parseColor("#FFFF00"));
}else if(v.getId() == dateTime.getId()){
dateTime.setBackgroundColor(Color.parseColor("#0000FF"));
}else{
Toast.makeText(v.getContext(), "ROW PRESSED = " + String.valueOf(getAdapterPosition()), Toast.LENGTH_SHORT).show();
}
int position = getAdapterPosition();
Log.i(LOG_TAG, String.valueOf(position));
myClickListener.onItemClick(position, v);
}
}
public void setOnItemClickListener(MyClickListener myClickListener) {
this.myClickListener = myClickListener;
}
public MyRecyclerViewAdapter(ArrayList<DataObject> myDataset) {
mDataset = myDataset;
}
@Override
public DataObjectHolder onCreateViewHolder(ViewGroup parent,
int viewType) {
View view = LayoutInflater.from(parent.getContext())
.inflate(R.layout.recyclerview_item, parent, false);
DataObjectHolder dataObjectHolder = new DataObjectHolder(view);
return dataObjectHolder;
}
@Override
public void onBindViewHolder(DataObjectHolder holder, int position) {
holder.label.setText(mDataset.get(position).getmText1());
holder.dateTime.setText(mDataset.get(position).getmText2());
}
public void addItem(DataObject dataObj, int index) {
mDataset.add(dataObj);
notifyItemInserted(index);
}
public void deleteItem(int index) {
mDataset.remove(index);
notifyItemRemoved(index);
}
@Override
public int getItemCount() {
return mDataset.size();
}
public interface MyClickListener {
public void onItemClick(int position, View v);
}
}
DataObject.java
public class DataObject {
private String mText1;
private String mText2;
DataObject (String text1, String text2){
mText1 = text1;
mText2 = text2;
}
public String getmText1() {
return mText1;
}
public void setmText1(String mText1) {
this.mText1 = mText1;
}
public String getmText2() {
return mText2;
}
public void setmText2(String mText2) {
this.mText2 = mText2;
}
}
MainActivity.java
public class MainActivity extends AppCompatActivity {
private RecyclerView mRecyclerView;
private RecyclerView.Adapter mAdapter;
private RecyclerView.LayoutManager mLayoutManager;
private static String LOG_TAG = "RecyclerViewActivity";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mRecyclerView = (RecyclerView) findViewById(R.id.my_recycler_view);
mRecyclerView.setHasFixedSize(true);
mLayoutManager = new LinearLayoutManager(this);
mRecyclerView.setLayoutManager(mLayoutManager);
mAdapter = new MyRecyclerViewAdapter(getDataSet());
mRecyclerView.setAdapter(mAdapter);
RecyclerView.ItemDecoration itemDecoration =
new DividerItemDecoration(this, LinearLayoutManager.VERTICAL);
mRecyclerView.addItemDecoration(itemDecoration);
}
@Override
protected void onResume() {
super.onResume();
((MyRecyclerViewAdapter) mAdapter).setOnItemClickListener(new
MyRecyclerViewAdapter.MyClickListener() {
@Override
public void onItemClick(int position, View v) {
Log.i(LOG_TAG, " Clicked on Item " + position);
}
});
}
private ArrayList<DataObject> getDataSet() {
ArrayList results = new ArrayList<DataObject>();
for (int index = 0; index < 20; index++) {
DataObject obj = new DataObject("F-" + index,
"S-" + index);
results.add(index, obj);
}
return results;
}
}
Also, können Sie bitte führen Sie mich, wie Sie Element für nur eine Zeile auswählen?
Vielen Dank im Voraus.
