如何在列表视图中添加单击侦听器，如果ListView已经在xml中按下了？我想点击按钮打开新活动。
这是我的代码。 WashDetail.xml
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:gravity="center"
android:orientation="horizontal">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#000"
android:text="Malaber Hill" />
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="10dp"
android:layout_marginLeft="16dp"
android:layout_marginEnd="20dp"
android:text="Get Details"
android:id="@+id/gardetails"
android:textColor="#FFFFFF"
android:textSize="20dp"
android:textStyle="normal"
/>
</LinearLayout>
activity_wash_detail
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ListView
android:layout_width="fill_parent"
android:id="@+id/ls"
android:layout_below="@+id/headerlay"
android:focusable="true"
android:clickable="true"
android:duplicateParentState="true"
android:focusableInTouchMode="true"
android:layout_height="fill_parent">
</ListView>
</LinearLayout>
WashDetailActivity.java
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_wash_detail);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
listView = (ListView) findViewById(ls);
GetDetails=(Button)findViewById(R.id.gardetails);
Models = new ArrayList<>();
Models.add(new WashDetailing(R.drawable.spl, "PP AUTOMATIVES", R.drawable.mahindra, "Authorized"));
adapter = new WashDetailingAdapter(Models, getApplicationContext());
listView.setAdapter(adapter);
listView.setClickable(false);
gardetails.setOnClickListener(new View.OnClickListener() {
public void onClick(View v)
{
Intent intent= new Intent(getApplicationContext(),GarageDetailActivity.class);
startActivity(intent);
}
});
}

我们这样做......但坦率地说，你的问题对我来说并不清楚。
listview.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int
position, long id) {
}
});

表示你想在listview中点击按钮，对吗？

在适配器类的getView方法中设置此单击侦听器
public View getView(final int position, View convertView, ViewGroup parent) {
ViewHolder holder = null;
// Inflater for custom layout
LayoutInflater inflater = (LayoutInflater)dContext
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
if (convertView == null) {
convertView = inflater.inflate(R.layout.customer_list_layout, parent, false);
holder.gardetails = convertView.findViewById(R.id.gardetails);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
holder.gardetails.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent intent= new Intent(getApplicationContext(),GarageDetailActivity.class);
dContext.startActivity(intent)
}
});
return convertView;
}
这是您的ViewHolder类
私有类ViewHolder {
Button gardetails;
}

使用自定义适配器这样
public class Custom_Adapter_Products extends BaseAdapter {
Context context;
Cursor mCursor;
static int[] intArr;
DatabaseAdapter db;
public ImageLoader imageLoader;
public Custom_Adapter_Products(Context context, Cursor mCursor){
this.context = context;
this.mCursor = mCursor;
this.intArr = new int[this.mCursor.getCount()];
imageLoader=new ImageLoader(context);
}
@Override
public int getCount() {
return mCursor.getCount();
}
@Override
public Object getItem(int position) {
return null;
}
@Override
public long getItemId(int position) {
return position;
}
@Override
public View getView(final int position, View convertView, ViewGroup parent) {
try{
ViewHolder holder;
this.mCursor.moveToPosition(position);
LayoutInflater vi = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
if (convertView == null)
{
convertView = vi.inflate(R.layout.lv_row_for_products, null);
holder = createViewHolder(convertView);
convertView.setTag(holder);
holder.btnMinus.setTag(holder);
holder.btnAdd.setTag(holder);
}
else
{
holder = (ViewHolder) convertView.getTag();
}
holder.btnMinus.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
try{
ViewHolder holder = (ViewHolder) v.getTag();
// Do whatever you want
}catch (Exception e) {
// TODO: handle exception
e.printStackTrace();
}
}
});
holder.btnAdd.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
try{
ViewHolder holder = (ViewHolder) v.getTag();
}catch (Exception e) {
// TODO: handle exception
e.printStackTrace();
}}
});
String strProductName = this.mCursor.getString(this.mCursor.getColumnIndex(DatabaseAdapter.PRODUCT_NAME));
String strPrice = this.mCursor.getString(this.mCursor.getColumnIndex(DatabaseAdapter.PRICE));
String strMOQ = this.mCursor.getString(this.mCursor.getColumnIndex(DatabaseAdapter.MOQ));
String strProductId = this.mCursor.getString(this.mCursor.getColumnIndex(DatabaseAdapter.PRODUCT_ID));
String strMrp = this.mCursor.getString(this.mCursor.getColumnIndex(DatabaseAdapter.MRP));
holder.tvProductName.setText(strProductName);
holder.tvPrice.setText(context.getString(R.string.Rupee)+" "+strPrice);
}catch (Exception e){
// TODO: handle exception
e.printStackTrace();
}
return convertView;
}
private static class ViewHolder
{
public TextView tvProductName;
public TextView tvPrice;
public TextView tvMRP;
public TextView tvMOQ;
public TextView tvPercent;
public TextView tvQuantity;
public ImageView imgProduct;
public ProgressBar pBar;
public Button btnMinus;
public Button btnAdd;
}
private ViewHolder createViewHolder(View v) {
ViewHolder holder = new ViewHolder();
try{
holder.tvProductName = (TextView) v.findViewById(R.id.tvProductName);
holder.tvPrice = (TextView) v.findViewById(R.id.tvPrice);
holder.tvMRP = (TextView) v.findViewById(R.id.tvMRP);
holder.tvMOQ = (TextView) v.findViewById(R.id.tvMOQ);
holder.tvQuantity = (TextView) v.findViewById(R.id.tvQuantity);
holder.imgProduct = (ImageView) v.findViewById(R.id.imgProduct);
holder.pBar = (ProgressBar) v.findViewById(R.id.img_pb);
holder.btnMinus = (Button) v.findViewById(R.id.btnMinus);
holder.btnAdd = (Button) v.findViewById(R.id.btnAdd);
holder.tvPercent = (TextView) v.findViewById(R.id.tvPercent);
}catch (Exception e) {
// TODO: handle exception
e.printStackTrace();
}
return holder;
}
}

在Listview Adapter类
上使用此代码@Override
public View getView(final int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = context.getLayoutInflater();
View listViewItem = inflater.inflate(R.layout.item_rating_rows, null, true);
Button btn = (Button) listViewItem.findViewById(R.id.btn);
btn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Log.d("__onclick", "" + view.getId());
}
});
