【中文标题】Listview自定义适配器无法选择项目【英文标题】：Listview custom adapter cant select an item 【发布时间】：2019-03-03 08:43:43 【问题描述】：我尝试了我在 *** 中找到的所有解决方案，但似乎它们都不起作用。
这是我的主要活动：
public class MerchantLocatorActivity extends AppCompatActivity implements OnMapReadyCallback
public void init()
merchantLocatorResponseObject = new MerchantLocatorResponse();
merchantLocatorResponseObject.setTitle("Spherical");
merchantLocatorResponseObject.setAddress("8007 Pioneer St, Kapitolyo, Mandaluyong, 1550 Metro Manila");
merchantLocatorResponseObject.setLatitude( 14.573249);
merchantLocatorResponseObject.setLongitude(121.057022);
merchantLocatorObjectArray.add(merchantLocatorResponseObject);
merchantLocatorResponseObject = new MerchantLocatorResponse();
merchantLocatorResponseObject.setTitle("Globe");
merchantLocatorResponseObject.setAddress("SCT, 584 Shaw Blvd, Mandaluyong, 1552 Metro Manila");
merchantLocatorResponseObject.setLatitude(14.585095);
merchantLocatorResponseObject.setLongitude(121.048893);
merchantLocatorObjectArray.add(merchantLocatorResponseObject);
merchantLocatorResponseObject = new MerchantLocatorResponse();
merchantLocatorResponseObject.setTitle("Sparndium");
merchantLocatorResponseObject.setAddress("Xavier, San Juan, 1502 Metro Manila");
merchantLocatorResponseObject.setLatitude(14.601918);
merchantLocatorResponseObject.setLongitude(121.042169);
merchantLocatorObjectArray.add(merchantLocatorResponseObject);
addMarker();
@OnClick(R.id.fab)
public void showAccToDialog()
AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(this);
View alertView = LayoutInflater.from(this).inflate(R.layout.dialog_biller, null);
alertDialogBuilder.setView(alertView);
final AlertDialog dialog = alertDialogBuilder.create();
dialog.show();
final ListView listViewBillers = (ListView) dialog.findViewById(R.id.biller_institutions_listview);
if (listViewBillers != null)
MerchantLocatorAdapter adapter = new MerchantLocatorAdapter(
this, R.layout.merchant_locator_adapter, merchantLocatorObjectArray);
listViewBillers.setAdapter(adapter);
listViewBillers.setOnItemClickListener(new AdapterView.OnItemClickListener()
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id)
geoLocate(merchantLocatorObjectArray,position);
DebugUtils.log("TESTTESTACTIVITYZXC");
DebugUtils.showToast(MerchantLocatorActivity.this,"HAHAHAH");
dialog.dismiss();
);
final EditText mSearchedittext = (EditText) dialog.findViewById(R.id.search_edittext);
mSearchedittext.addTextChangedListener(new TextWatcher()
@Override
public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2)
@Override
public void onTextChanged(CharSequence charSequence, int i, int i1, int i2)
final ArrayList<MerchantLocatorResponse> searchResultObject = new ArrayList<>();
searchResultObject.clear();
for (int hay = 0; hay <= merchantLocatorObjectArray.size() - 1; hay++)
if ( merchantLocatorObjectArray.get(hay).getTitle().toLowerCase().contains(charSequence))
searchResultObject.add( merchantLocatorObjectArray.get(hay));
MerchantLocatorAdapter adapter = new MerchantLocatorAdapter(
MerchantLocatorActivity.this, R.layout.merchant_locator_adapter, searchResultObject);
listViewBillers.setAdapter(adapter);
listViewBillers.setOnItemClickListener(new AdapterView.OnItemClickListener()
@Override
public void onItemClick(AdapterView<?> adapter, View view, int position, long arg)
geoLocate(searchResultObject,position);
dialog.dismiss();
);
@Override
public void afterTextChanged(Editable editable)
);
我删除了代码的某些部分，因为我认为没有必要包含，但如果有某些部分我需要澄清，请告诉我。
目前在我的主要活动中，我正在调用一个包含列表视图的对话框，并且在我的列表视图中我有项目。
我的问题是我无法选择我的任何项目，即使我有我的 setOnitemclick 监听器。
这是我的适配器：
public class MerchantLocatorAdapter extends BaseAdapter
private int resourceLayout;
private Context mContext;
ArrayList<MerchantLocatorResponse> merchantLocatorarray = new ArrayList<>();
public MerchantLocatorAdapter(Context context, int resource, ArrayList<MerchantLocatorResponse> merchantLocatorResponsesobjectArray)
this.resourceLayout = resource;
this.mContext = context;
this.merchantLocatorarray = merchantLocatorResponsesobjectArray;
@Override
public int getCount()
return merchantLocatorarray.size();
@Override
public Object getItem(int position)
return null;
@Override
public long getItemId(int position)
return 0;
@Override
public View getView(final int position, View convertView, ViewGroup parent)
if (convertView == null)
LayoutInflater inflater = (LayoutInflater) mContext
.getSystemService(mContext.LAYOUT_INFLATER_SERVICE);
convertView = inflater.inflate(resourceLayout, parent, false);
TextView tt1 = (TextView) convertView.findViewById(R.id.field_name_textview);
TextView tt2 = (TextView) convertView.findViewById(R.id.field_value_textview);
ImageButton direction = (ImageButton) convertView.findViewById(R.id.direction);
tt1.setText(merchantLocatorarray.get(position).getTitle());
tt2.setText(merchantLocatorarray.get(position).getAddress());
return convertView;
这是我的适配器布局：

我尝试了我在 *** 中找到的所有解决方案，但我仍然无法单击我的项目。所以请不要将此标记为重复。
如果代码中有任何需要澄清的部分，请发表评论，我会尽快回复。谢谢。
【问题讨论】：
查看答案 您的项目布局中有 ImageButton 通常会阻止单击事件。尝试将android:descendantFocusability="blocksDescendants 添加到项目视图的根布局中。希望有帮助！
@I_A_Mok 会让我的 imageButton 无法点击吗？抱歉，我不知道descendantFocusability。会查查的。
找到了问题的根源，当我尝试点击卡片视图之外时，我可以点击该项目。但是当我尝试点击卡片视图本身时，它不会工作。
【参考方案1】：
尝试在您的自定义适配器中使用Observable：
// Define
private final PublishSubject<MerchantLocatorResponse> onItemClick = PublishSubject.create();
// Create the observable method
public Observable<ConversationMessage> getObservable()
return onItemClick;
// Set the onClickListener into getView()
convertView.setOnClickListener(new View.OnClickListener()
@Override
public void onClick(View v)
onItemClick.onNext(merchantLocatorarray.get(position));
);
然后，在你的主要活动中听它并处理点击：
@OnClick(R.id.fab)
public void showAccToDialog()
// bla bla bla
listViewBillers.setAdapter(adapter);
listViewBillers.getObservable().subscribe(geoLocate);
// bla bla bla
Consumer<MerchantLocatorResponse> geoLocate = new Consumer<MerchantLocatorResponse>()
@Override
public void accept(MerchantLocatorResponse mlr)
// Code after click event
;
在你的 gradle 中添加这些库：
implementation "io.reactivex.rxjava2:rxjava:2.1.5"
implementation "io.reactivex.rxjava2:rxandroid:2.0.1"
【讨论】：
setOnclickListener 本身不工作。我无法单击我的视图。 :( 尝试将父布局上的android:clicable="true" 和android:focusable="true" 设置为resourceLayout【参考方案2】：
在您的代码中添加convertView.setOnclickListener()。在您的适配器中尝试以下代码
@Override
public View getView(final int position, View convertView, ViewGroup parent)
if (convertView == null)
LayoutInflater inflater = (LayoutInflater) mContext
.getSystemService(mContext.LAYOUT_INFLATER_SERVICE);
convertView = inflater.inflate(resourceLayout, parent, false);
TextView tt1 = (TextView) convertView.findViewById(R.id.field_name_textview);
TextView tt2 = (TextView) convertView.findViewById(R.id.field_value_textview);
ImageButton direction = (ImageButton) convertView.findViewById(R.id.direction);
tt1.setText(merchantLocatorarray.get(position).getTitle());
tt2.setText(merchantLocatorarray.get(position).getAddress());
convertView.setOnClickListener(new View.OnClickListener()
@Override
public void onClick(View view)
Toast.makeText(context, String.valueOf(position), Toast.LENGTH_SHORT).show();
);
return convertView;
