Question

在这个ListView不可点击的情况下，我想对项目点击执行操作，但我不知道为什么这不可点击，我也检查过调试控制器没有在itemclicklistener中消失。

设计文件：

  <?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
 android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >

<CheckBox
    android:id="@+id/cbSolved"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentLeft="true"
    android:layout_alignParentTop="true"
    android:layout_marginLeft="15dp"
    android:layout_marginTop="20dp"
    android:text="Show Solved" />

 <CheckBox
    android:id="@+id/cbMyCases"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignBaseline="@+id/cbSolved"
    android:layout_alignBottom="@+id/cbSolved"
    android:layout_alignParentRight="true"
    android:layout_marginRight="46dp"
    android:text="My Cases" />

<EditText
    android:id="@+id/etCaseSeacrh"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_below="@+id/cbSolved"
    android:layout_marginLeft="28dp"
    android:ems="10"
    android:hint="Search" >
</EditText>

<ListView
    android:id="@+id/liCases"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_above="@+id/btnNewCase"
    android:layout_alignParentLeft="true"
    android:layout_below="@+id/etCaseSeacrh"
    android:layout_marginTop="23dp"
    android:clickable="true" >
</ListView>

<Button
    android:id="@+id/btnNewCase"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:layout_alignParentLeft="true"
    android:layout_alignParentRight="true"
    android:text="New Case" />

</RelativeLayout>

这是我的java类，我正在访问列表但不可点击

public class ShowCases extends Activity{
  ListView listshowcase;
EditText search;
  ListViewAdapter adapter;

   @Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
       super.onCreate(savedInstanceState);
    setContentView(R.layout.screen4);

    listshowcase = (ListView) findViewById(R.id.liCases);
    adapter = new ListViewAdapter(this);
      listshowcase.setAdapter(adapter);
    listshowcase.setClickable(true);
    listshowcase.setOnItemClickListener(new AdapterView.OnItemClickListener() {

        @Override
        public void onItemClick(AdapterView<?> arg0, View view, int arg2,
                long arg3) {
            // TODO Auto-generated method stub
            String name = ((TextView) view.findViewById(R.id.name)).getText().toString();
            String cost = ((TextView) view.findViewById(R.id.email)).getText().toString();
            String description = ((TextView) view.findViewById(R.id.mobile)).getText().toString();
            String id = ((TextView) view.findViewById(R.id.id)).getText().toString();
            // Starting new intent
            Intent in = new Intent(getApplicationContext(), CompanyDetail.class);
            in.putExtra("name", name);
            in.putExtra("email", cost);
            in.putExtra("ff", description);
            in.putExtra("fff", id);
            startActivity(in);
        }
     });


    search=(EditText)findViewById(R.id.etCaseSeacrh);

    search.addTextChangedListener(new TextWatcher() {

        @Override
        public void onTextChanged(CharSequence s, int start, int before, int count) {
            // Call back the Adapter with current character to Filter

        }

        @Override
        public void beforeTextChanged(CharSequence s, int start, int count,int after) {
        }

                @Override
        public void afterTextChanged(Editable arg0) {
            // TODO Auto-generated method stub

         }
    });
  }

这是自定义Listadapter类的getview

@Override
    public View getView(final int paramInt, View paramView,
         final ViewGroup paramViewGroup) {
      // TODO Auto-generated method stub
      LayoutInflater inflator = activity.getLayoutInflater();
      if (paramView == null) {
         view = new ViewHolder();
         paramView = inflator.inflate(R.layout.list_item, null);

        view.name = (TextView) paramView.findViewById(R.id.name);
         view.email = (TextView) paramView.findViewById(R.id.email);
         view.mobile = (TextView) paramView.findViewById(R.id.mobile);
         view.id = (TextView) paramView.findViewById(R.id.id);
        paramView.setTag(view);

      } else {
         view = (ViewHolder) paramView.getTag();
      }

     view.name.setText(TAG_NAME.get(paramInt));
     view.email.setText(TAG_EMAIL.get(paramInt));
     view.mobile.setText(TAG_PHONE_MOBILE.get(paramInt));
     view.id.setText(TAG_ID.get(paramInt));
     /*view.name.setFocusableInTouchMode(false);
     view.name.setFocusable(false);*/
     /*view.setOnClickListener(myClickListener);*/
     view.name.setFocusable(false);
     view.email.setFocusable(false);
     view.mobile.setFocusable(false);
     view.id.setFocusable(false);

    return paramView;
 }

Answer 1

好的，你有一个按钮。在你的list_item xml中，将android:descendantFocusability="blocksDescendants"放在你拥有的LinearLayout或RelativeLayout中。

Answer 2

你能显示清单吗？如果是，那么请显示layout文件，其中包含TextView以显示列表中的项目。

在这种情况下，请尝试从TextView删除isTextSelectable。

检查是否有一些愚蠢的错误，就像我几个月前从这里做的那样：

onItemClick in ListView doesn't work

Answer 3

删除

listshowcase.setClickable(true);

来自ShowCases的这一行。然后再试一次。

我希望这会对你有所帮助。如果没有，请告诉我。

Answer 4

为从适配器返回的每个视图添加一个OnClickListener。

ListView项目在Android中无法点击
