这是我的Java类在此,我在访问列表中,但无法点击

 公共类展示延伸活动{
  ListView控件listshowcase;
EditText上搜索;
  ListViewAdapter适配器;

   @覆盖
保护无效的onCreate(包savedInstanceState){
    // TODO自动生成方法存根
       super.onCreate(savedInstanceState);
    的setContentView(R.layout.screen4);

    listshowcase =(ListView控件)findViewById(R.id.liCases);
    适配器=新ListViewAdapter(本);
      listshowcase.setAdapter(适配器);
    listshowcase.setClickable(真正的);
    listshowcase.setOnItemClickListener(新AdapterView.OnItemClickListener(){

        @覆盖
        公共无效onItemClick(适配器视图<>为arg0,视图中查看,INT ARG2,
                长ARG3){

            字符串名称=((TextView中)view.findViewById(R.id.name))的getText()的toString()。
            串成本=((TextView中)view.findViewById(R.id.email))的getText()的toString()。

            in.putExtra(FF,介绍);
            in.putExtra(FFF,身份证);
            startActivity(在);
        }
     });


    搜索=(EditText上)findViewById(R.id.etCaseSeacrh);

    sea​​rch.addTextChangedListener(新TextWatcher(){

        @覆盖
        公共无效onTextChanged(CharSequence中,诠释开始,诠释之前,诠释计数){
            //调用回来当前字符的适配器过滤器

        }

        @覆盖
        公共无效beforeTextChanged(CharSequence中,诠释开始,诠释计数,之后INT){
        }

                @覆盖
        公共无效afterTextChanged(编辑为arg0){
            // TODO自动生成方法存根

         }
    });
  }
 
为什么点击LISTVIEW中的最后一个ITEM就会弹出一个对话框

这就是定制getview Listadapter类

  @覆盖
    公共查看getView(最终诠释paramInt,查看paramView,
         最后的ViewGroup paramViewGroup){
      // TODO自动生成方法存根
      LayoutInflater充气= activity.getLayoutInflater();
      如果(paramView == NULL){
         鉴于=新ViewHolder();
         paramView = inflator.inflate(R.layout.list_item,NULL);

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

      } 其他 {
         鉴于=(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(假); * /
     /*view.setOnClickListener(myClickListener);*/
     view.name.setFocusable(假);
     view.email.setFocusable(假);
     view.mobile.setFocusable(假);
     view.id.setFocusable(假);

    返回paramView;
 }
 

解决方案

好吧,你在那里有一个按钮。在您的list_item可XML认沽安卓:在LinearLayout中或RelativeLayout的descendantFocusability =blocksDescendants

In this ListVIew is not clickable, i want to perform an action on item click but i do not know why this is not clickable, i have also checked in debugging the controller is not gone in itemclicklistener, please help Thanks

design file :

  <?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:text="New Case" />

</RelativeLayout>

This is my java class in this i am accessing list but is not clickable

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

         }
    });
  }

and this is getview of custom Listadapter class

@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;
 }

解决方案

Ok you have a button in there. In your list_item xml put android:descendantFocusability="blocksDescendants" in the LinearLayout or RelativeLayout you have.
