android–ListView setOnItemClickListener无法正常工作

概述就像标题所说,我的setOnItemClickListener不起作用.我查看了迄今为止我所看到的所有内容,并且无法找到我的错误.这是代码：这是有问题的课程.它不是主类,而是从意图调用：package...;importandroid.os.Bundle;importandroid.app.Activity;importandroid.content.Context;im

就像标题所说,我的setonItemClickListener不起作用.我查看了迄今为止我所看到的所有内容,并且无法找到我的错误.

这是代码：

这是有问题的课程.它不是主类,而是从意图调用：

package...;import androID.os.Bundle;import androID.app.Activity;import androID.content.Context;import androID.content.Intent;import androID.util.Log;import androID.vIEw.Menu;import androID.vIEw.VIEw;import androID.@R_419_5537@.AdapterVIEw;import androID.@R_419_5537@.listadapter;import androID.@R_419_5537@.ListVIEw;public class GroupActivity extends Activity {    String group_ID = "";    Context context;    @OverrIDe    protected voID onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentVIEw(R.layout.activity_group);        context = this;        Intent intent = getIntent();        group_ID = intent.getStringExtra("group_ID");        Log.i("bla", "Launched GroupActivity for group_ID " + group_ID);        final SubAdapter adapter = new SubAdapter(this, group_ID);        ListVIEw lv = (ListVIEw) findVIEwByID(R.ID.ListVIEw1);        lv.setClickable(true);        lv.setAdapter(adapter);        lv.setonItemClickListener(new AdapterVIEw.OnItemClickListener() {            @OverrIDe            public voID onItemClick(AdapterVIEw<?> av, VIEw v, int IDx, long lIDx) {                Log.i("print here", "blaa " + IDx);            }        });    }    @OverrIDe    public boolean onCreateOptionsMenu(Menu menu) {        // Inflate the menu; this adds items to the action bar if it is present.        getMenuInflater().inflate(R.menu.main, menu);        return true;    }}

这是SubAdapter类：

package...;import java.util.ArrayList;import java.util.Date;import java.util.HashMap;import java.util.List;import androID.app.Activity;import androID.content.Context;import androID.content.Intent;import androID.graphics.Bitmap;import androID.graphics.BitmapFactory;import androID.graphics.drawable.BitmapDrawable;import androID.graphics.drawable.Drawable;import androID.text.format.DateUtils;import androID.util.Log;import androID.vIEw.LayoutInflater;import androID.vIEw.VIEw;import androID.vIEw.VIEwGroup;import androID.@R_419_5537@.BaseAdapter;import androID.@R_419_5537@.ImageVIEw;import androID.@R_419_5537@.TextVIEw;public class SubAdapter extends BaseAdapter {    private static final int thumb_wIDth = 128;    private static final int thumb_hight = 128;    private static Bitmap default_thumb = null;    private static LayoutInflater inflater = null;    private final String group_ID_;    private final Activity activity;    private final SubAdapter t = this;    // used to keep selected position in ListVIEw    private int selectedPos = -1;   // init value for not-selected    public SubAdapter(Activity a, final String group_ID) {        Drawable d = a.getResources().getDrawable(R.drawable.ic_contact_picture);        default_thumb = ((BitmapDrawable) d).getBitmap();        activity = a;        group_ID_ = group_ID;        inflater = (LayoutInflater) activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);    }    @OverrIDe    public VIEw getVIEw(int IDx, VIEw convertVIEw, VIEwGroup parent) {        Log.i("bla2", "getting vIEw with index " + IDx);        VIEw vi = convertVIEw;        if (convertVIEw == null) {            vi = inflater.inflate(R.layout.sub_List_item, null);            vi.setClickable(true);        }        TextVIEw tv1 = (TextVIEw)vi.findVIEwByID(R.ID.textVIEw1);        TextVIEw tv2 = (TextVIEw)vi.findVIEwByID(R.ID.textVIEw2);        ImageVIEw img = (ImageVIEw)vi.findVIEwByID(R.ID.imageVIEw1);        tv1.setText("first name" + " " + "last name");        tv2.setText("some date");        // put thumbnail        Bitmap thumb = default_thumb;        img.setimageBitmap(thumb);        Log.i("bla3", "index is " + IDx + "selected index is " + selectedPos);        if(selectedPos == IDx){            Log.i("bla4", "insIDe if");         }              return vi;    }    public voID setSelectedposition(int pos){    selectedPos = pos;         // inform the vIEw of this change         notifyDataSetChanged();    }    @OverrIDe    public voID notifyDataSetChanged() {        super.notifyDataSetChanged();    }}

这是activity_group xml：

 <relativeLayout xmlns:androID="http://schemas.androID.com/apk/res/androID"    xmlns:tools="http://schemas.androID.com/tools"    androID:layout_wIDth="match_parent"    androID:layout_height="match_parent"    androID:paddingBottom="@dimen/activity_vertical_margin"    androID:paddingleft="@dimen/activity_horizontal_margin"    androID:paddingRight="@dimen/activity_horizontal_margin"    androID:paddingtop="@dimen/activity_vertical_margin"    tools:context=".GroupActivity" >    <ListVIEw        androID:ID="@+ID/ListVIEw1"        androID:layout_wIDth="match_parent"        androID:layout_height="wrap_content"        androID:clickable="true"        androID:focusableIntouchMode="false"        androID:focusable="false" >    </ListVIEw></relativeLayout>

这是sub_List_item xml：

<?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:clickable="true"    androID:focusable="false"     androID:focusableIntouchMode="false">    <ImageVIEw        androID:ID="@+ID/imageVIEw1"        androID:layout_wIDth="wrap_content"        androID:layout_height="wrap_content"        androID:layout_alignParentleft="true"        androID:layout_alignParenttop="true"        androID:layout_margin="6dp"        androID:src="@drawable/ic_launcher" />    <TextVIEw        androID:ID="@+ID/textVIEw1"        androID:layout_wIDth="wrap_content"        androID:layout_height="wrap_content"        androID:layout_alignParenttop="true"        androID:layout_margin="6dp"        androID:layout_toleftOf="@+ID/togglebutton1"        androID:layout_toRightOf="@+ID/imageVIEw1"        androID:text="some text"        androID:textAppearance="?androID:attr/textAppearance" />    <TextVIEw        androID:ID="@+ID/textVIEw2"        androID:layout_wIDth="wrap_content"        androID:layout_height="wrap_content"        androID:layout_alignleft="@+ID/textVIEw1"        androID:layout_below="@+ID/textVIEw1"        androID:layout_toleftOf="@+ID/togglebutton1"        androID:text="more text"        androID:textAppearance="?androID:attr/textAppearance" />    <Togglebutton        androID:ID="@+ID/togglebutton1"        androID:layout_wIDth="wrap_content"        androID:layout_height="wrap_content"        androID:layout_alignParenttop="true"        androID:layout_margin="6dp"        androID:text="present" /></relativeLayout>

除了点击监听器之外,其他一切似乎都有效. SubAdapter正确打开并填充列表.
基本上我正在寻找的是获取消息“Log.i(”print here“,”blaa“IDx);”打印 – 它是ListVIEw的setonItemClickListener中的日志(见上图)

如果缺少任何其他相关代码,请与我们联系
谢谢！！！

解决方法:

你可能应该删除这个电话
vi.setClickable(真);在您的SubAdapter类中,因为您的convertVIEw将在onItemClick侦听器之前使用单击.
