Question

大家好我拥有自定义网格视图，其中包含imageButton和textView，如下所示

enter image description here

这里我使用了imageButton ..问题是网格不可点击..但如果我在这里使用imageView它工作正常但UI不合适。

这是我的布局

 <?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" 
    android:gravity="center"
    android:padding="5dp"
    >

    <ImageButton
        android:id="@+id/profilePic"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/newlocation" 
        android:background="@drawable/btnbackground"
        />

    <TextView
        android:id="@+id/SpeakerName"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:gravity="center"
        android:textSize="15sp"
        android:text="Some Speaker"
        />

这是我的适配器

    package com.tt.cc;

import java.util.List;

import android.content.Context;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.TextView;

public class SavedConferencesGridAdapter extends ArrayAdapter<String>{


    Context mContext;
    List<String> confernceList;

    public SavedConferencesGridAdapter(Context context, int textViewResourceId, List<String> confernceList) 
    {

        super(context,textViewResourceId,confernceList);
        this.confernceList =  confernceList;
        this.mContext = context;
        Log.e("TAG", confernceList.size()+"");
    }

    int[] picIds = new int[] { R.drawable.newschedule,R.drawable.newexhibitors,
                                R.drawable.newsponsers, R.drawable.newlocation,
                                R.drawable.newfavourites, R.drawable.newreminder,R.drawable.info,R.drawable.info,R.drawable.info,R.drawable.info,R.drawable.info,R.drawable.info };


    @Override
    public int getCount() {
        // TODO Auto-generated method stub
        return confernceList.size();
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        // TODO Auto-generated method stub
        View v;



        if(convertView==null){
            LayoutInflater li = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            v = li.inflate(R.layout.entity, null);
            TextView tv = (TextView)v.findViewById(R.id.SpeakerName);
            tv.setText("tt");
            /*ImageView iv = (ImageView) v.findViewById(R.id.profilePic);
            iv.setImageResource(picIds[position]);*/

        }
        else
        {
            v = convertView;
        }
        return v;
    }



}

这是我的活动

 public class SavedConferencesActivity extends Activity{

    GridView confereneceGridView;
    ArrayAdapter<String> conferneceAdapter;
    Button btnUpdate;

    List<String> conferenceList;
    TextView txtHeading;
    Boolean result = false;

    @Override
    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);


    }


    protected void onStart() {
        super.onStart();
        setContentView(R.layout.homegridlayout);
        initialize();

        confereneceGridView.setOnItemClickListener(new OnItemClickListener() {

            @Override
            public void onItemClick(AdapterView<?> parent, View view,
                    int position, long id) {

                Toast.makeText(SavedConferencesActivity.this, conferenceList.get(position)+"", Toast.LENGTH_SHORT).show();


    }

    @Override
    protected void onResume() {
        // TODO Auto-generated method stub
        super.onResume();

        conferneceAdapter = new SavedConferencesGridAdapter(this, android.R.layout.simple_list_item_1, conferenceList);
        confereneceGridView.setAdapter(conferneceAdapter);
    }


    private void initialize() {


        confereneceGridView = (GridView) findViewById(R.id.gridOfConference);
        btnUpdate = (Button) findViewById(R.id.btnUpdate);
        txtHeading = (TextView) findViewById(R.id.txtTag);

        conferenceList = new ArrayList<String>();
        conferenceList.add("AA");
        conferenceList.add("BB");
        conferenceList.add("CC");

        if (conferenceList.size() == 0)
            txtHeading.setText("No conferences saved");
        else
            txtHeading.setText("Selected Conferences");



    }




}

请帮我解决这个问题。或者，如果有任何其他选择..

Answer 1

简单。为ImageButton提供此属性，

android:focusable="false"

当网格中存在可聚焦元素时，通常会发生此问题。（例如：按钮，ImageButton等）。

Answer 2

默认情况下，此ImageButton的原因是可点击且可对焦，因此Focus和click事件永远不会进入ItemView。

设置属性

android:focusable-"false"

和

android:clickable="false"

Answer 3

您的项目布局应为：

<LinearLayout ...
    android:descendantFocusability="blocksDescendants">
<ImageButton ...
    android:focusable="false"
    android:focusableInTouchMode="false"/>
</LinearLayout>

不要忘记适配器中的ImageButton的setOnClickListener。

Answer 4

你的适配器类中的

，在返回视图“v”之前，将“onClickListener”添加到“v”

 v.setOnClickListener(new OnClickListener() {           
        @Override
        public void onClick(View v) {
                Toast.makeText(context, position, Toast.LENGTH_SHORT).show();
        }
 });
