Android中ListView实现子控件点击事件后ListView点击事件失效解决办法

/article/1777023.html

最近有人问我，在Android里：

在自定义listView里面有按钮，然后setItemClickListener时不响应，网上很多关于这个的，但我都试过，貌似都解决不了。

其实刚开始学Android接触ListView时我也遇到此问题，在网上到处搜也难以找到相关解决方案，原因之一是网上原创文章少，转载居多，很多文章都雷同；原因之二在于自己英语不好，不敢上外文论坛去找。

后来经过自己的慢慢摸索终于解决了这个问题。

当朋友问我时，我一番简单讲解加几张代码截图就给他解决问题啦~

废话不多说，先上源代码：源代码

代码片段：

main.xml

[html] view
plaincopyprint?

<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:background="@drawable/background" >



<ListView

android:id="@+id/lv_list"

android:layout_width="fill_parent"

android:layout_height="fill_parent"

android:layout_alignParentLeft="true"

android:layout_below="@+id/numxback"

android:cacheColorHint="#00000000"

android:drawSelectorOnTop="false"

android:fadingEdge="none"

android:fastScrollEnabled="true"

android:focusable="false"

android:divider="@null"

android:focusableInTouchMode="true"

android:listSelector="@drawable/itemselected" />



</RelativeLayout>

在main布局里加入了一个列表控件，ListView，它的各个属性在此处不是重点，这里就不多说，看不懂的读者自己去网上搜吧！

datalist.xml

[html] view
plaincopyprint?

<?xml version="1.0" encoding="utf-8"?>

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:id="@+id/widget_datalist"

android:layout_width="fill_parent"

android:layout_height="fill_parent"

android:descendantFocusability="blocksDescendants">



<TextView

android:id="@+id/tv_num"

android:layout_width="wrap_content"

android:layout_height="60px"

android:layout_centerVertical="true"

android:background="@drawable/number"

android:gravity="center"

android:paddingLeft="5px"

android:paddingRight="8px"

android:textColor="@android:color/white"

android:textSize="24sp" />



<ImageButton

android:id="@+id/ib_edit"

android:layout_width="60px"

android:layout_height="60px"

android:layout_alignParentRight="true"

android:background="@drawable/edit"

<span style="color:#ff0000">android:onClick="OnItemEditClick"

</span> android:paddingRight="5px" />



<TextView

android:id="@+id/tv_numx"

android:layout_width="150px"

android:layout_height="60px"

android:layout_toRightOf="@+id/tv_num"

android:background="@drawable/number"

android:gravity="center_vertical"

android:singleLine="true"

android:textColor="@android:color/white"

android:textSize="24sp" />



<TextView

android:id="@+id/tv_numy"

android:layout_width="150px"

android:layout_height="60px"

android:layout_toRightOf="@id/tv_numx"

android:layout_toLeftOf="@id/ib_edit"

android:background="@drawable/number"

android:gravity="center_vertical"

android:singleLine="true"

android:textColor="@android:color/white"

android:textSize="24sp" />



</RelativeLayout>

列表控件单项布局，在里面加入了三个TextView，一个ImageButton，显示时三个TextView 在前面，最后一个ImageButton。

之前说到的按钮点击事件在Activity里用button.setOnClickListener的方式实现时会屏蔽/占用ListView单项单击事件，这里就在布局里加了一个android:onClick="OnItemEditClick"，用于绑定按钮点击事件，然后在java代码中实现这个方法，记得须有一个View类型的参数。

MainActivity.java

[java] view
plaincopyprint?

package com.test.customlistview;



import java.util.ArrayList;

import java.util.HashMap;



import android.os.Bundle;

import android.os.Handler;

import android.os.Message;

import android.app.Activity;

import android.app.AlertDialog;

import android.content.DialogInterface;

import android.content.DialogInterface.OnClickListener;

import android.view.View;

import android.widget.AdapterView;

import android.widget.ImageButton;

import android.widget.ListView;

import android.widget.RelativeLayout;

import android.widget.SimpleAdapter;

import android.widget.TextView;

import android.widget.Toast;

import android.widget.AdapterView.OnItemLongClickListener;



public class MainActivity extends Activity {



ListView dataListView;

SimpleAdapter listAdapter;

ArrayList<HashMap<String, Object>> list;

private int location;

Handler mHandler = new Handler() {



@Override

public void handleMessage(Message msg) {

if (msg.arg1 == 1) {



} else if (msg.arg1 == 2) {



} else if (msg.arg1 == 4) {

if (msg.what == 1) {

dataListView.getChildAt(msg.arg2).setBackgroundResource(

R.drawable.itemback);

}

}

super.handleMessage(msg);

}

};

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

dataListView = (ListView) findViewById(R.id.lv_list);

list = new ArrayList<HashMap<String, Object>>();

int count = 20;

HashMap<String, Object> map;

for (int i = 1; i <= count; i++) {

map = new HashMap<String, Object>();

map.put("num", i+ "");

map.put("a1", "²=");

map.put("a2", ""+i*i);

list.add(map);

}

listAdapter = new SimpleAdapter(this, list, R.layout.datalist,

new String[] { "num", "a1", "a2" }, new int[] { R.id.tv_num,

R.id.tv_numx, R.id.tv_numy });

dataListView.setAdapter(listAdapter);

dataListView.setOnItemLongClickListener(new OnItemLongClickListener() {

public boolean onItemLongClick(AdapterView<?> arg0, View view,

int position, long id) {

location = position;

final View nowView = (View) view.findViewById(R.id.ib_edit);

Toast.makeText(getBaseContext(), "location=" + location, 2000)

.show();

OnClickListener listener = new DialogInterface.OnClickListener() {

public void onClick(DialogInterface dialog, int which) {

if (which == 0) {

Toast.makeText(getBaseContext(), "编辑", Toast.LENGTH_LONG).show();

} else if (which == 1) {

Toast.makeText(getBaseContext(), "删除", Toast.LENGTH_LONG).show();

}

}

};

dataListView.getChildAt(location).setBackgroundResource(

R.drawable.item_frame);

Message message = new Message();

message.arg1 = 4;

message.arg2 = location;

message.what = 1;

mHandler.sendMessageDelayed(message, 500);

String[] Menu = { "编辑", "删除" };



new AlertDialog.Builder(MainActivity.this).setItems(Menu,

listener).show();

return false;

}

});

}



public void OnItemEditClick(View v) {

RelativeLayout layout = (RelativeLayout) v.getParent();

TextView tv1=(TextView)layout.findViewById(R.id.tv_num);

TextView tv2=(TextView)layout.findViewById(R.id.tv_numx);

TextView tv3=(TextView)layout.findViewById(R.id.tv_numy);

ImageButton ib=(ImageButton)layout.findViewById(R.id.ib_edit);

String str="按钮"+tv1.getText()+"点击啦\n"+tv1.getText()+tv2.getText()+tv3.getText();

Toast.makeText(getBaseContext(), str, Toast.LENGTH_LONG).show();

}

}

OnItemEditClick(View v)方法中通过v.getParent();找到她的容器控件，前面的(RelativeLayout)根据你自己的布局里的容器控件而定。然后即可使用该容器控件找到他的所有自控件，然后读者想干嘛就干嘛啦~

上面的dataListView.setOnItemLongClickListener实现ListView的item长按事件，我在这里加了一个显示两条菜单的对话框，用于进行其他操作，如编辑、删除等。

这里也可以实现ListView的点击事件，PS：这段代码是后来加的，直接嵌入源代码中即可，已调试无误。



[java] view
plaincopyprint?

dataListView.setOnItemClickListener(new OnItemClickListener() {



@Override

public void onItemClick(AdapterView<?> arg0, View view, int arg2,

long arg3) {

TextView tv=(TextView)view.findViewById(R.id.tv_num);

Toast.makeText(getBaseContext(), "您点击了第" + tv.getText()+"行", 2000).show();

}

});

修改后的MainActivity.java代码如下

[java] view
plaincopyprint?

package com.test.customlistview;



import java.util.ArrayList;

import java.util.HashMap;



import android.os.Bundle;

import android.os.Handler;

import android.widget.ImageButton;

import android.widget.ListView;

import android.widget.RelativeLayout;

import android.widget.SimpleAdapter;

import android.widget.TextView;

import android.widget.Toast;

import android.widget.AdapterView.OnItemLongClickListener;



public class MainActivity extends Activity {

Handler mHandler = new Handler() {



@Override

public void handleMessage(Message msg) {

if (msg.arg1 == 1) {



} else if (msg.arg1 == 2) {



} else if (msg.arg1 == 4) {

if (msg.what == 1) {

dataListView.getChildAt(msg.arg2).setBackgroundResource(

R.drawable.itemback);

}

}

super.handleMessage(msg);

}

};

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

dataListView = (ListView) findViewById(R.id.lv_list);

list = new ArrayList<HashMap<String, Object>>();

int count = 20;

HashMap<String, Object> map;

for (int i = 1; i <= count; i++) {

map = new HashMap<String, Object>();

map.put("num", i+ "");

map.put("a1", "²=");

map.put("a2", ""+i*i);

list.add(map);

}

listAdapter = new SimpleAdapter(this, list, R.layout.datalist,

new String[] { "num", "a1", "a2" }, new int[] { R.id.tv_num,

R.id.tv_numx, R.id.tv_numy });

dataListView.setAdapter(listAdapter);

dataListView.setOnItemClickListener(new OnItemClickListener() {



@Override

public void onItemClick(AdapterView<?> arg0, View view, int arg2,

long arg3) {

TextView tv=(TextView)view.findViewById(R.id.tv_num);

Toast.makeText(getBaseContext(), "您点击了第" + tv.getText()+"行", 2000).show();

}

});

dataListView.setOnItemLongClickListener(new OnItemLongClickListener() {

public boolean onItemLongClick(AdapterView<?> arg0, View view,

int position, long id) {

location = position;

final View nowView = (View) view.findViewById(R.id.ib_edit);

Toast.makeText(getBaseContext(), "location=" + location, 2000)

.show();

OnClickListener listener = new DialogInterface.OnClickListener() {

public void onClick(DialogInterface dialog, int which) {

if (which == 0) {

Toast.makeText(getBaseContext(), "编辑", Toast.LENGTH_LONG).show();

} else if (which == 1) {

Toast.makeText(getBaseContext(), "删除", Toast.LENGTH_LONG).show();

}

}

};

dataListView.getChildAt(location).setBackgroundResource(

R.drawable.item_frame);

Message message = new Message();

message.arg1 = 4;

message.arg2 = location;

message.what = 1;

mHandler.sendMessageDelayed(message, 500);

String[] Menu = { "编辑", "删除" };



new AlertDialog.Builder(MainActivity.this).setItems(Menu,

listener).show();

return false;

}

});

}



public void OnItemEditClick(View v) {

RelativeLayout layout = (RelativeLayout) v.getParent();

TextView tv1=(TextView)layout.findViewById(R.id.tv_num);

TextView tv2=(TextView)layout.findViewById(R.id.tv_numx);

TextView tv3=(TextView)layout.findViewById(R.id.tv_numy);

ImageButton ib=(ImageButton)layout.findViewById(R.id.ib_edit);

String str="按钮"+tv1.getText()+"点击啦\n"+tv1.getText()+tv2.getText()+tv3.getText();

Toast.makeText(getBaseContext(), str, Toast.LENGTH_LONG).show();

}

}

注：这个小demo根本算不上自定义ListView，只是稍微给他丰富了一下子元素，以实现更好看的界面效果，当然，我这个不好看哈，只是为了写博文的演示罢了。

代码都贴出来了，说明文字不多，但应该基本说清楚了，读者慢慢看吧，主要还是研读代码，尝试着慢慢修改变成自己的并从中学到一些东西才是重点！
