如何在列表视图中的可点击列表的行和按钮？
问题描述：
我在我的Android程序中使用了一个listview。如何在列表视图中的可点击列表的行和按钮？
我有行。 1）我有按钮中的自定义行，我想点击按钮，然后打开警报框，这一行点击然后打开新的活动，但只有一个按钮点击不行点击。在这种情况下如何可能。我的代码在下面。
谢谢。
public class AlMessagesAdapter extends ArrayAdapter<DtoAllMessages> {
private LayoutInflater inflator;
private ArrayList<DtoAllMessages> userlist;
public AlMessagesAdapter(Activity context, ArrayList<DtoAllMessages> list) {
super(context, R.layout.custom_list, list);
this.userlist = list;
inflator = context.getLayoutInflater();
}
@Override
public View getView(final int position, View convertView, ViewGroup parent) {
ViewHolder holder = null;
if (convertView == null) {
convertView = inflator.inflate(R.layout.custom_list, null);
holder = new ViewHolder();
holder.title = (TextView) convertView.findViewById(R.id.tvName);
holder.date_cr = (TextView) convertView.findViewById(R.id.tvDate);
holder.img = (ImageView)convertView.findViewById(R.id.ivIcon);
holder.tokenBtn = (Button)convertView.findViewById(R.id.tokenBtn);
convertView.setTag(holder);
convertView.setTag(R.id.tvName, holder.title);
convertView.setTag(R.id.tvDate, holder.date_cr);
convertView.setTag(R.id.ivIcon,holder.img);
convertView.setTag(R.id.tokenBtn,holder.tokenBtn);
} else {
holder = (ViewHolder) convertView.getTag();
}
String token = userlist.get(position).getToken();
Log.v("MessageList", "token:" + token);
token = token.substring(0,token.length()-3);
holder.title.setText(userlist.get(position).getName()+"("+token+")");
String type_data = userlist.get(position).getType().toString();
if((type_data.equals("text")) || (type_data.equals("photo")))
{
Log.v("log", " if text photo ");
holder.date_cr.setText(userlist.get(position).getType()+":Received "+userlist.get(position).getCreated_date());
holder.tokenBtn.setVisibility(View.VISIBLE);
list.setItemsCanFocus(true);
}
else if(type_data.equals("out"))
{
Log.v("log", " else out ");
holder.date_cr.setText(userlist.get(position).getType()+":Sent "+userlist.get(position).getCreated_date());
holder.tokenBtn.setVisibility(View.GONE);
}
if(type_data.equals("text"))
{
Log.v("log", " if text ");
holder.img.setBackgroundResource(R.drawable.chatmessage);
}
else if(type_data.equals("photo"))
{
Log.v("log", " ese if photo ");
holder.img.setBackgroundResource(R.drawable.photomessage);
}
else if(type_data.equals("out"))
{
Log.v("log", " ese if out ");
holder.img.setBackgroundResource(R.drawable.outmessafe);
}
if(position%2==0)
{
convertView.setBackgroundResource(R.drawable.whitebackground);
}
else
{
convertView.setBackgroundResource(R.drawable.greybackground);
}
holder.tokenBtn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Log.v("log_tag"," token button clicked");
}
});
return convertView;
}
class ViewHolder {
protected ImageView img;
protected TextView date_cr;
protected TextView title;
protected Button tokenBtn;
}
}
和列表点击事件如下::
list.setOnItemLongClickListener(new OnItemLongClickListener() {
@Override
public boolean onItemLongClick(AdapterView<?> arg0, View arg1,
int position, long arg3) {
// TODO Auto-generated method stub
msg = userLIstArray.get(position).getMessage();
token = userLIstArray.get(position).getToken();
type = userLIstArray.get(position).getType();
int msgId = userLIstArray.get(position).getMessageid();
token = token.substring(0,token.length()-3);
int token_value = Integer.parseInt(token) * 1000;
if(type.equals("text"))
{
Log.v("log", " if in text to Display " + msg + " token "+token);
Intent i = new Intent(MessagesList.this,DisplayPopupActivity.class);
i.putExtra("msg", msg);
i.putExtra("token", token);
i.putExtra("msgid", msgId);
startActivity(i);
}
else if(type.equals("photo"))
{
Log.v("log", " else in IMage to Display " + msg + " token "+token);
Log.v("log","token "+token+" type "+type + " position "+position + "msgId "+ msgId);
Intent i = new Intent(MessagesList.this,DisplayImageActivity.class);
i.putExtra("imgData", msg);
i.putExtra("token", token);
i.putExtra("msgid", msgId);
startActivity(i);
//Log.v("log"," Message" +message);
//Toast.makeText(AllMessageActivity.this, "Message "+message, Toast.LENGTH_LONG).show();
}
return false;
}
});
}

试试这个，
而不是按钮使用TextView。并写onclickListerner至TextView。我在ListView面临同样的问题按钮点击使用textview现在它的工作正常。去尝试一下。

可以使用添加行单击事件：
listView.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(final AdapterView<?> parent, final View view, final int position, long id) {
//go to new activity
});
而且按钮的事件，因为你正在做的..
holder.tokenBtn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Log.v("log_tag"," token button clicked");
//show alert
}
});

感谢您的答复，但我cliked行不工作，我编辑在我的问题在ListView单击事件请检查它。 – crickpatel0024 2013-05-09 09:12:33

内打电话给你clickevent如果条件
if (convertView == null) {
convertView = inflator.inflate(R.layout.custom_list, null);
holder = new ViewHolder();
holder.title = (TextView) convertView.findViewById(R.id.tvName);
holder.date_cr = (TextView) convertView.findViewById(R.id.tvDate);
holder.img = (ImageView)convertView.findViewById(R.id.ivIcon);
holder.tokenBtn = (Button)convertView.findViewById(R.id.tokenBtn);
holder.tokenBtn.setOnClickListener(click);
}
之外创建clicklistner。
private OnClickListener click = new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
// do your stuff here
}
};

感谢您对我的问题的答复！ – crickpatel0024 2013-05-09 09:47:15

在设置OnclickListner
private LayoutInflater inflator;
private ArrayList<DtoAllMessages> userlist;
private Context context; //added
public AlMessagesAdapter(Activity context, ArrayList<DtoAllMessages> list) {
super(context, R.layout.custom_list, list);
this.context=context; //added
this.userlist = list;
inflator = context.getLayoutInflater();
}
@Override
public View getView(final int position, View convertView, ViewGroup parent) {
ViewHolder holder = null;
if (convertView == null) {
convertView = inflator.inflate(R.layout.custom_list, null);
holder = new ViewHolder();
holder.title = (TextView) convertView.findViewById(R.id.tvName);
holder.date_cr = (TextView) convertView.findViewById(R.id.tvDate);
holder.img = (ImageView)convertView.findViewById(R.id.ivIcon);
holder.tokenBtn = (Button)convertView.findViewById(R.id.tokenBtn);
holder.tokenBtn.setOnClickListener((OnClickListener)context); //added portion
convertView.setTag(holder);
convertView.setTag(R.id.tvName, holder.title);
convertView.setTag(R.id.tvDate, holder.date_cr);
convertView.setTag(R.id.ivIcon,holder.img);
convertView.setTag(R.id.tokenBtn,holder.tokenBtn);
} else {
holder = (ViewHolder) convertView.getTag();
}
String token = userlist.get(position).getToken();
Log.v("MessageList", "token:" + token);
token = token.substring(0,token.length()-3);
holder.title.setText(userlist.get(position).getName()+"("+token+")");
String type_data = userlist.get(position).getType().toString();
if((type_data.equals("text")) || (type_data.equals("photo")))
{
Log.v("log", " if text photo ");
holder.date_cr.setText(userlist.get(position).getType()+":Received "+userlist.get(position).getCreated_date());
holder.tokenBtn.setVisibility(View.VISIBLE);
list.setItemsCanFocus(true);
}
else if(type_data.equals("out"))
{
Log.v("log", " else out ");
holder.date_cr.setText(userlist.get(position).getType()+":Sent "+userlist.get(position).getCreated_date());
holder.tokenBtn.setVisibility(View.GONE);
}
if(type_data.equals("text"))
{
Log.v("log", " if text ");
holder.img.setBackgroundResource(R.drawable.chatmessage);
}
else if(type_data.equals("photo"))
{
Log.v("log", " ese if photo ");
holder.img.setBackgroundResource(R.drawable.photomessage);
}
else if(type_data.equals("out"))
{
Log.v("log", " ese if out ");
holder.img.setBackgroundResource(R.drawable.outmessafe);
}
if(position%2==0)
{
convertView.setBackgroundResource(R.drawable.whitebackground);
}
else
{
convertView.setBackgroundResource(R.drawable.greybackground);
}
/*holder.tokenBtn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Log.v("log_tag"," token button clicked");
}
});*/
return convertView;
}
class ViewHolder {
protected ImageView img;
protected TextView date_cr;
protected TextView title;
protected Button tokenBtn;
}
}
和你的主类
public Main extends Activity implements OnClickListener{
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.casual_layout);
Button tokenBtn=(Button)findViewById(R.id.tokenBtn);
tokenBtn.setOnClickListener(this);
}
public void onClick(View v) {
switch (v.getId()) {
case R.id.tokenBtn:
//Write a code here to execute alertdialog
Log.d("ALERT HERE","ALERT HERE");
break;
}
}

您的适配器类，如果你想使用的Button代替TextView设置
android:focusable="false"
到您的Button
感谢Murali我会尝试。 – crickpatel0024 2013-05-09 09:38:02
感谢Murali解决了这个问题！ – crickpatel0024 2013-05-09 09:45:43
但你可以使用按钮，如果你不得不... – Cjames 2013-05-09 09:53:35
