【问题描述】：
我创建了一个自定义listview，它的左侧有一个ImageView，右侧有一个TextView。并使用actionbar 上下文菜单实现多选Listview。
问题是，当我长按一个项目时，它没有被突出显示。
这是我在ListFragment 中设置listview 的方法
PasswordsFragment.java
package mohd.itcs.safewallet;
import android.os.Bundle;
import android.support.v4.app.ListFragment;
import android.view.ActionMode;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.AbsListView.MultiChoiceModeListener;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemLongClickListener;
import android.widget.ListView;
public class PasswordsFragment extends ListFragment {
private String titles[] = { "item1", "item2", "item3" };
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setListAdapter(new CustomPasswordsList(getActivity(), titles));
}
@Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
/*
* Setup Multiple Selection Mode
*/
getListView().setChoiceMode(ListView.CHOICE_MODE_MULTIPLE_MODAL);
getListView().setOnItemLongClickListener(new OnItemLongClickListener() {
@Override
public boolean onItemLongClick(AdapterView<?> listview, View item,
int position, long id) {
getListView().setItemChecked(position, true);
return true;
}
});
getListView().setMultiChoiceModeListener(new MultiChoiceModeListener() {
@Override
public boolean onActionItemClicked(ActionMode arg0, MenuItem arg1) {
// TODO Auto-generated method stub
return false;
}
/*
* Inflate Actionbar Menu for Passwords Multiple Selection
*/
@Override
public boolean onCreateActionMode(ActionMode arg0, Menu menu) {
getActivity().getMenuInflater().inflate(
R.menu.passwords_context_menu, menu);
return true;
}
@Override
public void onDestroyActionMode(ActionMode arg0) {
}
@Override
public boolean onPrepareActionMode(ActionMode arg0, Menu arg1) {
return false;
}
@Override
public void onItemCheckedStateChanged(ActionMode actionMode,
int position, long id, boolean arg3) {
/*
* Change Title bar to number of selection
*/
int checkedItems = getListView().getCheckedItemCount();
actionMode.setTitle(String.valueOf(checkedItems) + " Selected");
}
});
}
}
CustomPasswordsList.java
package mohd.itcs.safewallet;
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.ImageView;
import android.widget.TextView;
public class CustomPasswordsList extends ArrayAdapter<String> {
private final Context context;
private final String values[];
public CustomPasswordsList(Context context, String[] values)
{
super(context, R.layout.password_list_item, values);
this.context = context;
this.values = values;
}
public View getView(int position, View convertView, ViewGroup parent)
{
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View rowView = inflater.inflate(R.layout.password_list_item, parent, false);
TextView passwordTitle = (TextView) rowView.findViewById(R.id.textView_passwordTitle);
ImageView passwordIcon = (ImageView) rowView.findViewById(R.id.imageView_passwordIcon);
passwordTitle.setText(values[position]);
passwordIcon.setImageResource(R.drawable.facebook);
return rowView;
}
}
密码列表项
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:weightSum="1"
android:orientation="horizontal" >
<ImageView
android:id="@+id/imageView_passwordIcon"
android:layout_height="60dp"
android:contentDescription="@string/imageView_passwordIcon"
android:layout_width="60dp" />
<TextView
android:id="@+id/textView_passwordTitle"
android:layout_height="wrap_content"
android:layout_width="0dp"
android:paddingLeft="10dp"
android:paddingTop="15dp"
android:textSize="16sp"
android:textColor="#000000"
android:layout_weight="1" />
</LinearLayout>
