弹出对话框中的ListView问题 防止对话框被关掉的代码

本帖最后由 李少卿 于 2012-8-14 10:18 编辑 AlertDialog.Builder.setAdapter方法可以给弹出的对话框设置个ListView 我想点击这个ListView中的某几项给应用做一些设置 但是点击某一项，事件响应后，对话框就关掉了 就是说，点击ListView中的 某一项，效果跟点击下面的确定和取消是一样的 对话框代码如下： final AlertDialog.Builder builder = new AlertDialog.Builder( DetailedInterfaceActivity. this ); builder.setTitle( "请选择要下载的内容" ); final boolean [] bol = new boolean [course.length]; final SelectAdapter sa = new SelectAdapter(course, bol); builder.setAdapter(sa, new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { bol[which] = !bol[which]; sa.notifyDataSetChanged(); } }) .setPositiveButton( "下载" , new DialogInterface.OnClickListener() { @SuppressWarnings ( "unchecked" ) public void onClick( //此处是下载处理的代码 }) .setNegativeButton( "取消" , new DialogInterface.OnClickListener() { public void onClick( DialogInterface dialog, int which) { } }); builder.create().show(); BaseAdapter的代码： class SelectAdapter extends BaseAdapter { String course[]; boolean value[]; CheckBox check[]; SelectAdapter(String course[], boolean value[]){ this .course = course; this .value = value; } @Override public int getCount() { check = new CheckBox[course.length]; return course.length; } @Override public CheckBox getItem( int position) { return check[position]; } @Override public long getItemId( int position) { return position; } @Override public View getView( int position, View convertView, ViewGroup parent) { LayoutInflater laInflater = (LayoutInflater) DetailedInterfaceActivity. this .getSystemService(android.app.Service.LAYOUT_INFLATER_SERVICE); convertView = laInflater.inflate(R.layout.select_layout, null ); TextView black = (TextView) convertView.findViewById(R.id.select_black_7531); TextView blue = (TextView) convertView.findViewById(R.id.select_blue_7532); CheckBox check = (CheckBox) convertView.findViewById(R.id.select_checkBox_7533); this .check[position] = check; black.setText(course[position].subSequence( 0 , 5 )); if (- 1 != course[position].indexOf( "###" )){ check.setVisibility(View.GONE); blue.setVisibility(View.VISIBLE); blue.setText( "已下载" ); } else { check.setChecked(value[position]); } return convertView; } } BaseAdapter调用的布局文件： <?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= "wrap_content" android:background= "#ffffff" android:orientation= "horizontal" > <TextView android:id= "@+id/select_black_7531" android:layout_width= "wrap_content" android:layout_height= "wrap_content" android:textColor= "@color/black" android:layout_marginLeft= "15dip" android:layout_marginTop= "15dip" android:layout_marginBottom= "5dip" android:layout_centerVertical= "true" android:textSize= "20sp" android:text= "第 1 课" /> <TextView android:id= "@+id/select_blue_7532" android:layout_width= "wrap_content" android:layout_height= "wrap_content" android:textColor= "@color/blue" android:textSize= "16sp" android:layout_alignParentRight= "true" android:layout_centerVertical= "true" android:layout_marginRight= "10dip" android:visibility= "gone" android:text= "已下载" /> <CheckBox android:id= "@+id/select_checkBox_7533" android:layout_width= "wrap_content" android:layout_height= "wrap_content" android:layout_alignParentRight= "true" android:layout_centerVertical= "true" android:layout_marginRight= "10dip" /> </RelativeLayout>

 

 

 

 

已经解决了 防止对话框被关掉的代码 try { Field field = dialog.getClass().getSuperclass().getDeclaredField( "mShowing" ); field.setAccessible( true ); field.set(dialog, false ); } catch (Exception e) { e.printStackTrace(); } 设置可以被关掉的代码： try { Field field = dialog.getClass().getSuperclass().getDeclaredField( "mShowing" ); field.setAccessible( true ); field.set(dialog, true ); } catch (Exception e) { e.printStackTrace(); }
