与自定义行布局多选警报对话框 [英] Multiple choice alert dialog with custom row layout
问题描述
我需要与多项选择题创建AlertDialog但我遇到了一些麻烦试图自定义布局文件设置为内部的ListView。
有关单项选择的项目我使用一个构造函数一个ListAdapter作为参数，这样我可以设置每行的适当布局资源：
builder.setSingleChoiceItems（新ArrayAdapter＆LT;串GT;（getActivity（）
R.layout.list_item_single_choice_answer，物品），checkedItem，
新DialogInterface.OnClickListener（）{ @覆盖
公共无效的onClick（DialogInterface对话，诠释它）{
checkedItem =其中;
toggleEditTextAnswer（checkedItem ==（items.length - 1））;
dialog.dismiss（）;
}
}）;
问题是，有没有为构造的 setMultiChoiceItems 创建多重选择列表时，接受一个ListAdapter作为参数。</ P>
我需要为每行设置自定义布局，因为我用绘选择器设置行背景和文本颜色。
任何想法？

好了，我知道我应该创建一个自定义对话框，但现在我没有时间去做......所以这是我怎么黑了这问题：
AlertDialog.Builder建设者=新AlertDialog.Builder（getActivity（））;
//设置适配器
builder.setAdapter（
新ArrayAdapter＆LT;串GT;（getActivity（）
R.layout.list_item_multiple_choice_answer，物品），NULL）
//设置操作按钮
.setPositiveButton（android.R.string.ok，
新DialogInterface.OnClickListener（）{
@覆盖
公共无效的onClick（DialogInterface对话，诠释的id）{
dialog.dismiss（）;
}
}）; AlertDialog alertDialog = builder.create（）; ListView控件的ListView = alertDialog.getListView（）;
listView.setAdapter（新ArrayAdapter＆LT;串GT;（getActivity（）
R.layout.list_item_multiple_choice_answer，物品））;
listView.setChoiceMode（ListView.CHOICE_MODE_MULTIPLE）;
listView.setOnItemClickListener（新AdapterView.OnItemClickListener（）{ @覆盖
公共无效onItemClick（适配器视图＆LT;＆GT;母公司，观景，INT位置，长的id）{
CheckedTextView checkedTextView =（CheckedTextView）视图。
checkedItems [位置] = checkedTextView.isChecked（）！;
}
}）;
listView.setDivider（NULL）;
listView.setDividerHeight（-1）; alertDialog.setOnShowListener（新DialogInterface.OnShowListener（）{ @覆盖
公共无效昂秀（DialogInterface对话）{
setCheckedItems（（（AlertDialog）对话框）.getListView（））;
}
}）; alertDialog.show（）;
首先，我设置适配器的项目和而不是调用setMultiChoiceItems我从对话取得的ListView对象，然后配置它自己。
I need to create an AlertDialog with multiple choice items but I'm having some trouble trying to set a custom layout file to the internal ListView.
For single choice items I use a constructor that takes a ListAdapter as parameter and this way I can set the proper layout resource for each row:
builder.setSingleChoiceItems(new ArrayAdapter<String>(getActivity(),
R.layout.list_item_single_choice_answer, items), checkedItem,
new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
checkedItem = which;
toggleEditTextAnswer(checkedItem == (items.length - 1));
dialog.dismiss();
}
});
The problem is that there's no constructor for setMultiChoiceItems that accepts a ListAdapter as parameter when creating a multiple choice list.
I need to set a custom layout for each row because I use drawable selectors for setting the row background and text color.
Any ideas?
PS. here is the AlertDialog source code for more information. https://android.googlesource.com/platform/frameworks/base.git/+/android-4.2.2_r1/core/java/android/app/AlertDialog.java
Well, I know I should create a custom Dialog but right now I don't have the time to do it ... so this is how I hacked this problem:
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
// Set the adapter
builder.setAdapter(
new ArrayAdapter<String>(getActivity(),
R.layout.list_item_multiple_choice_answer, items), null)
// Set the action buttons
.setPositiveButton(android.R.string.ok,
new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int id) {
dialog.dismiss();
}
});
AlertDialog alertDialog = builder.create();
ListView listView = alertDialog.getListView();
listView.setAdapter(new ArrayAdapter<String>(getActivity(),
R.layout.list_item_multiple_choice_answer, items));
listView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
CheckedTextView checkedTextView = (CheckedTextView) view;
checkedItems[position] = !checkedTextView.isChecked();
}
});
listView.setDivider(null);
listView.setDividerHeight(-1);
alertDialog.setOnShowListener(new DialogInterface.OnShowListener() {
@Override
public void onShow(DialogInterface dialog) {
setCheckedItems(((AlertDialog) dialog).getListView());
}
});
alertDialog.show();
First I set the adapter with the items and the instead of calling setMultiChoiceItems I get the ListView object from the Dialog and then configure it myself.
