自定义对话框与setMultiChoiceItems [英] Custom Dialog with setMultiChoiceItems

问题描述

我想创建一个方式，用户可以选择像下面

I want to create a way users can select options like the image below

现在我在做以下

public static class CategoriesDialogFragment extends SherlockDialogFragment {

    public static CategoriesDialogFragment newInstance(int title) {
        CategoriesDialogFragment frag = new CategoriesDialogFragment();
        Bundle args = new Bundle();
        args.putInt("title", title);
        frag.setArguments(args);
        return frag;
    }

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        int title = getArguments().getInt("title");

        return new AlertDialog.Builder(getActivity())
                .setIcon(R.drawable.alert_dialog_icon)
                .setTitle(title)
                .setMultiChoiceItems(_categories, _selections,
                        new DialogSelectionClickHandler())
                .setPositiveButton(R.string.alert_dialog_ok,
                        new DialogInterface.OnClickListener() {
                            public void onClick(DialogInterface dialog,
                                    int whichButton) {
                                ((MainActivity) getActivity())
                                        .doPositiveClick();
                            }
                        }).create();

        /*
         * .setNegativeButton(R.string.alert_dialog_cancel, new
         * DialogInterface.OnClickListener() { public void
         * onClick(DialogInterface dialog, int whichButton) {
         * ((MainActivity) getActivity()) .doNegativeClick(); } })
         */
    }

    public class DialogSelectionClickHandler implements
            DialogInterface.OnMultiChoiceClickListener {
        public void onClick(DialogInterface dialog, int clicked,
                boolean selected) {
            // Log.i("ME", _options[clicked] + " selected: " + selected);
        }
    }

}

不过，我想补充，如图像中的所有选项。所以，我想我将不得不建立一个自定义对话框。我仍然可以扩展本机setMultiChoiceItems，这样它会降低我的code处理。

But i want to add ALL option like the image. So i think i will have to build a custom Dialog. Can i still extend the native setMultiChoiceItems so that it will reduce my handling of the code.

推荐答案

您也许可以使用<一个href="http://developer.android.com/reference/android/app/AlertDialog.Builder.html#setCustomTitle%28android.view.View%29"><$c$c>setCustomTitle()在 AlertDialog.Builder 类的方法和构造自己的头衔有标题的文本，也是的所有的复选框，是这样的：

You could probably use the setCustomTitle() method of the AlertDialog.Builder class and construct your own title which has the title text and also the all CheckBox, something like this:

new AlertDialog.Builder(getActivity())
                .setIcon(R.drawable.alert_dialog_icon)
                .setTitle(title)
                .setCustomTitle(getLayoutInflater().inflate(R.layout.custom_title, null));

其中， R.layout.custom_title 是：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >

    <TextView
        android:id="@+id/textView1"
        style="?android:attr/textAppearanceLarge"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:text="Dialog title"
        android:textColor="#ffffff" />

    <TextView
        android:id="@+id/all"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="All"
        android:textColor="#ffffff" />

    <CheckBox
        android:id="@+id/checkBox1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

</LinearLayout>

其他风格的调整应以使其​​更好看。 但看到整个对话框的布局，你可能想要去与一个自定义的对话框类，其中 setMultiChoice（）方法将不可用（但最终它会很容易复制）。

Other style tweaks should be made to make it look better. But seeing the entire dialog layout you may want to go with a custom Dialog class, for which the setMultiChoice() method will not be available(but in the end it will be easy to replicate).
