Question

我正在尝试创建一个AlertDialog，其中包含“下一个”和“关闭”按钮以及“不再显示”的复选框。我使用DialogFragment的支持库。以下代码工作正常，但我想使用我自己的xml布局为此AlertDialog：

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

        AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());

                builder.setTitle("ASDASDAS")
                .setPositiveButton(R.string.hello_world,
                    new DialogInterface.OnClickListener() {
                        public void onClick(DialogInterface dialog, int whichButton) {
                            ((MainActivity)getActivity()).doPositiveClick();
                        }
                    }
                )
                .setNegativeButton(R.string.cancel,
                    new DialogInterface.OnClickListener() {
                        public void onClick(DialogInterface dialog, int whichButton) {
                            ((MainActivity)getActivity()).doNegativeClick();
                        }
                    }
                );
                return builder.create();
    }

是否可以使用我自己的xml布局来创建此AlertDialog？

Answer 1

这是使用您自己的xml布局在DialogFragment中创建完全自定义AlertDialog的方法。

@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
    // Get the layout inflater
    LayoutInflater inflater = getActivity().getLayoutInflater();

    // Inflate and set the layout for the dialog
    // Pass null as the parent view because its going in the dialog layout
    builder.setView(inflater.inflate(R.layout.dialog_signin, null))
    // Add action buttons
           .setPositiveButton(R.string.signin, new DialogInterface.OnClickListener() {
               @Override
               public void onClick(DialogInterface dialog, int id) {
                   // sign in the user ...
               }
           })
           .setNegativeButton(R.string.cancel, new DialogInterface.OnClickListener() {
               public void onClick(DialogInterface dialog, int id) {
                   LoginDialogFragment.this.getDialog().cancel();
               }
           });      
    return builder.create();

使用AlertDialog.Builder#setView()

Answer 3

您可以像这样使用Dialog：

private void showIconsDlg(final int btnId) {
            // Use a custom style: IconsDialog
    final Dialog dlg = new Dialog(mContext, R.style.IconsDialog);
            // Use a custom layout: 
    dlg.setContentView(R.layout.your_custom_dlg);

    // Find and init Views
    GridView grid = (GridView) dlg.findViewById(R.id.icon_grid);


    grid.setOnItemClickListener(new OnItemClickListener() {

        @Override
        public void onItemClick(AdapterView<?> parent, View view,
                int position, long id) {
                            ...

        }
    });

    dlg.show();

}

这是主题：IconsDialog：

<style name="IconsDialog" parent="@android:style/Theme.Dialog">
    <item name="android:backgroundDimEnabled">true</item>
    <item name="android:windowBackground">@drawable/icons_dlg_bg</item>
    <item name="android:windowNoTitle">true</item>
</style>

在R.layout.your_custom_dlg。

中设置自定义提醒布局
