Question

大家好我有一个我创建的自定义警报对话框。在构建器中我将cancelable设置为false但是当我按下后退按钮时它仍然消失了吗？

这是对话框的代码：

public final class HemisphereDialogFragment extends DialogFragment {
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    // Use the Builder class for convenient dialog construction
    AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
    LayoutInflater inflater = getActivity().getLayoutInflater();
    View customTitle = inflater.inflate(R.layout.hemisphere_dialog_custom_title, null);
    builder.setCustomTitle(customTitle);
    String[] entries = new String[2];
    entries[0] = getResources().getString(R.string.northern_hemisphere);
    entries[1] = getResources().getString(R.string.southern_hemisphere);
    builder.setItems(entries, new DialogInterface.OnClickListener() {
        //The 'which' argument contains the index position of the selected item
        public void onClick(DialogInterface dialog, int which) {
            if( which == 0 ) {
                GlobalVariables.getShared().setIsInNorthernHemisphere(true);
            } else if( which == 1 ) {
                GlobalVariables.getShared().setIsInNorthernHemisphere(false);
            }

            ToolbarActivity.outfitsFragment.hemisphereSelected();
            GlobalVariables.getShared().setHasAskedForHemisphere(true);
        }
    });
    builder.setCancelable(false);

    //Create the AlertDialog object and return it
    return builder.create();
}

这就是它的显示方式：

new HemisphereDialogFragment().show(getSupportFragmentManager(), "hemisphereDialog");

另一个小问题，是否有办法更改对话框中项目的文字大小？

Answer 1

您将警报对话框设置为false，但您的片段仍设置为可取消，您还需要将<?php $str = "cricket, foot ball, hockey, basket ball"; $games = (explode(",",$str)); for($i=0; $i<count($games); $i++){ $game = trim($games[$i]," "); $game = str_replace(' ', '-', $game); echo '<a href="/game.php='.$game.'">'.$games[$i].'</a><br>'; } ?>添加到您的片段中。

Answer 2

你应该在Dialog片段本身而不是AlertDialog.Builder中调用setCancellable（false）。

按下后退按钮时，Custom AlertDialog消失
