[英]Custom AlertDialog disappears on back button press
大家好,我創建了一個自定義提醒對話框。 在構建器中,我將cancelable設置為false,但是當我按下后退按鈕時它仍然消失了,有什么想法嗎?
這是對話框的代碼:
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();
}
這是它的顯示方式:
new HemisphereDialogFragment().show(getSupportFragmentManager(), "hemisphereDialog");
另一個小問題是,有沒有辦法更改對話框中各項的文本大小?
您將警報對話框的setCancelable(false)
設置為false,但是您的片段仍設置為cancelable,您還需要將setCancelable(false)
添加到您的片段中。
您應該在Dialog片段本身而不是AlertDialog.Builder中調用setCancellable(false)。
