DialogFragment 对话框 碎片

public class ReplayRecordDialogFragment extends DialogFragment {
public static ReplayRecordDialogFragment newInstance(String file_name) {
        ReplayRecordDialogFragment dialogFragment = new ReplayRecordDialogFragment();
        Bundle bundle = new Bundle();
        bundle.putString(FILE_NAME, file_name);
        dialogFragment.setArguments(bundle);
        return dialogFragment;
    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        if (getArguments() != null) {
            file_name = getArguments().getString(FILE_NAME);
        }
    }

    @NonNull
    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        Dialog dialog = super.onCreateDialog(savedInstanceState);
        final AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
        View view = getActivity().getLayoutInflater().inflate(R.layout.fragment_replayrecord, null);

        builder.setView(view);
        return builder.create();
    }

}

使用起来与Fragment很相像

在Activity使用时：

ReplayRecordDialogFragment fragmentReplay = ReplayRecordDialogFragment.newInstance(filename_record);
fragmentReplay.show(getFragmentManager(), ReplayRecordDialogFragment.class.getSimpleName());
