创建"Global"警报对话框

Question

嘿，伙计们，我正试图创建一个包含用户文本输入的AlertDialog因为在我的应用程序中，我至少需要其中的3个，我认为创建一个AlertDialog方法来返回用户在其中键入的值是个好主意转换为一种特定的方法，并通过这种方式节省编写大量代码的

这是我的代码样本

public void alrtDialog(String setTitle, String setPositiveBtn)
{
    AlertDialog.Builder myDialog = new AlertDialog.Builder(context);//<--create alert dialog builder
    myDialog.setTitle(setTitle);
    final EditText myText = new EditText(context);
    myText.setInputType(InputType.TYPE_CLASS_TEXT);
    myDialog.setView(myText);
    Log.e("blalba", "texoutt:" + myText.getText().toString());
    myDialog.setPositiveButton(setPositiveBtn, new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
            setMsg(myText.getText().toString());//<--set
            Log.e("blalba", "teinxt:" + myText.getText().toString());
        }
    });
    myDialog.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
            dialog.cancel();
        }
    });
    myDialog.show();
    return getMsg();
}

创建对话框片段

public class MyDialogFragment extends DialogFragment {
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View rootView = inflater.inflate(R.layout.fragment_sample_dialog, container, false);
        getDialog().setTitle("Simple Dialog");
        return rootView;
    }
}

在任何上下文中显示

FragmentManager fm = getFragmentManager();
MyDialogFragment dialogFragment = new MyDialogFragment ();
dialogFragment.show(fm, "Sample Fragment");
