Question

我正在尝试通过对话框片段进行选择。选项包括手动输入和预设输入，预设由两个按钮表示。我面临的当前问题是，当按下按钮时，我希望对话框关闭并将信息设置为目标TextView，但我一直无法找到解决方案。

当前，使用buttonfps2397，我在对话框中填充EditText，然后按OK将其发送到目标TextView，这对我来说是一击。

public class FpsDialog extends AppCompatDialogFragment{
private EditText editTextFpsEntry;
private FpsDialogListener listener;
private Button buttonfps2397;
private Button buttonfps50;

@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());

    LayoutInflater inflater = getActivity().getLayoutInflater();
    View view = inflater.inflate(R.layout.fps_dialog, null);

    builder.setView(view)
            .setTitle("Login")
            .setNegativeButton("cancel", new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialogInterface, int i) {

                }
            })
            .setPositiveButton("ok", new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialogInterface, int i) {
                    String fpsinfo = editTextFpsEntry.getText().toString();
                    listener.applyText(fpsinfo);

                }
            });


    editTextFpsEntry = view.findViewById(R.id.fpsEntry);
    buttonfps2397 = view.findViewById(R.id.fps2397);
    buttonfps50 = view.findViewById(R.id.fps50);

    buttonfps2397.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            String setFps2397 = "23,97";
            editTextFpsEntry.setText(setFps2397);



        }
    });
    buttonfps50.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            String setFps50 = "50";
            listener.applyText(setFps50);
        }
    });


    return builder.create();
}

@Override
public void onAttach(Context context) {
    super.onAttach(context);

    try {
        listener = (FpsDialogListener) context;
    } catch (ClassCastException e) {
        throw new ClassCastException(context.toString()+
                "must implement Lens Dialog Listener");
    }

}


public interface FpsDialogListener{
    void applyText(String fpsinfo);
}

<article> <h1>This is a pink page</h1> <section id="home"> Pink pink dog cat cow chicken boy </section> <section id="about"> this is a story about a pink dog named Clyde. </section> <section id="projects"> And more on the Clyde story. He has a boy. </section> </article> <button id="pink-btn">'pink'->'blue'</button> | <button id="pink-boy-btn">'pink'->'blue', 'boy'->'girl'</button> | <button id="pink-boy-dog-btn">'pink'->'blue', 'boy'->'girl', 'dog'->'cat'</button>的实例具有DialogFragment方法。您可以从按钮单击侦听器中调用此命令，以关闭对话框。
