java Android打开对话框

Question

我想通过点击LinearLayout（id:colorsdialogbtn）从Fragment（TrainerMenu）打开对话框（SettingsFolorDialog），但实际上一触就打开了两个对话框（相同）。我不知道怎么了，因为我只使用了一次“showEditDialog”

设置颜色对话框：

// ...

public class SettingsFColorDialod extends DialogFragment {


    public SettingsFColorDialod() {
    }

    public static SettingsFColorDialod newInstance(String title) {
        SettingsFColorDialod frag = new SettingsFColorDialod();
        Bundle args = new Bundle();
        args.putString("Choose your color", title);
        frag.setArguments(args);
        return frag;
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        return inflater.inflate(R.layout.settingsfcolordialog, container);
    }

    @Override
    public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
        super.onViewCreated(view, savedInstanceState);

        LinearLayout firstcolor = (LinearLayout) view.findViewById(R.id.FIRSTCOLOR);
        LinearLayout secondcolor = (LinearLayout) view.findViewById(R.id.SECONDCOLOR);
        prefdata = this.getActivity().getSharedPreferences("pref", Context.MODE_PRIVATE);
        editordata = prefdata.edit();

        firstcolor.setOnTouchListener(new View.OnTouchListener() {
            @Override
            public boolean onTouch(View v, MotionEvent event) {
                editordata.putString(FCOLOR_KEY,"33777F").apply();
                dismiss();
                return true;
            }
        });

        secondcolor.setOnTouchListener(new View.OnTouchListener() {
            @Override
            public boolean onTouch(View v, MotionEvent event) {
                return true;
            }
        });

        String title = getArguments().getString("Choose your color", "Choose your color");
        getDialog().setTitle(title);
        getDialog().getWindow().setSoftInputMode(
                WindowManager.LayoutParams.SOFT_INPUT_STATE_VISIBLE);
    }


}

        settingsFColorDialod.show(fm, "SettingsFColorDialog");

}

有什么不对劲吗

你需要使用setOnClickListner来监听点击，而不是setOnTouchListener，这在触摸时会被触发很多次
