在对话框中使用多个按钮,意图更改主按钮的文本
目前,我在一个腌制中如何在一个对话框中进行3个按钮,使选项选择“选定”的选项更改用于显示对话框的按钮的文本,到目前为止,我只是设法使Option3工作3最后一个意图,因此唯一有效的按钮是选项3的按钮3,
这是IM试图从对话框中传递到主按钮的代码
public class LabelDialog extends AppCompatDialogFragment {
private Button option1, option2, option3;
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
LayoutInflater inflater = getActivity().getLayoutInflater();
View view = inflater.inflate(R.layout.label_dialog, null);
builder.setView(view);
//option 1 and 2
option3 = view.findViewById(R.id.label_lecturebtn);
option3.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
String option3 = "Lecture";
Intent intent3 = new Intent(getContext(), AddTask.class);
intent3.putExtra("lecture", option3);
startActivity(intent3);
dismiss();
}
});
,而主体代码
protected void onCreate(Bundle savedInstanceState) {
//...
label_button = findViewById(R.id.button_labels);
label_button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
openDialog();
}
});
checkLabelResult();
}
public void openDialog() { //Labels dialog
//code to open dialog
}
public void checkLabelResult() {
//intents 1 and 2, same format as 3 but keys changed accordingly
Intent intent3 = getIntent();
String option3 = intent3.getStringExtra("lecture");
label_button.setText(option3);
}
是
option1.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
String option1 = "Important";
Intent intent = new Intent(getContext(), AddTask.class);
intent.putExtra("important", option1);
startActivity(intent);
dismiss();
}
选项2的选项1代码
option2.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
String option2 = "To Do";
Intent intent2 = new Intent(getContext(), AddTask.class);
intent2.putExtra("to do", option2);
startActivity(intent2);
dismiss();
}
i am in a pickle at the moment to how to approach making 3 buttons within a single dialog box make the option selected change the text of the button used to show the dialog box, so far only managed to get option3 to work as i suppose its the last intent so the only button that works would be the button for option3
here is the code im trying to pass to the main button from the dialog
public class LabelDialog extends AppCompatDialogFragment {
private Button option1, option2, option3;
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
LayoutInflater inflater = getActivity().getLayoutInflater();
View view = inflater.inflate(R.layout.label_dialog, null);
builder.setView(view);
//option 1 and 2
option3 = view.findViewById(R.id.label_lecturebtn);
option3.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
String option3 = "Lecture";
Intent intent3 = new Intent(getContext(), AddTask.class);
intent3.putExtra("lecture", option3);
startActivity(intent3);
dismiss();
}
});
and the main code
protected void onCreate(Bundle savedInstanceState) {
//...
label_button = findViewById(R.id.button_labels);
label_button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
openDialog();
}
});
checkLabelResult();
}
public void openDialog() { //Labels dialog
//code to open dialog
}
public void checkLabelResult() {
//intents 1 and 2, same format as 3 but keys changed accordingly
Intent intent3 = getIntent();
String option3 = intent3.getStringExtra("lecture");
label_button.setText(option3);
}
Code for Option 1
option1.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
String option1 = "Important";
Intent intent = new Intent(getContext(), AddTask.class);
intent.putExtra("important", option1);
startActivity(intent);
dismiss();
}
Code for Option 2
option2.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
String option2 = "To Do";
Intent intent2 = new Intent(getContext(), AddTask.class);
intent2.putExtra("to do", option2);
startActivity(intent2);
dismiss();
}
