我有设置类。我在里面使用首选项。在首选项中,我使用其中包含AlertDialog
和EditText
的radioButton
。我想从我的设置活动中获取编辑文本和单选按钮的值,但是我在网上看到的所有内容仅与首选项OR AlertDialog
有关,并且如果将它们组合在一起,我不知道该怎么办。
我的Settings.java:
public class Settings extends AppCompatActivity {
private RadioGroup radioGroup;
AlertDialog.Builder builder;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.settings_activity);
getSupportFragmentManager()
.beginTransaction()
.replace(R.id.fragment_setting, new MySettingsFragment())
.commit();
}
public static class MySettingsFragment extends PreferenceFragmentCompat {
@Override
public void onCreatePreferences(Bundle savedInstanceState, String rootKey) {
setPreferencesFromResource(R.xml.preference, rootKey);
}
@Override
public boolean onPreferenceTreeClick(Preference p){
final EditText input = new EditText(this.getContext());
if(p.getKey().equals("appointment type")){
return true;
}
if(p.getKey().equals("time frame")){
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
LayoutInflater inflater = requireActivity().getLayoutInflater();
builder.setView(inflater.inflate(R.layout.set_time, null)).
setPositiveButton(R.string.save_settings, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
**Here i dont know how to take the value**
}
})
.setNegativeButton(R.string.cancel_settings, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
dialog.cancel();
}
});
AlertDialog dialog = builder.create();
dialog.show();
}
我的Prefernce.xml:
<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen
xmlns:android="http://schemas.android.com/apk/res/android">
<EditTextPreference
android:key="appointment type"
android:title="Set appointment types"

<Preference
android:id="@+id/remindTime"
android:key="remind time"
android:title="Meetings reminder"
android:summary="How much time to remind client before a meeting"
android:icon="@drawable/send_reminder" />
</PreferenceScreen>
我的setTime.xml(对话框):
