Handle programmatically erstellt Spinner und lokalisieren sie nach unten

Question

Ich entwickle App, wo Sie Ihre Schule Zeitplan (mit Auth etc.) füllen können In Dialog Klasse ich neue Spinner + TextView erstellen. Wie weisen Sie sie in MainActivity zu und wie legen Sie die Inhaltsansicht am Ende der Liste fest? Ich weiß, dass es LayoutParams gibt, aber ich kann es nicht verstehen.

Auch wäre es toll, wenn Sie mir helfen können, Elemente aus dem Dialogfenster nach der Auswahl zu entfernen.

Code:

public class OtherSubjectsDialog extends DialogFragment implements View.OnClickListener { 

public View onCreateView(LayoutInflater inflater, ViewGroup container, 
         Bundle savedInstanceState) { 
    getDialog().setTitle("Title!"); 
    View v = inflater.inflate(R.layout.dialog_layout, null); 
    v.findViewById(R.id.btn_inf).setOnClickListener(this); 
    v.findViewById(R.id.btn_phys).setOnClickListener(this); 
    v.findViewById(R.id.btn_soc).setOnClickListener(this); 
    v.findViewById(R.id.btn_chem).setOnClickListener(this); 
    v.findViewById(R.id.btn_biol).setOnClickListener(this); 
    return v; 
} 

@TargetApi(Build.VERSION_CODES.M) 
public void onClick(View v) { 
    RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT); 
    lp.alignWithParent = true; 
    Spinner spinner = new Spinner(super.getContext()); 
    ArrayAdapter<?> adapter = null; 
    TextView textView = new TextView(super.getContext()); 
    switch (v.getId()) { 
     case R.id.btn_inf: 
      adapter = ArrayAdapter.createFromResource(super.getContext(), R.array.inf_groups_array, android.R.layout.simple_spinner_item); 
      adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); 
      textView.setText("Группа по информатике:"); 
      break; 
     case R.id.btn_phys: 
      adapter = ArrayAdapter.createFromResource(super.getContext(), R.array.phys_groups_array, android.R.layout.simple_spinner_item); 
      adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); 
      textView.setText("Группа по физике:"); 
      break; 
     case R.id.btn_soc: 
      adapter = ArrayAdapter.createFromResource(super.getContext(), R.array.soc_groups_array, android.R.layout.simple_spinner_item); 
      adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); 
      textView.setText("Группа по обществознанию:"); 
      break; 
     case R.id.btn_chem: 
      adapter = ArrayAdapter.createFromResource(super.getContext(), R.array.chem_groups_array, android.R.layout.simple_spinner_item); 
      adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); 
      textView.setText("Группа по химии:"); 
      break; 
     case R.id.btn_biol: 
      adapter = ArrayAdapter.createFromResource(super.getContext(), R.array.biol_groups_array, android.R.layout.simple_spinner_item); 
      adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); 
      textView.setText("Группа по биологии:"); 
      break; 
    } 
    spinner.setAdapter(adapter); 
    super.getActivity().addContentView(textView, lp); 
    super.getActivity().addContentView(spinner, lp); 
    dismiss(); 
} 

public void onDismiss(DialogInterface dialog) { 
    super.onDismiss(dialog); 
} 

public void onCancel(DialogInterface dialog) { 
    super.onCancel(dialog); 
} 

}

Dialog XML-Fragment:

<LinearLayout 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="wrap_content" 
    android:layout_height="match_parent" 
    android:orientation="vertical"> 
    <TextView 
     android:id="@+id/textView1"

     android:layout_margin="20dp" 
     android:text="Выберите дополнительный предмет:" 
     android:textAppearance="?android:attr/textAppearanceLarge"> 
    </TextView> 

    <TableLayout 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content"> 

     <Button 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:text="@string/inf"

     <Button

      android:layout_height="wrap_content" 
      android:text="@string/chem" 
      android:id="@+id/btn_chem" /> 

     <Button 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:text="@string/biol" 
      android:id="@+id/btn_biol" /> 
    </TableLayout> 

</LinearLayout> 

Answer 1

versuchen, dies für Spinner Position:

super.getActivity().addContentView(textView, lp); 

lp.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM); 
super.getActivity().addContentView(spinner, lp);
