设置TextSpinner适配器

Question

我正在尝试为字符串数组设置TextAdapter。基本上它是一个下拉菜单，其中包含与用户想要购买的商品尺寸相关联的字符串列表。

private void SetupSpinner(String[] drawables) { 
    Spinner spinner = (Spinner) view.findViewById(R.id.spinner_sizes); 
    spinner.setAdapter(new ImageAdapter(getActivity(), R.layout.row, drawables)); 
} 

public class ImageAdapter extends ArrayAdapter<String> { 

    private String[] drawables; 

    public ImageAdapter(Context context, int textViewResourceId, String[] drawables) { 
     super(context, textViewResourceId); 

     this.drawables = drawables; 
    } 

    @Override 
    public View getDropDownView(int position, View convertView, ViewGroup parent) { 
     return getView(position, convertView, parent); 
    } 

    @Override 
    public View getView(int position, View convertView, ViewGroup parent) { 

     TextView view = new TextView(getContext()); 
     view.setText(Integer.parseInt(drawables[position])); 

     return view; 
    } 
} 

我已经使用drawables工作，但效率不高。我不想为每个尺寸选项制作图形。无论如何，所有帮助非常感谢！

Answer 1

创建一个XML custom_spinner

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

然后把微调在主XML，你需要

<Spinner 
    android:id="@+id/spinner_show" 
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:layout_marginTop="100px" 
    android:drawSelectorOnTop="true" /> 

然后在你的类

public class SpinnerCustomizationActivity extends Activity { 

String[] spinnerValues = { "Blur", "NFS", "Burnout","GTA IV", "Racing", }; 
String[] spinnerSubs = { "Ultimate Game", "Need for Speed", "Ulimate Racing", "Rockstar Games", "Thunder Bolt" }; 
@Override 
public void onCreate(Bundle savedInstanceState) {  

super.onCreate(savedInstanceState); 
setContentView(R.layout.main); 
Spinner mySpinner = (Spinner) findViewById(R.id.spinner_show);  
mySpinner.setAdapter(new MyAdapter(this, R.layout.custom_spinner, spinnerValues)); } 

public class MyAdapter extends ArrayAdapter<String> { 
public MyAdapter(Context ctx, int txtViewResourceId, String[] objects) 
{ 
    super(ctx, txtViewResourceId, objects); } 
@Override 
public View getDropDownView(int position, View cnvtView, ViewGroup prnt) { return getCustomView(position, cnvtView, prnt); } 

    @Override 
    public View getView(int pos, View cnvtView, ViewGroup prnt) 

{ 

    return getCustomView(pos, cnvtView, prnt); 
} 
    public View getCustomView(int position, View convertView, ViewGroup parent)  
    { 

LayoutInflater inflater = getLayoutInflater(); 
View mySpinner = inflater.inflate(R.layout.custom_spinner, parent, false);     
TextView main_text = (TextView)mySpinner.findViewById(R.id.text_main_seen); 
main_text.setText(spinnerValues[position]); 
TextView subSpinner = (TextView)mySpinner.findViewById(R.id.sub_text_seen); 

subSpinner.setText(spinnerSubs[position]); 
return mySpinner; } 
} 
}
