arrayAdapter list 圖片

arrayAdapter list 圖片 關鍵字: android1. ArrayAdapter (Context context, int resource, int textViewResourceId, T[] objects) 
2.ArrayAdapter (Context context, int textViewResourceId, T[] objects) 
3. ArrayAdapter (Context context, int resource, int textViewResourceId, T[] objects) 
幾種常用的解釋： 
1.resource 一般為 layout ,T[] objects為數組，textViewResourceId 一般為textview即要顯示 objects中的每一項（比如如下） 
  <?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:layout_width="fill_parent" 
android:layout_height="wrap_content" 
android:orientation="horizontal" 
> 
<ImageView 
android:id="@+id/icon" 
android:layout_width="22px" 
android:paddingLeft="2px" 
android:paddingRight="2px" 
android:paddingTop="2px" 
android:layout_height="wrap_content" 
android:src="@drawable/ok" 
/> 
<TextView 
android:id="@+id/label" 
android:layout_width="wrap_content" 
android:layout_height="wrap_content" 
android:textSize="44sp" 
/> 
</LinearLayout> 

setListAdapter(new ArrayAdapter<String>(this, 
R.layout.row, R.id.label,items)); 
這樣就可以實現圖片和文字在list 中。 
當然你也可以用 
tv_show.setCompoundDrawablesWithIntrinsicBounds();實現該例子 
如果你要動態建立list圖案的話，那麼最後的做法就是自己寫一個類繼承baseAdapter 

public class DynamicDemo extends ListActivity { 
TextView selection; 
String[] items={"lorem", "ipsum", "dolor", "sit", "amet", 
"consectetuer", "adipiscing", "elit", "morbi", "vel", 
"ligula", "vitae", "arcu", "aliquet", "mollis", 
"etiam", "vel", "erat", "placerat", "ante", 
"porttitor", "sodales", "pellentesque", "augue", 
"purus"}; 
@Override 
public void onCreate(Bundle icicle) { 
super.onCreate(icicle); 
setContentView(R.layout.main); 
setListAdapter(new IconicAdapter(this)); 
selection=(TextView)findViewById(R.id.selection); 
} 
public void onListItemClick(ListView parent, View v, 
int position, long id) { 
selection.setText(items[position]); 
} 
class IconicAdapter extends ArrayAdapter { 
Activity context; 
IconicAdapter(Activity context) { 
super(context, R.layout.row, items); 
this.context=context; 
} 
public View getView(int position, View convertView, 
ViewGroup parent) { 
ViewInflate inflater=context.getViewInflate(); 
View row=inflater.inflate(R.layout.row, null, null); 
TextView label=(TextView)row.findViewById(R.id.label); 
label.setText(items[position]); 
if (items[position].length()>4) { 
ImageView icon=(ImageView)row.findViewById(R.id.icon); 
icon.setImageResource(R.drawable.delete); 
} 
return(row); 
} 
} 
}
