我有一个正在返回的字符串,它是xml布局文件中出现的图像的位置,因此“@ drawable / image”。
我的问题是可以在代码中更改android:src =“@ drawable / image”中的字符串吗?
编辑:
<ImageView
android:id="@+id/imageuni"
android:layout_width="50dip"
android:layout_height="50dip"
android:src="@drawable/no_image"/> <!--Change this part in code-->
我正在使用带有CustomBinder的SimpleAdapter:
SimpleAdapter adapter = new SimpleAdapter( SearchActivity.this,leaderList, R.layout.search_entry, new String[] {
"rankId","name","location","image"}, new int[] {R.id.rankId,R.id.name,R.id.location,R.id.imageuni});
adapter.setViewBinder(new CustomViewBinder());
setListAdapter(adapter);
活页夹代码:
class CustomViewBinder implements SimpleAdapter.ViewBinder {
public boolean setViewValue(View view, Object inputData, String textRepresentation) {
int id = view.getId();
String data = (String) inputData;
switch (id) {
case R.id.imageuni:
populateImage(view, data);
break;
case R.id.location:
populateLocation(view, data);
break;
case R.id.name:
populateName(view, data);
break;
}
return true;
}
public void populateImage(View view, String imageData) {
ImageView uniImage = (ImageView) view.findViewById(R.id.imageuni);
uniImage.setImageDrawable(Drawable.createFromPath(imageData));
}
public void populateLocation(View view, String data) {
TextView locationTxt = (TextView) view.findViewById(R.id.location);
locationTxt.setText(data);
}
public void populateName(View view, String data) {
TextView dateTxt = (TextView) view.findViewById(R.id.name);
dateTxt.setText(data);
}
}
我获取行项的ID并构建一个字符串以获取图像的名称,例如第一个图像名为u1.jpg,它位于我的drawable res文件夹中。
答案 0 :(得分:0)
你在找这个吗?
ImageView img = (ImageView) findViewById(R.id.img);
img.setImageResource(R.drawable.u1);
