ImageView+OkHttpUtils实现简单图片显示

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity" >

<ImageView
android:id="@+id/iv01"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:scaleType="fitXY"
/>

</RelativeLayout>

public class MainActivity extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final ImageView vv= (ImageView) findViewById(R.id.iv01);

OkHttpUtils.get().url("http://101.201.150.102/Public/Uploads/photo/2016-11-06/581f16830d222.jpg").build().execute(new BitmapCallback() {

@Override
public void onResponse(Bitmap bitmap, int i) {
try {
vv.setImageBitmap(bitmap);
} catch (Exception e) {
}
}

@Override
public void onError(Call arg0, Exception arg1, int arg2) {
// TODO Auto-generated method stub

}
});
}
