android 中怎么把一张图片画到textview上

Answer 1

实现ImageGetter接口，异步加载图片。
class HtmlImageGetter extends ImageGetter{
private TextView tv;
private Drawable drawable;

public HtmlImageGetter(TextView tv,Drawable drawable){
this.tv = tv;
this.drawable = drawable;

}

@Override
public Drawable loadImage(String resoure){
//最好使用缓存，缓存一下图片文件

ImageAsyncLoader loader = new ImageAsyncLoad();
loader.execute(resource);
return this.drawable;

}
class ImageAsyncLoader extends AsyncTask<String,Void,Drawable>{
@Override
puclic Drawable doInBackground(String... params){
try{

NetUtils.getImage(params[0]);
}...................

}
@Override
public void postExecute(Drawable result){
//解析图片并作TextView刷新

}

}

}

Answer 2

TextView有一个属性叫做android:drawableTop。
