先显示界面，等下载完图片再显示图片要怎么做？

Question

这个要怎么做？ 我试写了一下代码 不对。public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.jingqu_main);
new Thread() {
@Override
public void run() {
handler_zhutupian.sendEmptyMessage(1);
}
}.start();
//断点1
}// 异步回调方法_下载主图片
private Handler handler_zhutupian = new Handler() {
@Override
public void handleMessage(Message msg) {
//断点2
Toast.makeText(getApplicationContext(), "请稍等......",
Toast.LENGTH_SHORT).show();
image = (ImageView) findViewById(R.id.jingqu_main_tv_image);
String path = Global.selectJingQu.getProperty("IMAGE_PATH").toString();
if (path.equals("anyType{}"))
image.setVisibility(View.GONE);
else
image.setImageBitmap(FileHelper.getBitMap(Global.ServerImagePath
+ path));
}
};
代码会先执行断点1， 再执行断点2（下载图片）. 最后才显示界面。我需要先界面， 再下载， 最后显示界面里的图片
