核心文件

package com.examp.use_android_smart_image_view;

import com.loopj.android.image.SmartImageView;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.EditText;

public class MainActivity extends Activity {
private EditText et_path;
private SmartImageView siv;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
et_path = (EditText) findViewById(R.id.et_path);
et_path.setText("http://c.hiphotos.baidu.com/image/w%3D310/sign=1ebfb751a6c27d1ea5263dc52bd4adaf/78310a55b319ebc47dc5736c8026cffc1f171681.jpg");

}

public void checkImage(View view) {
siv = (SmartImageView) findViewById(R.id.siv);

// 加载的路径|如果没有加载到显示的内容|等待加载的图片
siv.setImageUrl(et_path.getText().toString().trim(),
R.drawable.ic_launcher, R.drawable.ic_launcher);
}

}

注:使用前提,需要加入Android-smart-image-view框架
