Android網絡圖片查看器Ⅱ （使用smart image view）

1、首先加入smart image view 控件，通常直接粘貼源碼比較好

佈局：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/widget32"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <com.loopj.android.image.SmartImageView
        android:id="@+id/siv"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1000" />

    <EditText
        android:id="@+id/et"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:gravity="center"
        android:hint="請輸入地址"
        android:text="http://i7.hexunimg.cn/2013-03-29/152620496.jpg"
        android:textSize="18sp" />

    <Button
        android:id="@+id/btn"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:onClick="click"
        android:text="獲取並瀏覽" />

</LinearLayout>

2、主activity

package com.pas.imageviewpro;

import com.loopj.android.image.SmartImageView;

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

public class MainActivity extends Activity
{

	private EditText et_path;
	@Override
	protected void onCreate(Bundle savedInstanceState)
	{
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		et_path=(EditText)findViewById(R.id.et);
	}

	@Override
	public boolean onCreateOptionsMenu(Menu menu)
	{
		// Inflate the menu; this adds items to the action bar if it is present.
		getMenuInflater().inflate(R.menu.main, menu);
		return true;
	}

	public void click(View view)
	{
		SmartImageView siv=(SmartImageView)findViewById(R.id.siv);
		String url=et_path.getText().toString().trim();
		siv.setImageUrl(url,R.drawable.ic_launcher,R.drawable.ic_launcher);
	}
}
