Android 加载图片传到另一个页面 关于回调

这里用到一个包 xutilslibrary.jar

直接上代码：

acricity_mai1.xml

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

    <ImageView 
        android:id="@+id/img"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        />
    
</LinearLayout>

activity_main.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/LinearLayout1"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context=".MainActivity" >

    <ImageView
        android:id="@+id/image"
        android:layout_width="match_parent"
        android:layout_height="150dp" />

    <Button
        android:id="@+id/button"
        android:layout_width="100dp"
        android:layout_height="40dp" 
        android:background="#1eb2ff"
        android:layout_gravity="center_horizontal"
        android:text="add_img"
        android:textColor="#ffffff"
        android:gravity="center"/>
    
    <Button 
        android:id="@+id/fashe"
        android:layout_width="100dp"
        android:layout_height="40dp"
        android:background="#1eb2ff"
        android:textColor="#ffffff"
        android:text="发射"
        android:layout_gravity="center_horizontal"
        android:gravity="center"
        android:layout_marginTop="10dp"/>

</LinearLayout>

MainActivity

package com.example.test1;

	}
	
	@Override

	}
}

MainActivity1

package com.example.test1;

import com.lidroid.xutils.BitmapUtils;

import android.app.Activity;
import android.os.Bundle;
import android.widget.ImageView;

public class MainActivity1 extends Activity{
	 @Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.acricity_mai1);
		ImageView img=(ImageView) findViewById(R.id.img);
		String ui=getIntent().getStringExtra("bian");
		BitmapUtils bitmapUtils=new BitmapUtils(MainActivity1.this);
		bitmapUtils.display(img, ui);

	}
}
