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

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{ @Overrideprotected 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);}}
