Android带头像的用户注册页面

详细的图文可以到我的百度经验去查看：http://jingyan.baidu.com/article/cd4c2979eda109756e6e60de.html

首先是注册页面的布局：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117

<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"     android:layout_width="fill_parent"     android:layout_height="fill_parent"     android:paddingTop="20px"     android:orientation="horizontal" >       <LinearLayout         android:id="@+id/linearLayout1"         android:orientation="vertical"         android:layout_weight="2"         android:paddingLeft="20px"         android:layout_width="wrap_content"         android:layout_height="wrap_content" >           <TableLayout             android:id="@+id/tableLayout1"             android:layout_width="match_parent"             android:layout_height="wrap_content" >               <TableRow                 android:id="@+id/tableRow1"                 android:layout_width="wrap_content"                 android:layout_height="wrap_content" >                 <TextView                     android:id="@+id/textView1"                     android:textSize="20px"                     android:layout_width="wrap_content"                     android:layout_height="wrap_content"                     android:text="用户名：" />                   <EditText                     android:id="@+id/user"                     android:minWidth="400px"                     android:layout_width="wrap_content"                     android:layout_height="wrap_content" />               </TableRow>               <TableRow                 android:id="@+id/tableRow2"                 android:layout_width="wrap_content"                 android:layout_height="wrap_content" >                 <TextView                     android:id="@+id/textView2"                     android:textSize="20px"                     android:layout_width="wrap_content"                     android:layout_height="wrap_content"                     android:text="密码：" />                   <EditText                     android:id="@+id/pwd"                     android:inputType="textPassword"                     android:layout_width="wrap_content"                     android:layout_height="wrap_content" />             </TableRow>               <TableRow                 android:id="@+id/tableRow3"                 android:layout_width="wrap_content"                 android:layout_height="wrap_content" >                 <TextView                     android:id="@+id/textView3"                     android:textSize="20px"                     android:layout_width="wrap_content"                     android:layout_height="wrap_content"                     android:text="确认密码：" />                   <EditText                     android:id="@+id/repwd"                     android:inputType="textPassword"                     android:layout_width="wrap_content"                     android:layout_height="wrap_content" />             </TableRow>               <TableRow                 android:id="@+id/tableRow4"                 android:layout_width="wrap_content"                 android:layout_height="wrap_content" >                 <TextView                     android:id="@+id/textView4"                     android:textSize="20px"                     android:layout_width="wrap_content"                     android:layout_height="wrap_content"                     android:text="E-mail地址：" />                   <EditText                     android:id="@+id/email"                     android:layout_width="wrap_content"                     android:layout_height="wrap_content" />             </TableRow>         </TableLayout>       </LinearLayout>     <LinearLayout         android:id="@+id/linearLayout2"         android:orientation="vertical"         android:gravity="center_horizontal"         android:layout_width="wrap_content"         android:layout_weight="1"         android:layout_height="wrap_content" >           <ImageView             android:id="@+id/imageView1"             android:layout_width="158px"             android:layout_height="150px"             android:src="@drawable/ic_launcher" />           <Button             android:id="@+id/button1"             android:layout_width="wrap_content"             android:layout_height="wrap_content"             android:text="选择头像" />       </LinearLayout>   </LinearLayout>

然后是图库的页面布局，由用户去选择图片，这里我就用windows系统里面的几张照片

<?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">

 

    <GridView

        android:layout_width="wrap_content"

        android:layout_height="match_parent"

        android:id="@+id/gridView"

        android:numColumns="4" />

</LinearLayout>

然后我们在注册页面的Activity写入以下代码：

Button button1=(Button)findViewById(R.id.button1);
        button1.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent intent = new Intent(MainActivity.this,HeadActivity.class);
                startActivityForResult(intent,0x11);
            }
        });

@Override onActivityResult方法：
    protected void onActivityResult(int requestCode,int resultCode,Intent data){
        super.onActivityResult(requestCode,resultCode,data);
        if(requestCode==0x11&&requestCode==0x11){
            Bundle bundle=data.getExtras();
            int imageId=bundle.getInt("imageId");
            ImageView imageView=(ImageView)findViewById(R.id.imageView1);
            imageView.setImageResource(imageId);
        }
    }

点击按钮跳转到图库Activity页面中。

在图库Activity里面写入以下代码响应用户点击图片并通过Intent传递给前一个Activity：

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42

GridView gridView=(GridView)findViewById(R.id.gridView);         BaseAdapter adapter=new BaseAdapter() {             @Override             public int getCount() {                 return imageId.length;             }             @Override             public Object getItem(int position) {                 return position;             }             @Override             public long getItemId(int position) {                 return position;             }             @Override             public View getView(int position, View convertView, ViewGroup parent) {                 ImageView imageView;                 if(convertView==null){                     imageView=new ImageView(HeadActivity.this);                     imageView.setAdjustViewBounds(true);                     imageView.setMaxHeight(58);                     imageView.setMaxWidth(50);                     imageView.setPadding(5,5,5,5);                 }else{                     imageView=(ImageView)convertView;                 }                 imageView.setImageResource(imageId[position]);                 return imageView;             }         };         gridView.setAdapter(adapter);         gridView.setOnItemClickListener(new AdapterView.OnItemClickListener() {             @Override             public void onItemClick(AdapterView<?> parent, View view, int position, long id) {                 Intent intent=getIntent();                 Bundle bundle=new Bundle();                 bundle.putInt("imageId",imageId[position]);                 intent.putExtras(bundle);                 setResult(0x11,intent);                 finish();             }         });

结果如下：
