博学谷的第五个新功能：个人资料界面点击用户头像可以通过拍照和相册选择更换头像

1、个人资料界面添加更换头像的点击事件和头像显示代码

china.ynyx.heyunhui.activity包中的UserInfoActivity.java文件中添加代码

①58行：定义私有变量

private ImageView iv_head_icon;
private static String path = "/sdcard/DemoHead/";//sd路径
private Bitmap head;//头像Bitmap
private Context context = this;
Bitmap bt = BitmapFactory.decodeFile(path + "head.jpg");//从Sd中找头像，转换成Bitmap

②78行：调动头像显示

imagehead();

③93行：头像显示代码

private void imagehead() {// TODO Auto-generated method stubif(bt!=null){iv_head_icon.setImageBitmap(bt);}else{/***  如果SD里面没有则需要从服务器取头像，取回来的头像再保存在SD中*/iv_head_icon.setImageResource(R.drawable.default_icon);}rl_head.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View v) {ActionSheetDialog();}});
}

④120行：初始化控件

iv_head_icon =(ImageView) findViewById(R.id.iv_head_icon);

⑤268行：拍照和相册选择的点击事件：

//相机拍照后的返回结果
case 3:if (resultCode == RESULT_OK) {File temp = new File(Environment.getExternalStorageDirectory()+ "/head.jpg");cropPhoto(Uri.fromFile(temp));//裁剪图片}break;//从相册里面取相片的返回结果case 4:if (resultCode == RESULT_OK) {cropPhoto(data.getData());//裁剪图片}break;
//调用系统裁剪图片后
case 5:if (data != null) {Bundle extras = data.getExtras();head = extras.getParcelable("data");if (head != null) {/*** 上传服务器代码*/setPicToView(head);//保存在SD卡中iv_head_icon.setImageBitmap(head);//用ImageView显示出来}}break;

303行：

super.onActivityResult(requestCode, resultCode, data);

⑥308行：拍照、相册、系统裁剪的具体实现代码：

 private void ActionSheetDialog() {final String[] stringItems = {"拍照", "从相册中选择", "图片商城"};final ActionSheetDialog dialog = new ActionSheetDialog(context, stringItems, null);dialog.title("请选择头像更换方式")//.titleTextSize_SP(14.5f)//.show();dialog.setOnOperItemClickL(new OnOperItemClickL() {@Overridepublic void onOperItemClick(AdapterView<?> parent, View view, int position, long id) {if (position == 0) {//调用相机拍照T.showShort(context, stringItems[position]);//最好用try/catch包裹一下，防止因为用户未给应用程序开启相机权限，而使程序崩溃try {Intent intent1 = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);//开启相机应用程序获取并返回图片（capture：俘获）intent1.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(new File(Environment.getExternalStorageDirectory(),"head.jpg")));//指明存储图片或视频的地址URIstartActivityForResult(intent1, 3);//采用ForResult打开} catch (Exception e) {Toast.makeText(UserInfoActivity.this, "相机无法启动，请先开启相机权限", Toast.LENGTH_LONG).show();}dialog.dismiss();}else if (position == 1) {//从相册里面取照片T.showShort(context, stringItems[position]);Intent intent2 = new Intent(Intent.ACTION_PICK, null);//返回被选中项的URIintent2.setDataAndType(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, "image/*");//得到所有图片的URIstartActivityForResult(intent2, 4);dialog.dismiss();}else if (position == 2) {T.showShort(context, stringItems[position]);Intent intent2 = new Intent(UserInfoActivity.this,PhotoWall.class); startActivityForResult(intent2, 0);dialog.dismiss();}}});}/*** 调用系统的裁剪** @param uri*/public void cropPhoto(Uri uri) {Intent intent = new Intent("com.android.camera.action.CROP");//找到指定URI对应的资源图片intent.setDataAndType(uri, "image/*");intent.putExtra("crop", "true");// aspectX aspectY 是裁剪框宽高的比例intent.putExtra("aspectX", 1);intent.putExtra("aspectY", 1);// outputX outputY 是裁剪图片宽高intent.putExtra("outputX", 150);// 输出图片大小intent.putExtra("outputY", 150);intent.putExtra("return-data", true);//进入系统裁剪图片的界面startActivityForResult(intent, 5);}private void setPicToView(Bitmap mBitmap) {String sdStatus = Environment.getExternalStorageState();if (!sdStatus.equals(Environment.MEDIA_MOUNTED)) { // 检测sd卡是否可用return;}FileOutputStream b = null;File file = new File(path);file.mkdirs();// 创建以此File对象为名（path）的文件夹String fileName = path + "head.jpg";//图片名字try {b = new FileOutputStream(fileName);mBitmap.compress(Bitmap.CompressFormat.JPEG, 100, b);// 把数据写入文件（compress：压缩）} catch (FileNotFoundException e) {e.printStackTrace();} finally {try {//关闭流b.flush();b.close();} catch (IOException e) {e.printStackTrace();}}}

2、“我”的界面头像显示

china.ynyx.heyunhui.view包中的MyInfoView.java文件中添加代码

①36行：定义

private static String path = "/sdcard/DemoHead/";//sd路径

②130行：设置“我”的界面头像显示，登陆成功后显示修改后的头像

Bitmap bt = BitmapFactory.decodeFile(path + "head.jpg");//从Sd中找头像，转换成Bitmap
if(bt!=null){iv_head_icon.setImageBitmap(bt);
}else{/***  如果SD里面没有则需要从服务器取头像，取回来的头像再保存在SD中*/iv_head_icon.setImageResource(R.drawable.default_icon);
}

145行：没有登录则显示默认头像

iv_head_icon.setImageResource(R.drawable.default_icon);

3、修改配置文件

在AndroidManifest.xml包中的第14行添加如下代码：

<uses-permission android:name="android.permission.CAMERA" />
<uses-feature android:name="android.hardware.camera"/>
<uses-feature android:name="android.hardware.camera.autofocus"/><uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS" />

在AndroidManifest.xml包中更换App主题：
<application中将android:theme换成

android:theme="@style/Theme.AppCompat.NoActionBar"

4、弹窗逻辑代码

在src目录下新建china.ynyx.heyunhui.dialog包，再在该包中新建更换头像时弹窗需要用到的java文件：

由于代码太多，这里就不一一展示了，需者自取：
https://yuyunyaohui.lanzoui.com/ilhz6qpnyve

添加库文件：更换头像弹窗所需要的库文件
https://yuyunyaohui.lanzoui.com/iKe6Xqpnole

5、弹窗样式

res目录下新建anim文件夹，在该文件夹中新建两个xml文件
dialog_enter.xml具体代码如下：

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" ><!-- %p指相对于父容器 --><translateandroid:duration="500"android:fromYDelta="-100%p" />
</set>

dialog_exit.xml具体代码如下：

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" ><translateandroid:duration="500"android:toYDelta="-100%p" />
</set>

res目录下的layout文件夹中新建ac_dialog_home.xml文件

<?xml version="1.0" encoding="utf-8"?>
<ExpandableListView xmlns:android="http://schemas.android.com/apk/res/android"android:id="@+id/elv"android:background="#ffffff"android:layout_width="fill_parent"android:layout_height="fill_parent"android:cacheColorHint="#00000000"android:divider="@null"android:fadingEdge="none"android:groupIndicator="@null"android:listSelector="#00000000"android:scrollbars="none" />

res目录下的values文件夹中的styles.xml中20行添加代码：

<style name="myDialogAnim" parent="android:Animation"><!-- 进入时的动画 --><item name="@android:windowEnterAnimation">@anim/dialog_enter</item><!-- 退出时的动画 --><item name="@android:windowExitAnimation">@anim/dialog_exit</item>
</style>
