听闻少年二字,当与平庸相斥。这篇文章主要讲述android 解决 多品牌手机拍照问题,尤其是小米手机相关的知识,希望能为你提供帮助。

android 解决 多品牌手机拍照问题,尤其是小米手机

文章图片

先上个图吧 .点击头像弹出下面对话框,然后直接上代码.
头像是自定义控件实现的圆形头像,当然就目前而言 想要实现 圆形头像的资料太多了,随便找个就行
< com.kuibu.jucai.widget.CircleImageView style="@style/UserFaceImageStyle" app:border_color="@color/white" app:border_width="2dip" android:id="@+id/header_img" />

对应样式:
< !-- 用户头像的样式 --> < style name="UserFaceImageStyle"> < item name="android:layout_width"> 60.0dip< /item> < item name="android:layout_height"> 60.0dip< /item> < item name="android:padding"> 1.0dip< /item> < item name="android:clickable"> true< /item> < item name="android:contentDescription"> face< /item> < item name="android:src"> @mipmap/widget_dface< /item> < item name="android:layout_alignParentRight"> true< /item> < item name="android:layout_centerVertical"> true< /item> < /style>

点击头像后的代码如下: 这里传递的是base64字符串.   当然也可以不转成base64,直接传递拍照后的 地址也是可以的.根据接口来定
另外本类需实现implementsEasyPermissions.PermissionCallbacks 该接口

private final static String FILE_SAVEPATH = Environment
.getExternalStorageDirectory().getAbsolutePath()
+ "/JuCai/Portrait/";
private Uri origUri;
private File protraitFile;
private Bitmap protraitBitmap;
private String protraitPath;
private static final int CAMERA_PERM = 1;
private String result_base64;

里面用的 selector 中的 .9图 就不发了. 一个灰色的 一个白色的. 自己在线制作一个.9图就行了. 在线制作地址如下:
