在学郭霖大神的第一行代码的时候,学到利用相机拍照和从本地相册取照片的那一小节的时候,代码写出来但是出了很多问题,APP老是崩溃,一番百度最终还是没有找到解决办法
无奈只能用别人现成的*了,然后就发现了这个TakePhoto框架,很多人都推荐用这个,所以写下这个博客来记录一下这个框架的基本使用
TakePhoto是一个很优秀的关于图片的一些处理的第三方框架
GitHub地址如下:https://github.com/crazycodeboy/TakePhoto
配置的办法很简单,在工程目录的APP目录下的build.gradle里面的dependencies标签加入依赖即可
compile 'com.jph.takephoto:takephoto_library:4.0.3'
官方的最新版本是4.1.0,但我这边加入4.1.0的依赖会报错,然后我试了一下4.0.3的是可以的,所以就直接用4.0.3了
大致实现过程就是实现TakePhoto.TakeResultListener, InvokeListener接口
然后重写几个方法就行,方法体里面的内容根据自己的项目需要进行编写

PermissionManager.TPermissionType type = PermissionManager.checkPermission(TContextWrap.of(this), invokeParam.getMethod());
if (PermissionManager.TPermissionType.WAIT.equals(type)) {
this.invokeParam = invokeParam;
}
return type;
} public TakePhoto getTakePhoto() {
//获得TakePhoto实例
if (takePhoto == null) {
takePhoto = (TakePhoto) TakePhotoInvocationHandler.of(this).bind(new TakePhotoImpl(this, this));
}
//设置压缩规则，最大500kb
takePhoto.onEnableCompress(new CompressConfig.Builder().setMaxSize(500 * 1024).create(), true);
return takePhoto;
} @Override
public void takeSuccess(final TResult result) {
//成功取得照片
test = new File(result.getImage().getOriginalPath());
editor = sharedPreferences.edit();
editor.putString("image_path",result.getImage().getOriginalPath());
editor.commit();
if(test.exists()){
bitmap = BitmapFactory.decodeFile(result.getImage().getOriginalPath());
headSculpture.setImageBitmap(bitmap);
}
} @Override
public void takeFail(TResult result, String msg) {
//取得失败
Toast.makeText(Setting.this,"设置失败",Toast.LENGTH_SHORT).show();
} @Override
public void takeCancel() {
//取消
} }
取出照片还有一些其他操作可能需要看一下里面TResult和TImage这两个类
效果如下
