Android(安卓)相册回传 相机 （更换头像效果）
我们在开发中，经常会有用户点击头像选择相册或相机更换头像功能。
思路是首先点击头像 弹框选择 相机或者相册 选择图片 裁剪 上传。
所使用的框架MVP+Retrofit+Rxjava
废话少说 直接上代码
//绑定视图
View contentView = LayoutInflater.from(UserMessage.this).inflate(popuwindow_item, null);
View inflate = contentView.inflate(UserMessage.this, R.layout.change_user_head_pic,null);
popWnd = new PopupWindow(inflate);
popWnd.setContentView(inflate); //设置宽高 popWnd.setWidth(ViewGroup.LayoutParams.MATCH_PARENT); popWnd.setHeight(ViewGroup.LayoutParams.WRAP_CONTENT); popWnd.setFocusable(true); popWnd.setOutsideTouchable(true); popWnd.update(); popWnd.setBackgroundDrawable(new BitmapDrawable()); //获取资源id Button xiangce=inflate.findViewById(R.id.xiangce); Button xiangji=inflate.findViewById(R.id.xiangji); Button quxiao = inflate.findViewById(R.id.quxiao); //设置popuwindow位置 popWnd.showAtLocation(inflate, Gravity.BOTTOM, 0, 0);点击头像弹框popularWindow，选择相册 或者相机 亦或者取消，贴出效果图，布局就不放了。
//相册点击事件
xiangce.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
popWnd.dismiss();
//跳转相册
Intent intent1 = new Intent(Intent.ACTION_PICK, null);
intent1.setDataAndType(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, “image/*”);
Log.e("===",MediaStore.Images.Media.EXTERNAL_CONTENT_URI+""); List resolveInfos = getPackageManager().queryIntentActivities(intent1 , PackageManager.MATCH_DEFAULT_ONLY); //判断用户设备是否有相册 if (resolveInfos.size()!=0){ startActivityForResult(intent1, 1); }else{ Toast.makeText(UserMessage.this,"没有相册",Toast.LENGTH_SHORT).show(); } } }); //相机点击事件b xiangji.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { popWnd.dismiss(); //跳转向机 // Intent intent2 = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); Intent intent2 = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); intent2.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(new File(Environment.getExternalStorageDirectory(), "head.jpg"))); intent2.addCategory("android.intent.category.DEFAULT"); List resolveInfos = getPackageManager().queryIntentActivities(intent2 , PackageManager.MATCH_DEFAULT_ONLY); //判断用户设备是否有相机 if (resolveInfos.size()!=0){ startActivityForResult(intent2, 2);//采用ForResult打开 }else{ ToastUtils.setToastTextview(UserMessage.this,"没有相机"); ToastUtils.show(); // Toast.makeText(UserMessage.this,“没有相机”,Toast.LENGTH_SHORT).show();
}
} });隐式跳转跳转相机相册，此吐司为自定义吐司。
/**
* 判断是裁剪 还是 裁剪完毕
* @param requestCode
* @param resultCode
* @param data
*/
@Override
protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
switch (requestCode) {
//裁剪相册选取的图片
case 1:
if (resultCode == RESULT_OK) {
Uri data1 = data.getData();
Log.e("===",String.valueOf(data1));
cropPhoto(data.getData());//裁剪图片
}
break;
//裁剪拍照获取的图片
case 2:
if (resultCode == RESULT_OK) {
File temp = new File(Environment.getExternalStorageDirectory()
+ “/head.jpg”);
cropPhoto(Uri.fromFile(temp));//裁剪图片
}
break;
//处理图片 调用P层请求接口
case 3:
if (data != null){
Bundle extras = data.getExtras();
head = extras.getParcelable("data"); if (head != null){ headSimple.setImageBitmap(head); //BitMap转File File file = new File(Environment.getExternalStorageDirectory()+"/head.jpg"); Log.e("===",Environment.getExternalStorageDirectory()+"/head.jpg"); //将要保存图片的路径 try { BufferedOutputStream bos = new BufferedOutputStream(new FileOutputStream(file)); head.compress(Bitmap.CompressFormat.JPEG, 100, bos); bos.flush(); bos.close(); } catch (IOException e) { e.printStackTrace(); } catch (Exception e) { e.printStackTrace(); } getPresenter().UploadUserHeadPicPresenter(file); } } break; default: break; } super.onActivityResult(requestCode, resultCode, data);}/**

* @param uri
/
public void cropPhoto(Uri uri) {
Intent intent = new Intent(“com.android.camera.action.CROP”);
intent.setDataAndType(uri, "image/");
intent.putExtra(“crop”, “true”);
// aspectX aspectY 是宽高的比例
intent.putExtra(“aspectX”, 1);
intent.putExtra(“aspectY”, 1);
// outputX outputY 是裁剪图片宽高
intent.putExtra(“outputX”, 150);
intent.putExtra(“outputY”, 150);
intent.putExtra(“return-data”, true);
startActivityForResult(intent, 3);
}
对图片进行裁剪
网络请求
API
@Override
public void UploadUserHeadPicModel(File file, UploadUserHeadPicCallBackData uploadUserHeadPicCallBackData) {
RequestBody requestBody = RequestBody.create(MediaType.parse("multipart/form-data"), file); MultipartBody.Part image = MultipartBody.Part.createFormData("image", file.getName(), requestBody); httpUtils.create() .getUploadUserHeadPic(image) .subscribeOn(Schedulers.io()) .observeOn(AndroidSchedulers.mainThread()) .subscribe(new Observer() { @Override public void onSubscribe(Disposable d) { } @Override public void onNext(UploadUserHeadPicBean uploadUserHeadPicBean) { uploadUserHeadPicCallBackData.success(uploadUserHeadPicBean); } @Override public void onError(Throwable e) { } @Override public void onComplete() { } });} RequestBody requestBody = RequestBody.create(MediaType.parse(“multipart/form-data”), file);
MultipartBody.Part image = MultipartBody.Part.createFormData("image", file.getName(), requestBody);将File文件转化为MultipartBody.Part 入参
因为本人模拟器没有相机app 所以相机效果不做展示，有兴趣者可自行实现。
