implementation 'com.github.bumptech.glide:glide:3.7.0' //用来加载图片implementation 'pub.devrel:easypermissions:1.3.0' 还要记得在清单文件中加入 以下代码
在activity 的oncreate 中加入
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) { StrictMode.VmPolicy.Builder builder = new StrictMode.VmPolicy.Builder(); StrictMode.setVmPolicy(builder.build());}
主要代码 layout 就是一个触发事件的 Onclick
private String[] permissions = {Manifest.permission.CAMERA, Manifest.permission.WRITE_EXTERNAL_STORAGE}; getPermission();//获取权限
getCameraDialog();//相机和相册
//---------------------------//获取权限 private void getPermission() { if (EasyPermissions.hasPermissions(this, permissions)) { //已经打开权限// Toast.makeText(this, "已经申请相关权限", Toast.LENGTH_SHORT).show(); } else { //没有打开相关权限、申请权限 EasyPermissions.requestPermissions(this, "需要获取您的相册、照相使用权限", 1, permissions); } }
/** * 调取用户选择 相册 相机的弹窗 */private void getCameraDialog() { AlertDialog builder = new AlertDialog.Builder(SalesAdvanceOrderActivity.this) .setTitle("选择头像") .setPositiveButton("相机", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { selectCamera(); } }) .setNegativeButton("相册", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { selectPhoto(); } }) .show();}
private static final int GET_BACKGROUND_FROM_CAPTURE_RESOULT = 1;private static final int RESULT_REQUEST_CODE = 2;private static final int TAKE_PHOTO = 3;private Uri photoUri; //相机拍照返回图片路径private File outputImage;//选择相机private void selectCamera() { //创建file对象，用于存储拍照后的图片，这也是拍照成功后的照片路径 outputImage = new File(this.getExternalCacheDir(), "camera_photos.jpg"); try { //判断文件是否存在，存在删除，不存在创建 if (outputImage.exists()) { outputImage.delete(); } outputImage.createNewFile(); } catch (IOException e) { e.printStackTrace(); } photoUri = Uri.fromFile(outputImage); Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); intent.putExtra(MediaStore.EXTRA_OUTPUT, photoUri); startActivityForResult(intent, TAKE_PHOTO);}
public static final String STR_IMAGE = "image/*";//选择相册private void selectPhoto(){ Intent intent = new Intent(Intent.ACTION_PICK, null); intent.setDataAndType(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, STR_IMAGE); startActivityForResult(intent, GET_BACKGROUND_FROM_CAPTURE_RESOULT);} 相册和 拍照都已经vc 完毕 接下来就是 回调了
@Overrideprotected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) { if (resultCode != RESULT_OK) return; switch (requestCode) { case GET_BACKGROUND_FROM_CAPTURE_RESOULT: //相册返回 photoUri = data.getData(); cropRawPhoto(photoUri); break; case TAKE_PHOTO:// 拍照返回 cropRawPhoto(photoUri); break; case RESULT_REQUEST_CODE: //裁剪完照片 if (cropImgUri != null) { try { Bitmap headImage = BitmapFactory.decodeStream(this.getContentResolver().openInputStream(cropImgUri)); mSalesAddImg.setImageBitmap(headImage); File file = getFile(headImage);//把Bitmap转成File //上传图片 OkHttpClient httpClient = new OkHttpClient(); MediaType mediaType = MediaType.parse("application/octet-stream");//设置类型，类型为八位字节流 RequestBody requestBody = RequestBody.create(mediaType, file);//把文件与类型放入请求体 MultipartBody multipartBody = new MultipartBody.Builder() .setType(MultipartBody.FORM) .addFormDataPart("image", file.getName(), requestBody)//文件名,请求体里的文件 .build(); Request request = new Request.Builder() .url(UpUser_Img) .post(multipartBody) .build(); Call call = httpClient.newCall(request); call.enqueue(new Callback() { @Override public void onFailure(Call call, IOException e) { } @Override public void onResponse(Call call, Response response) throws IOException { String string = response.body().string(); ImgBean imgBean = new Gson().fromJson(string, ImgBean.class); if(imgBean.getStatus()==1){ ImageUrl=imgBean.getThumb(); } } }); } catch (Exception e) { e.printStackTrace(); } } else { Toast.makeText(this, "cropImgUri为空！", Toast.LENGTH_SHORT).show(); } break; } super.onActivityResult(requestCode, resultCode, data);} 还有裁切的 方法
private Uri cropImgUri; //裁剪图片 public void cropRawPhoto(Uri uri) { //创建file文件，用于存储剪裁后的照片 cropImage = new File(Environment.getExternalStorageDirectory(), "crop_image.jpg"); String path = cropImage.getAbsolutePath(); try { if (cropImage.exists()) { cropImage.delete(); } cropImage.createNewFile(); } catch (IOException e) { e.printStackTrace(); } cropImgUri = Uri.fromFile(cropImage); Intent intent = new Intent("com.android.camera.action.CROP");//设置源地址uri intent.setDataAndType(photoUri, "image/*"); intent.putExtra("crop", "true"); intent.putExtra("aspectX", 1); intent.putExtra("aspectY", 1); intent.putExtra("outputX", 200); intent.putExtra("outputY", 200); intent.putExtra("scale", true);//设置目的地址uri intent.putExtra(MediaStore.EXTRA_OUTPUT, cropImgUri);//设置图片格式 intent.putExtra("outputFormat", Bitmap.CompressFormat.JPEG.toString()); intent.putExtra("return-data", false); intent.putExtra("noFaceDetection", true); // no face detection startActivityForResult(intent, RESULT_REQUEST_CODE); }
//把bitmap转成filepublic File getFile(Bitmap bitmap) { ByteArrayOutputStream baos = new ByteArrayOutputStream(); bitmap.compress(Bitmap.CompressFormat.JPEG, 50, baos); File file = new File(Environment.getExternalStorageDirectory() + "/temp.jpg"); try { file.createNewFile(); FileOutputStream fos = new FileOutputStream(file); InputStream is = new ByteArrayInputStream(baos.toByteArray()); int x = 0; byte[] b = new byte[1024 * 100]; while ((x = is.read(b)) != -1) { fos.write(b, 0, x); } fos.close(); } catch (Exception e) { e.printStackTrace(); } return file;}
