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
<provider
android:name="androidx.core.content.FileProvider"
android:authorities="me.xifengwanzhao.provider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/file_paths" />
</provider>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

//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

相册和 拍照都已经vc 完毕 接下来就是 回调了
@Override
protected 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file
public 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;
}
