1.引入包
//引入阿里雲oss包
implementation 'com.aliyun.dpa:oss-android-sdk:+'
implementation 'com.squareup.okhttp3:okhttp:3.10.0'
implementation 'com.squareup.okio:okio:1.9.0'
implementation 'com.android.support:multidex:1.0.3'
implementation 'com.youth.banner:banner:1.4.10'
2.寫入開啟相機許可權和寫入SD卡的許可權，網路許可權
<!-- 往SDCard寫入資料許可權 --> <uses-permission android:name="android.permission. WRITE_EXTERNAL_STORAGE" /> <!--請求訪問使用照相裝置--> <uses-permission android:name="android.permission.CAMERA" />
3.寫入開啟相機的程式碼

private static final int CODE_CAMERA_REQUEST = 0xa1;
private static final int CODE_RESULT_REQUEST = 0xa2;
private static final int CAMERA_PERMISSIONS_REQUEST_CODE = 0x03;
private static final int STORAGE_PERMISSIONS_REQUEST_CODE = 0x04;
private File fileUri = new File(Environment.getExternalStorageDirectory().getPath() + "/photo.jpg");
private File fileCropUri = new File(Environment.getExternalStorageDirectory().getPath() + "/crop_photo.jpg");
private Uri imageUri;
private Uri cropImageUri;

}4.上傳圖片到阿里雲oss，使用下面方法必須繼承的是activity類
public void beginupload(Uri bitmap) {
Log.e("圖片地址",bitmap+"");
final String endpoint = "oss地址";
final String startpoint = "倉庫名字";
// 明文設定secret的方式建議只在測試時使用，更多鑑權模式請參考後面的`訪問控制`章節
OSSCredentialProvider credentialProvider = new OSSPlainTextAKSKCredentialProvider("keyid", "keysecret");
OSS oss = new OSSClient(getApplicationContext(), endpoint, credentialProvider);
//通過填寫檔名形成objectname,通過這個名字指定上傳和下載的檔案
// 構造上傳請求
final String objectname = TimeUtil.getTimeMis() + "";
final String url = startpoint +"."+ endpoint+"/"+ objectname;
PutObjectRequest put = new PutObjectRequest(startpoint, objectname, UiUtils.getImageAbsolutePath(SettingActivity.this,bitmap) );
// 非同步上傳時可以設定進度回撥
put.setProgressCallback(new OSSProgressCallback<PutObjectRequest>() {
@Override
public void onProgress(PutObjectRequest request, long currentSize, long totalSize) {
}
});
OSSAsyncTask task = oss.asyncPutObject(put, new OSSCompletedCallback<PutObjectRequest, PutObjectResult>() {
@Override
public void onSuccess(PutObjectRequest request, PutObjectResult result) {
//上傳成功後呼叫自己寫的傳到專案介面的方法
sethead(objectname);
}
@Override
public void onFailure(PutObjectRequest request, ClientException clientExcepion, ServiceException serviceException) {
// 請求異常
if (clientExcepion != null) {
// 本地異常如網路異常等
clientExcepion.printStackTrace();
}
if (serviceException != null) {
}
}
});
}到這裡，哪裡使用直接呼叫開啟相機或手機本地相簿方法就可以了
