一.概述 Android6.0发布一年多时间，带来了一些新的api变化，越来越多的手机倾向于使用Android6.0以上的系统，随之改变的是越来越多的项目要适配6.0的系统。
本篇文章目的就是对运行时权限处理的一个介绍，以及对目前权限相关的库的一些了解。
二.实现方式
原生实现方式
2.使用MPermissions框架
private static final int MY_PERMISSIONS_REQUEST_CAMERA =1; @OnClick({R.id.bt_scan_qrcode}) public void onViewClicked(View view) { switch (view.getId()) { case R.id.bt_scan_qrcode: //使用MPermissions来动态申请权限 MPermissions.requestPermissions(QRCodeActivity.this, MY_PERMISSIONS_REQUEST_CAMERA, Manifest.permission.CAMERA); break; } } @Override public void onRequestPermissionsResult( int requestCode, String[] permissions,int[] grantResults{ MPermissions.onRequestPermissionsResult(this, requestCode, permissions, grantResults); super.onRequestPermissionsResult(requestCode, permissions, grantResults); } @PermissionGrant(MY_PERMISSIONS_REQUEST_CAMERA) public void requestSdcardSuccess(){ Toast.makeText(this, "GRANT ACCESS SDCARD!", Toast.LENGTH_SHORT).show(); startActivity(new Intent(this, ScanQRCodeActivity.class)); } @PermissionDenied(MY_PERMISSIONS_REQUEST_CAMERA) public void requestSdcardFailed(){ Toast.makeText(this, "DENY ACCESS SDCARD!", private static final int MY_PERMISSIONS_REQUEST_CAMERA= 1; @OnClick({R.id.bt_scan_qrcode}) public void onViewClicked(View view) { switch (view.getId()) { case R.id.bt_scan_qrcode: //使用MPermissions来动态申请权限 MPermissions.requestPermissions(QRCodeActivity.this, MY_PERMISSIONS_REQUEST_CAMERA, Manifest.permission.CAMERA); break; } @Override public void onRequestPermissionsResult( int requestCode, String[] permissions,int[] grantResults){ MPermissions.onRequestPermissionsResult(this, requestCode, permissions, grantResults); super.onRequestPermissionsResult(requestCode, permissions, grantResults); } @PermissionGrant(MY_PERMISSIONS_REQUEST_CAMERA) public void requestSdcardSuccess(){ Toast.makeText(this, "GRANT ACCESS SDCARD!", Toast.LENGTH_SHORT).show(); startActivity(new Intent(this, ScanQRCodeActivity.class)); } @PermissionDenied(MY_PERMISSIONS_REQUEST_CAMERA) public void requestSdcardFailed(){ Toast.makeText(this, "DENY ACCESS SDCARD!", Toast.LENGTH_SHORT).show(); } }用法简单明了,对于onRequestPermissionsResult所有的Activity都是一致的，所以可以放到BaseActivity中去。此外，在Fragment中使用的方式一致，详见库(https://github.com/hongyangAndroid/MPermissions.)
