举例说明Android运行时权限用法

本文主要是介绍举例说明Android运行时权限用法，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

运行时权限是API-23时候新加的，允许在运行时动态授予权限

##废话不多说，直接上代码

public static final int MULTIPLE_PERMISSIONS = 10; // code you want.String[] permissions = new String[] {Manifest.permission.WRITE_EXTERNAL_STORAGE,Manifest.permission.CAMERA,Manifest.permission.ACCESS_COARSE_LOCATION,Manifest.permission.ACCESS_FINE_LOCATION
};@Override
void onStart() {if (checkPermissions())// permissions granted.    } else {// show dialog informing them that we lack certain permissions}
}private boolean checkPermissions() {int result;List<String> listPermissionsNeeded = new ArrayList<>();for (String p:permissions) {result = ContextCompat.checkSelfPermission(getActivity(),p);if (result != PackageManager.PERMISSION_GRANTED) {listPermissionsNeeded.add(p);}}if (!listPermissionsNeeded.isEmpty()) {ActivityCompat.requestPermissions(this, listPermissionsNeeded.toArray(new String[listPermissionsNeeded.size()]), MULTIPLE_PERMISSIONS);return false;}return true;
}@Override
public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {switch (requestCode) {case MULTIPLE_PERMISSIONS:{if(grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED){// permissions granted.} else {// no permissions granted.}return;}}
}

So easy！！！
