在android 6.0开始，部分的权限需要我们动态申请，也就是说当我们的打开app的时候系统不会主动像您申请app所需要的部分权限，需要客户在使用app的时候主动的去申请。
一、权限的申请两步骤：
1、权限申请：
public static void requestPermissions(final @NonNull Activity activity,final @NonNullString[] permissions, final int requestCode)
2、申请回调处理：
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults)
二、Fragment中运行时权限的特殊处理
在Fragment中申请权限，不要使用ActivityCompat.requestPermissions, 直接使用Fragment的requestPermissions方法，否则会回调到Activity的onRequestPermissionsResult如果在Fragment中嵌套Fragment，在子Fragment中使用requestPermissions方 法，onRequestPermissionsResult不会回调回来，建议使用 getParentFragment().requestPermissions方法，
这个方法会回调到父Fragment中的onRequestPermissionsResult，加入以下代码可以把回调透传到子Fragment
@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
List fragments = getChildFragmentManager().getFragments();
if (fragments != null) {
for (Fragment fragment : fragments) {
if (fragment != null) {
fragment.onRequestPermissionsResult(requestCode,permissions,grantResults);
}
}
}
}
三、权限申请的简单封装
public class RequestPermissions {
public static intREQUEST_EXTERNAL_STORAGE = 1;
public static String[]PERMISSIONS_STORAGE = {
Manifest.permission.READ_EXTERNAL_STORAGE,
Manifest.permission.WRITE_EXTERNAL_STORAGE
};
public static voidwriteExternalStorage(final Context mContext, PermissionCallBack mCallBack) {
//检查是否拥有相应的权限
int permission =ActivityCompat.checkSelfPermission(mContext,Manifest.permission.WRITE_EXTERNAL_STORAGE);
//没有权限发起申请
if (permission !=PackageManager.PERMISSION_GRANTED) {
//6.0及以上版本才需要申请权限
if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.M)
ActivityCompat.requestPermissions((Activity) mContext,PERMISSIONS_STORAGE,REQUEST_EXTERNAL_STORAGE);
else {
mCallBack.setonPermissionListener(false);
}
} else {
mCallBack.setonPermissionListener(true);
}
}
public static voidwriteExternalStorage(final Context mContext, PermissionCallBack mCallBack, intrequestCode) {
//检查是否拥有相应的权限
int permission =ActivityCompat.checkSelfPermission(mContext,Manifest.permission.WRITE_EXTERNAL_STORAGE);
//没有权限发起申请
if (permission !=PackageManager.PERMISSION_GRANTED) {
//6.0及以上版本才需要申请权限
if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.M)
ActivityCompat.requestPermissions((Activity) mContext,PERMISSIONS_STORAGE,requestCode);
else {
mCallBack.setonPermissionListener(false);
}
} else {
mCallBack.setonPermissionListener(true);
}
}
public static void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions,@NonNull int[] grantResults, PermissionCallBack mCallBack) {
if (requestCode ==REQUEST_EXTERNAL_STORAGE) {
//判断权限是否申请成功
if(grantResults.length > 0 && grantResults[0] ==PackageManager.PERMISSION_GRANTED) {
mCallBack.setonPermissionListener(true);
} else {
mCallBack.setonPermissionListener(false);
}
return;
}
}
public static void openPre(final Context mContext) {
RemindDialogUtil.showRemindDialog(mContext, "當前無權限，將無法進行應用升級~,是否打开设置？", new RemindDialogUtil.DialogCallBack() {
@Override
public void clickYes() {
//跳转到设置页面，手动打开权限
Intent intent= new Intent();
intent.setAction(Settings.ACTION_APPLICATION_SETTINGS);
mContext.startActivity(intent);
RemindDialogUtil.hideRemindDialog();
}
@Override
public voidclickCancel() {
RemindDialogUtil.hideRemindDialog();
}
});
}
public interfacePermissionCallBack {
void setonPermissionListener(Boolean bo);
}
}
