可能是最精简的Android6.0运行时权限处理方式
#使用方式
以打开相机为例
####1、首先AndroidManifest
中配置必要的权限
<uses-permission android:name="android.permission.CAMERA"/>
####2、在基类中加上回调方法
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[]
grantResults) {
XPermissionUtils.onRequestPermissionsResult(requestCode, permissions, grantResults);
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
}
####3、调用工具类方法 1>拒绝后无提示
XPermissionUtils.requestPermissions(Context context, int requestCode, String[] permissions, OnPermissionListener listener)
2>拒绝后再次申请给出提示
XPermissionUtils.requestPermissions(Context context, int requestCode, String[] permissions, OnPermissionListener listener, RationaleHandler handler)
这里主要注意这个Context必需是一个Activity
如果在Activity中可以传this
;
如果在Fragment中传getActivity()
;
如果在View中传getContext()
;
等等.....
private void doOpenCamera() {
XPermissionUtils.requestPermissions(this, RequestCode.CAMERA, new String[]{Manifest
.permission.CAMERA}
, new XPermissionUtils.OnPermissionListener() {
@Override
public void onPermissionGranted() {
if (PermissionHelper.isCameraEnable()) {
Toast.makeText(MainActivity.this, "打开相机操作", Toast.LENGTH_LONG).show();
} else {
DialogUtil.showPermissionManagerDialog(MainActivity.this, "相机");
}
}
@Override
public void onPermissionDenied(String[] deniedPermissions) {
Toast.makeText(context, "获取相机权限失败", Toast.LENGTH_SHORT).show();
if (XPermissionUtils.hasAlwaysDeniedPermission(context, deniedPermissions)) {
DialogUtil.showPermissionManagerDialog(MainActivity.this, "相机");
}
}
}, new XPermissionUtils.RationaleHandler() {
@Override
protected void showRationale() {
new AlertDialog.Builder(context)
.setTitle("温馨提示")
.setMessage("我们需要相机权限才能正常使用该功能")
.setNegativeButton("取消", null)
.setPositiveButton("验证权限", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
requestPermissionsAgain();
}
}).show();
}
});
}
####4、一次申请多个权限
用户可能部分拒绝,因此在onPermissionDenied(String[] deniedPermissions)
回调中返回了请求结果中所有被拒绝的权限,用户可用于比对判断出哪些权限被拒绝,给用户明确的提示
private void doMorePermission() {
XPermissionUtils.requestPermissions(this, RequestCode.MORE, new String[]{Manifest.permission.WRITE_CONTACTS,
Manifest.permission.READ_SMS}, new XPermissionUtils.OnPermissionListener() {
@Override
public void onPermissionGranted() {
Toast.makeText(context, "获取联系人,短信权限成功", Toast.LENGTH_SHORT).show();
}
@Override
public void onPermissionDenied(String[] deniedPermissions) {
StringBuilder sBuider = new StringBuilder();
for (String deniedPermission : deniedPermissions) {
if (deniedPermission.equals(Manifest.permission.WRITE_CONTACTS)) {
sBuider.append("联系人");
sBuider.append(",");
}
if (deniedPermission.equals(Manifest.permission.READ_SMS)) {
sBuider.append("短信");
sBuider.append(",");
}
}
if (sBuider.length() > 0) sBuider.deleteCharAt(sBuider.length() - 1);
Toast.makeText(context, "获取" + sBuider.toString() + "权限失败", Toast.LENGTH_SHORT).show();
if (XPermissionUtils.hasAlwaysDeniedPermission(context, deniedPermissions)) {
DialogUtil.showPermissionManagerDialog(MainActivity.this, sBuider.toString());
}
}
});
}
