我想知道如何为经理设定价值？以下是我初始化PermissionManager管理器或PermissionManager manager = new？
的方法public PermissionManager manager = new PermissionManager(PermissionManager.mActivity, PermissionManager.mContext);
protected void onStart() {
super.onStart();
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
/*String[] list = new String[]{PermissionConsts.PHONE_STATE, PermissionConsts.READ_CONTACTS, PermissionConsts.READ_EXTERNAL_STORAGE,
PermissionConsts.READ_SMS};*/
manager.requestPermission(new String[]{Manifest.permission.ACCESS_FINE_LOCATION});
}
Intent serviceIntent = new Intent(this, LocationFetcherService.class);
startService(serviceIntent);
}
这里不起作用：
public boolean onNavigationItemSelected(MenuItem item) {
// Handle navigation view item clicks here.
int id = item.getItemId();
if (id == R.id.nav_camera) {
initLocationFetching(this);
}
}
这是BaseActivityLocation类
public class BaseActivityLocation extends AppCompatActivity implements LocationManagerInterface {
public SmartLocationManager mLocationManager;
public PermissionManager manager = new PermissionManager(BaseActivityLocation.this, BaseActivityLocation.this);
public LocationFetcherService mLocationFetcherService;
private static final int REQUEST_FINE_LOCATION = 1;
private Activity mCurrentActivity;
private int count = 0;
@Override
public void locationFetched(Location mLocation, Location oldLocation, String time, String locationProvider) {
// storing it on application level
GetAccurateLocationApplication.mCurrentLocation = mLocation;
GetAccurateLocationApplication.oldLocation = oldLocation;
GetAccurateLocationApplication.locationProvider = locationProvider;
GetAccurateLocationApplication.locationTime = time;
}
public void instatntiate(Activity mActivity){
/*3rd Parametr*/
//For One time Gps Usage: SmartLocationManager.USE_ONE_TIME_GPS;
//For every 10 seconds Gps Usage: SmartLocationManager.USE_UPDATE_TIME_GPS;
/*4th parameter*/
//For All netwrok Provider: SmartLocationManager.ALL_PROVIDERS;
//For Network Provider only: SmartLocationManager.NETWORK_PROVIDER;
//For GPS Provider only: SmartLocationManager.GPS_PROVIDER;
/*Last Parameter*/
//For using Any Api location: SmartLocationManager.ANY_API; //The priority will be google api.
//For using google Api location: SmartLocationManager.ONLY_GOOGLE_API;
//For using android Api Location: SmartLocationManager.ONLY_ANDROID_API;
mLocationManager = new SmartLocationManager(getApplicationContext(), mActivity, SmartLocationManager.USE_ONE_TIME_GPS, this, SmartLocationManager.ALL_PROVIDERS, LocationRequest.PRIORITY_HIGH_ACCURACY, 10 * 1000, 1 * 1000, SmartLocationManager.LOCATION_PROVIDER_RESTRICTION_NONE, SmartLocationManager.ANY_API); // init location manager
}
public void initLocationFetching(Activity mActivity) {
mCurrentActivity = mActivity;
try {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
manager = new PermissionManager(mCurrentActivity, getApplicationContext());
PermissionManagerInterface permissionManagerInterface = new PermissionManagerInterface() {
@Override
public void onPermissionGranted(String message, int requestCode) {
}
以下是Permission Manager类的代码，但我想要消除
的空值public class PermissionManager implements RequestPermissionsResultInterface {
public static Activity mActivity;
public static Context mContext;
public String[] permissionList;
public boolean flag;
private PermissionManagerInterface mManagerInterface = new PermissionManagerInterface() {
@Override
public void onPermissionGranted(String message, int requestCode) {
}
@Override
public void onPermissionDenied(String message, int requestCode) {
}
@Override
public void isAllGranted(boolean flag) {
}
};
public PermissionManager(Activity mActivity, Context mContext) {
this.mActivity = mActivity;
this.mContext = mContext;
}
public void requestPermission(String[] mList){
permissionList = mList;
ActivityCompat.requestPermissions(mActivity, mList, REQ_CODE);
}
public void getManagerInterface(PermissionManagerInterface mInterface){
mManagerInterface = mInterface;
}
@RequiresApi(api = Build.VERSION_CODES.M)
@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
if(requestCode == REQ_CODE){
for (int i = 0, len = permissions.length; i < len; i++) {
String permission = permissions[i];
String packageStrippedPermissionName = permissions[i].substring(permissions[0].lastIndexOf(".")+1);
if (grantResults[i] == PackageManager.PERMISSION_DENIED) {
// user rejected the permission
boolean showRationale = mActivity.shouldShowRequestPermissionRationale( permission );
if (! showRationale) {
AlertDialog.Builder builder = new AlertDialog.Builder(mActivity);
builder.setTitle(permission + " Required");
builder.setMessage("You have to grant this permission , otherwise app will not be able to continue, Click Yes to go to Settings else app will not resume!");
builder.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialogInterface, int i) {
Intent intent = new Intent(Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
Uri uri = Uri.fromParts("package", mActivity.getPackageName(), null);
intent.setData(uri);
mActivity.startActivityForResult(intent, REQ_CODE);
}
});
builder.setNegativeButton("No", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialogInterface, int i) {
Toast.makeText(mContext, "App will not Start without this Permission", Toast.LENGTH_SHORT).show();
mActivity.finish();
}
});
builder.setCancelable(false);
builder.show();
// user also CHECKED "never ask again"
// you can either enable some fall back,
// disable features of your app
// or open another dialog explaining
// again the permission and directing to
// the app setting
}else{
mManagerInterface.onPermissionDenied("\'" + packageStrippedPermissionName + "': permission denied", requestCode);
Alert(mActivity, permissions[i]);
}
}else if(grantResults[i] == PackageManager.PERMISSION_GRANTED){
mManagerInterface.onPermissionGranted("\'" + packageStrippedPermissionName + "\': permission granted", requestCode);
}
}
ArrayList<String> list = new ArrayList<>();
for(int k=0; k<grantResults.length; k++){
if(grantResults[k] == PackageManager.PERMISSION_GRANTED){
list.add(permissions[k]);
}
}
if(list.size() == permissions.length){
flag = true;
mManagerInterface.isAllGranted(flag);
}else{
flag = false;
mManagerInterface.isAllGranted(flag);
}
}
}
BaseActivityLocation java类：
BaseActivityLocation extends AppCompatActivity implements LocationManagerInterface {
public SmartLocationManager mLocationManager;
public PermissionManager manager = null;
public LocationFetcherService mLocationFetcherService;
private static final int REQUEST_FINE_LOCATION = 1;
private Activity mCurrentActivity;
private int count = 0;
@Override
public void locationFetched(Location mLocation, Location oldLocation, String time, String locationProvider) {
// storing it on application level
GetAccurateLocationApplication.mCurrentLocation = mLocation;
GetAccurateLocationApplication.oldLocation = oldLocation;
GetAccurateLocationApplication.locationProvider = locationProvider;
GetAccurateLocationApplication.locationTime = time;
}
protected void onStart() {
super.onStart();
manager = new PermissionManager(BaseActivityLocation.this, BaseActivityLocation.this);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
/*String[] list = new String[]{PermissionConsts.PHONE_STATE, PermissionConsts.READ_CONTACTS, PermissionConsts.READ_EXTERNAL_STORAGE,
PermissionConsts.READ_SMS};*/
manager.requestPermission(new String[]{Manifest.permission.ACCESS_FINE_LOCATION});
}
Intent serviceIntent = new Intent(this, LocationFetcherService.class);
startService(serviceIntent);
}
protected void onResume(){
super.onResume();
//showLocationPermission();
}
权限管理器界面
public interface PermissionManagerInterface extends Serializable
{
String TAG = PermissionManagerInterface.class.getSimpleName();
void onPermissionGranted(String message, int requestCode);
void onPermissionDenied(String message, int requestCode);
void isAllGranted(boolean flag);
}
答案 0 :(得分：0)
如果这是在活动中，请尝试此操作。 YourActivity是您的活动名称：
public PermissionManager manager = null;
protected void onStart() {
super.onStart();
manager = new PermissionManager(YourActivity.this, YourActivity.this);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
/*String[] list = new String[]{PermissionConsts.PHONE_STATE, PermissionConsts.READ_CONTACTS, PermissionConsts.READ_EXTERNAL_STORAGE,
PermissionConsts.READ_SMS};*/
manager.requestPermission(new String[]{Manifest.permission.ACCESS_FINE_LOCATION});
}
Intent serviceIntent = new Intent(this, LocationFetcherService.class);
startService(serviceIntent);
}
