My MainActivity uses onNavigationItemSelected(MenuItem item) that includes an activity. But somehow it won't open the other fragments that I have on the drawer. I can open the fragments if i delete navigationView.setNavigationItemSelectedListener(this). But then I can't open BookingActivity.
My MainActivity:
public class MainActivity extends AppCompatActivity implements NavigationView.OnNavigationItemSelectedListener {
//region Properties
private AppBarConfiguration mAppBarConfiguration;
ImageButton settings_btn;
//endregion
#Override
protected void onStart() {
super.onStart();
ProductDatabase productDb = new ProductDatabase();
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
settings_btn = findViewById(R.id.btn_settings);
settings_btn.setOnClickListener(v ->
startActivity(new Intent(MainActivity.this, SettingsActivity.class)));
FloatingActionButton fab = findViewById(R.id.fab);
fab.setOnClickListener(view -> Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
.setAction("Action", null).show());
DrawerLayout drawer = findViewById(R.id.drawer_layout);
NavigationView navigationView = findViewById(R.id.nav_view);
// Passing each menu ID as a set of Ids because each
// menu should be considered as top level destinations.
mAppBarConfiguration = new AppBarConfiguration.Builder(
R.id.nav_home, R.id.nav_login, R.id.nav_treatments, R.id.nav_product, R.id.nav_about, R.id.nav_contactUs)
.setDrawerLayout(drawer)
.build();
NavController navController = Navigation.findNavController(this, R.id.nav_host_fragment);
NavigationUI.setupActionBarWithNavController(this, navController, mAppBarConfiguration);
NavigationUI.setupWithNavController(navigationView, navController);
navigationView.setNavigationItemSelectedListener(this); // Fragments work if I remove this line, but not BookingActivity
}
#Override

please try this link How to go to fragment from activity

I am a newbie to Android Studio but have successfully gone quite far, including a successful login screen. But I am getting stuck at a point.
The navigation icon created using ActionBarDrawerToggle works fine on the homescreen. Then on clicking on any of the options, it successfully loads the fragment. But when I click on the the icon again to go to another fragment, the navigation drawer open but the application closes. The debugger shows no error, it only reports that the onStop and onPause events have been triggered (which are empty since I have no use with them).
I have tried a lot but I am unable to find a solution to this problem.
I even attempted to create a custom view on the ActionBar with a custom ImageButton, and I set a click listener. That worked fine, but I want to use the default method, i.e. ActionBarDrawerToggle.
Open to all suggestions!

maybe the onmylocation needs permissions ithink
ps: works perfect with android 4.4, the problem is with android 6.0 or higher
I also struggled with the runtime permissions when upgrading my app to a new Android version.
But I found this post very helpful:
https://inducesmile.com/android/android-6-marshmallow-runtime-permissions-request-example/
(The code below comes from this).
Basically, you need to check if you have the permissions in your App when you need them (perhaps during startup in your case) with code such as this;
if (ContextCompat.checkSelfPermission(WebActivity.this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(WebActivity.this, new String[]{Manifest.permission.ACCESS_COARSE_LOCATION}, MY_REQUEST_CODE);
}
Then, you need to handle a response in an onRequestPermissionsResult method
#Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
if (requestCode == MY_REQUEST_CODE) {
if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
//You have permission, so continue
}else if (grantResults[0] == PackageManager.PERMISSION_DENIED){
if (ActivityCompat.shouldShowRequestPermissionRationale(WebActivity.this, Manifest.permission.RECORD_AUDIO)) {
//Show an explanation to the user *asynchronously*
ActivityCompat.requestPermissions(WebActivity.this, new String[]{Manifest.permission.ACCESS_COARSE_LOCATION}, MY_REQUEST_CODE);
}else{
//Never ask again and handle your app without permission.
}
}
}
}
Don't forget that you still need the permissions to be specified in your MANIFEST file.
Hi guys perfect saturday for some coding :)
I have a navigation drawer where i can click on items and they direct me to fragments. But how i make so when i press an item in the navigation drawer to link me to a website. I'm not really good at items..
I will post three different imgur images See the 3 images here
So when you press it, example: www.google.com comes up in your regular "chrome app" i'm not really interested in webview cause of the website is not html5.
This is my MainActivity at the bottom of it you can find how i use the items for my fragments.
I'm a rookie programmer hehe... But it is so fun! Learning step by step.

You need something like this in your onClick method of a button, or listener, however you wanna handle the click event:
Intent intent = new Intent("android.intent.action.VIEW",
Uri.parse("http://www.google.com/"));
startActivity(intent);
If you don't know how to handle the click itself check this out., but I see in your code that you can, so it's fine.
Just add this on your menu item
Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("http://www.google.com"));
startActivity(browserIntent);
so on your onNavigationItemSelected you have to add another if and search for the id of the item you need:
I made an example
#Override
public boolean onNavigationItemSelected(MenuItem item) {
int id = item.getItemId();
if (id == R.id.action_settings) {
Intent intent = new Intent(this, SettingsActivity.class);
startActivity(intent);
return true;
}
else if (id == R.id.YOUR_ITEM_ID) {
Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("http://www.google.com"));
startActivity(browserIntent);
return true;
}
return true;
}
I am trying to use two framelayouts to load the content. My problem is both pages are showing data at the same time. I want to use setVisibilty method in the main java file. When one frame is showing data the other frame hides automatically. Could anyone tell me the java codes. Here is the xml file:
<FrameLayout
android:id="#+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent">

You could make a function to set them both, but then you will have to make sure you always use that function:
private void setFrameVisibility(boolean frameOneVisible) {
if (frameOneVisible) {
findViewById(R.id.content_frame).setVisibility(View.VISIBLE);
findViewById(R.id.content_frametwo).setVisibility(View.GONE);
} else {
findViewById(R.id.content_frame).setVisibility(View.GONE);
findViewById(R.id.content_frametwo).setVisibility(View.VISIBLE);
}
}
You can implement this by using this code:
inside onCreateView:
frameLayout1 = (FrameLayout) findViewById(R.id.frameLayout1);
frameLayout2 = (FrameLayout) findViewById(R.id.frameLayout2);
When ever you want to change visibility:
frameLayout1.setVisibility(View.VISIBLE);
frameLayout2.setVisibility(View.GONE);
