saadaAB.setDisplayShowHomeEnabled(true);
}
}
I want to print a logo in action bar in my app but this code make that logo in center and remove text in action bar.
you can achieve it in 2 ways
1. if Apptheme is in
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="colorAccent">#color/colorAccent</item>
</style>
You can just call
getSupportActionBar().setHomeAsUpIndicator(R.drawable.squarebox);// set drawable icon
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
2. or you can customize toolbar like
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.v7.widget.Toolbar
android:id="#id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"/>
</android.support.design.widget.AppBarLayout>
<!-- Here goes your UI -->
</LinearLayout>
with java
Toolbar toolbar = findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
toolbar.setNavigationIcon(R.drawable.custom_icon);

I want the navigation view to be only visible when the hamburger icon in the toolbar is clicked. Every tutorial I followed did the same things with me, however mine doesn't show inside the toolbar.
Pass toolbar instance during initiation of ActionBarDrawerToggle
actionBarDrawerToggle = new ActionBarDrawerToggle(this,drawerLayout, toolbar, R.string.open,R.string.close);
First of all, I know this question has been asked before, I've spent an hour looking through other solutions, mostly from - getActionBar() returns null , and none have worked so another pair of eyes might be able to do something.
NavigationDrawer class which other classes inherit from:
public class NavigationDrawer extends AppCompatActivity {
String[] mDrawerTitles;
DrawerLayout mDrawerLayout;
ListView mDrawerList;
ActionBarDrawerToggle mDrawerToggle;
String activityTitle;
#Override
protected void onCreate(Bundle savedInstanceState) {
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
super.onCreate(savedInstanceState);
setContentView(R.layout.navigation_drawer_layout);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
mDrawerTitles = getResources().getStringArray(R.array.drawer_array);
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawerList = (ListView) findViewById(R.id.left_drawer);
activityTitle = getTitle().toString();
getSupportActionBar().setDisplayHomeAsUpEnabled(true); //here is where the error is thrown
getSupportActionBar().setHomeButtonEnabled(true);
addDrawerItems();
navDrawerSetup();
}

In NavigationDrawer activity you are performing setContentView(R.layout.navigation_drawer_layout), and in navigation_drawer_layout there is no any Toolbar, which leads to an exception.
Doing the following in you NavigationDrawer.class
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar); //This is null
setSupportActionBar(toolbar);
You are setting Activity toolbar to null, because there is no view in your R.layout.activity_main with R.id.toolbar ID. So when you try to set toolbar after the code above, you are trying to set a property in a null object, that produces a null pointer exception.
Remove the two lines above in your activity or declare a Toolbar view with R.id.toolbar ID on your R.layout.activity_main layout file. Doing that you will solve the problem.
I want to add an autocompletetextview component inside the action bar of a AppCompatActivity. My code is:
styles.xml
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="colorAccent">#color/colorAccent</item>
</style>
MainActivity.java
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Thread.setDefaultUncaughtExceptionHandler(new GlobalException());
Toolbar tb = (Toolbar) findViewById(R.id.toolbar_search);
setSupportActionBar(tb);
}
layout/action_bar_search.xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar

android:id="#+id/toolbar_search"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"
app:layout_scrollFlags="scroll|enterAlways"
app:layout_collapseMode="pin">
<AutoCompleteTextView
android:id="#+id/theSearch"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:ems="10"
android:hint="#string/search_the"
android:imeOptions="actionSearch"
android:inputType="textAutoComplete|textAutoCorrect"
android:textColor="#FFFFFF" >
<requestFocus />
</AutoCompleteTextView>
</android.support.v7.widget.Toolbar>
When my app opens, I see a blank white screen and after several seconds, it becomes a blank black screen that stays this way forever, until I stop it manually. Any idea?
Apparently, after Toolbar tb = (Toolbar) findViewById(R.id.toolbar_search); tb is null
Your Toolbar XML is not included in your R.layout.activity_main so findById will not work. This results in the Toolbar staying null and crashing your application. You can include layout resources with an <include> tag. In your case: <include layout="#layout/action_bar_search"/>.
Below is the example code for AutocompleteTextView:
AutoCompleteTextView text;
String[] languages={"Android ","java","IOS","SQL","JDBC","Web services"};
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
text=(AutoCompleteTextView)findViewById(R.id.theSearch);
ArrayAdapter adapter = new ArrayAdapter(this,android.R.layout.simple_list_item_1,languages);
text.setAdapter(adapter);
text.setThreshold(1);
}
I hope that will help you....

android:fitsSystemWindows is for making status bar and/or navigation bar transparent. I am not aware that it can be applied to Toolbar.
As for changing navigation bar's colour part, you can do it like this:
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
// clear FLAG_TRANSLUCENT_STATUS flag:
window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
// add FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS flag to the window
window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
// finally change the color
window.setStatusBarColor(rgbColor);
}
And for Toolbar you can do it in XML by setting app:contentScrim="?attr/colorPrimary" property to CollapsingToolbarLayout, or in code:
collapsingToolbarLayout.setContentScrimColor(toolbarColor);
collapsingToolbarLayout.setExpandedTitleColor(textColor);
collapsingToolbarLayout.setCollapsedTitleTextColor(textColor);
I have a problem with my custom Navigation Drawer. When I compile my application the following error messages :
This Activity already has an action bar supplied by the window decor. Do not request Window.FEATURE_ACTION_BAR and set windowActionBar to false in your theme to use a Toolbar instead.
MainAcitvity.java :
public class MainActivity extends ActionBarActivity {}

Then in OnCreate() I have :
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
...
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeButtonEnabled(true);
mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout, toolbar,

public void onDrawerClosed(View view) {
getActionBar().setTitle(mTitle);
invalidateOptionsMenu();
}
public void onDrawerOpened(View drawerView) {
getActionBar().setTitle(mDrawerTitle);`enter code here`
invalidateOptionsMenu();
}
};
mDrawerLayout.setDrawerListener(mDrawerToggle);
Edit your style XML and override or replace "Theme.AppCompat.Light.NoActionbar"
In place of what you are currently using.
