Name of my app not showing on top of activity. Showing "com.example.(appname).(file name)

When first starting a simple app, usually the title of the app is on the top of the activity. However, for me, it says com.example.inventory.MainActivity and then when I switch activities to another one, it'll say com.example.inventory.AddProduct
This is my AndroidManifest.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.inventory">
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:roundIcon="#mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="#style/AppTheme">
<activity android:name=".ProductList"></activity>
<activity android:name=".AddProduct" />
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
I'm a beginner so sorry if I forgot to include any other important file.

You need to add a label for your activity like this:
<activity android:name=".ProductList"
android:label = "Product Screen"></activity>
Replace Product Screen with the Title of your choice.
Do the same for all the other activities in the Manifest.xml

Keyboard below the fragment view

this is what i want
I am using the BottomsheetFragment what i want is the keyboard should be below the view . but in my case keyboard is overlaping the fragment view .
here is my xml file check my code here
and i am getting this output

I have created a sample app and tested on the bottomsheet xml provided
by you. By adding
android:windowSoftInputMode="stateAlwaysHidden|adjustResize" in
manifest file did work.
So Manifest file looks as below.
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:roundIcon="#mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="#style/AppTheme">
<activity
android:name=".MainActivity"
android:label="#string/app_name"
android:theme="#style/AppTheme.NoActionBar"
android:windowSoftInputMode="stateAlwaysHidden|adjustResize">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
Alternatively you can set this attribute dynamically as well inside onCreate in Activity class as follows
getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN | WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE);
I have tried both ways on an sample app

Remove Action Bar Android

Hi to android stack overflow communities,
I want to remove the action bar which contain the title and the three dots. I have tried some of the solutions such as android:theme="#android:style/Theme.NoTitleBar" but, the app went crash.
Is there any possible other solution? Thanks

This is the nuclear option.
Replace
public class MainActivity extends ActionBarActivity
with
public class MainActivity extends Activity
in all the Activitys where you don't want ActionBar.
And to remove the three-dots button, add
#Override
public boolean onPrepareOptionsMenu(Menu menu) {
return false;
}
to your Activity.
Try this. This will work.

You have to use Activity not ActionBarActivity. So extends your javaclass from Activity. For removing the three dots remove onCreateOptionsMenu method from your Activity.

Create Your code like this
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".MainActivity"
android:label="#string/app_name"
android:screenOrientation="portrait"
android:theme="#android:style/Theme.Black.NoTitleBar" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
Enter this line android:theme="#android:style/Theme.Black.NoTitleBar" in Activity

You just need to call function
getActionBar().hide();
Tthis will hide action bar for you simply.

Search activity not being launched when pressing enter

Search activity not being launched when pressing enter.The search view is shown nicely on the action bar. But when i type the search query and press enter

Here is the Menu.xml
<menu xmlns:android="http://schemas.android.com/apk/res/android"

<!-- Search, should appear as action button -->

android:title="#string/action_search"
com.punit.rateit:actionViewClass="android.widget.SearchView"
com.punit.rateit:showAsAction="ifRoom"
/>
</menu>
The activity which shows action bar.
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.menu,menu);
SearchManager searchManager =
(SearchManager) getSystemService(Context.SEARCH_SERVICE);
SearchView searchView =
(SearchView) menu.findItem(R.id.search).getActionView();
searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
searchView.setIconifiedByDefault(false);
searchView.setSubmitButtonEnabled (true);
return super.onCreateOptionsMenu(menu);
}
The SearchResult activity which should be the activity called when search submit button is pressed
public class SearchResultsActivity extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Log.d("search", "search triggered");
setContentView(R.layout.searchpage);
handleIntent(getIntent());
}
#Override
protected void onNewIntent(Intent intent) {
Log.d("search", "search triggered");
setIntent(intent);
handleIntent(intent);
}
private void handleIntent(Intent intent)
{
if (Intent.ACTION_SEARCH.equals(intent.getAction())) {
String query = intent.getStringExtra(SearchManager.QUERY);
Log.d("search", query);
}
}
#Override
public boolean onSearchRequested() {
Log.d("search", "search triggered");
return false; // don't go ahead and show the search box
}

After a long Research i have Analyse something
searchView.setSearchableInfo( searchManager.getSearchableInfo(new
ComponentName(this,SearchResultsActivity.class)));
Here the activity.class is the name of the searchable activity where you want to pass the search query.

I had the same problem, and my search for an answer took me here, so here is what worked for me...
Make sure your searchables.xml file is in the correct location (i.e,
in your res/xml/ folder) and that the same file does not contain any
errors - otherwise you will find that
(SearchManager)getSystemService(Context.SEARCH_SERVICE).getSearchableInfo(componentName)
will return null, breaking your search functionality.
(Also, ensure you set componentName in the appropriate manner,
because the example shown in the Android guide is for only when you
are making searches and displaying searches in the same Activity.)
...am sharing in the hope it may save someone else a wasted 4 hours! :/

Solved the problem. The tag
was needed to be for application .Removing it from activity and putting it under application did the trick.
Here is the latest application tag in manifest.xml
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme"
>
<meta-data android:name="android.app.default_searchable" android:value=".SearchResultsActivity"/>
<activity
android:name="com.punit.rateit.MainActivity"
android:label="#string/app_name" >
<meta-data android:name="android.app.default_searchable"
android:value="com.punit.rateit.SearchResultsActivity" />
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>

Creating a ComponentName object with the name of the Search Result activity class worked for me. Like this:
searchView.setSearchableInfo(searchManager.getSearchableInfo(new ComponentName(this, SearchStoreActivity.class)));

I was not using the strings within searchable.xml.
You MUST set it up that way or you will get null. I had just put in text instead of using #string.
<?xml version="1.0" encoding="utf-8"?>
<searchable xmlns:android="http://schemas.android.com/apk/res/android"
android:label="#string/app_label"
android:hint="#string/search_hint" >
</searchable>

I struggled with the problem for a day or two, it's not very clearly mentioned in the documentation.
searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
In the above the getComponentName function returns the name of the
current component, which is good if your current component is
handling/showing the search results, but if you have a different
activity then you need to put the component name of that activity for
search view to redirect searches to that activity.
searchView.setSearchableInfo(searchManager.getSearchableInfo(new ComponentName(this, SearchResultActivity.class)));
Also make sure to have no errors in searchable.xml file in res/xml folder.

SearchInfo always coming out null

I'm having trouble setting up the search view in the action bar.
I followed the developer site, but it doesn't work. I get the feeling that I am missing something.
When I run my code, it always outputs "failed to get searchable info" (MainActivity.setupSearchView()).
MainActivity.java
// package...
// imports...
public class MainActivity extends Activity {
private static String tag = "Main Activity";
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater mi = getMenuInflater();
mi.inflate(R.menu.search_view, menu);
setupSearchView(menu);
return true;
}
private void setupSearchView(Menu menu) {
SearchManager sm = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
SearchableInfo si = sm.getSearchableInfo(getComponentName());
if (si == null) {
Log.wtf(tag, "failed to get searchable info");
return;
}
SearchView sv = (SearchView) menu.findItem(R.id.menu_search).getActionView();
sv.setSearchableInfo(si);
// Do not iconify the widget; expand it by default
sv.setIconifiedByDefault(false);
}
}
SearchResultsActivity.java
// package...
// imports...
public class SearchResultsActivity extends ListActivity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
final Intent queryIntent = getIntent();
doSearchQuery(queryIntent);
}
#Override
public void onNewIntent(final Intent newIntent) {
super.onNewIntent(newIntent);
final Intent queryIntent = getIntent();
doSearchQuery(queryIntent);
}
}
searchable.xml
<?xml version="1.0" encoding="utf-8"?>
<searchable xmlns:android="http://schemas.android.com/apk/res/android"
android:hint="#string/search_hint"
android:label="#string/search_label" >
</searchable>
AndroidManifest.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="kpaek.examples"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk android:minSdkVersion="15" />
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name" >
<activity
android:name=".search.MainActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name=".SearchResultsActivity">
<intent-filter>
<action android:name="android.intent.action.SEARCH" />
</intent-filter>
<meta-data
android:name="android.app.searchable"
android:resource="#xml/searchable" />
</activity>
</application>
</manifest>

The key thing I found is that searchable.xml must not contain literal strings, only resources. I wasted about half a day on that one, since it causes getSearchableInfo to fail silently.

In my case using custom tags in res/menu/mymenu.xml worked for me:
app:showAsAction="ifRoom|collapseActionView"
app:actionViewClass="android.support.v7.widget.SearchView"
Do not use:
android:showAsAction="ifRoom|collapseActionView"
android:actionViewClass="android.support.v7.widget.SearchView"

I have found that the intent-filter and the meta-data elements must be included in the manifest activity element from which the search is initiated (MainActivity having a SearchView) for the method getSearchableInfo(getComponentName()) to return the correct configuration and not null.
<activity
android:name=".MainActivity"
android:label="#string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
<intent-filter>
<action android:name="android.intent.action.SEARCH" />
</intent-filter>
<meta-data
android:name="android.app.searchable"
android:resource="#xml/searchable" />
</activity>
I wonder if instead (and the solution I am going with for now) one should leave the intent and meta-data on the results activity declaration and change the argument to getSearchableInfo() as follows:
<activity android:name=".SearchResultsActivity">
<intent-filter>
<action android:name="android.intent.action.SEARCH" />
</intent-filter>
<meta-data
android:name="android.app.searchable"
android:resource="#xml/searchable" />
</activity>
And the changes to MainActivity (note the assignment statement for searchableInfo):
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu_search, menu);
SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
SearchView mySearchView = (SearchView) menu.findItem(R.id.action_search).getActionView();
SearchableInfo searchableInfo = searchManager.getSearchableInfo(new ComponentName(getApplicationContext(), SearchResultsActivity.class));
mySearchView.setSearchableInfo(searchableInfo);
return true;
}

This killed me for a day - I thought it was ActionBarSherlock-related, but no it works fine with that.
The problem was that I was trying to short-circuit the sample. At least one of your activities - the one you're doing the searching from is sufficient - must have this intent-filter in it in the manifest:
<intent-filter>
<action android:name="android.intent.action.SEARCH" />
</intent-filter>
If not, then searchManager.getSearchableInfo(getComponentName()) always returns null, and your configuration is ignored.

From the developersite:
A searchable configuration defines how the SearchView behaves and is
defined in a res/xml/searchable.xml file. At a minimum, a searchable
configuration must contain an android:label attribute that has the
same value as the android:label attribute of the or
element in your Android manifest.
As an example, they show:
<searchable xmlns:android="http://schemas.android.com/apk/res/android"
android:label="#string/app_name"
android:hint="#string/search_hint" />
app_name is, like in your manifest, the label of the activity. However, in your searchable, the label refers to search_label. Works perhaps if app_name and search_label are equal, but that seems fragile to me.

I encountered this issue but the advice above did not resolve it. Instead it turned out to be setting category default in the SearchResultActivity. For example the following breaks:
<activity android:name=".SearchResultActivity"
android:label="#string/app_name"
android:theme="#style/AppTheme">
<intent-filter>
<action android:name="android.intent.action.SEARCH" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
<meta-data
android:name="android.app.searchable"
android:resource="#xml/searchable" />
</activity>
Removing android.intent.category.DEFAULT resolves this problem.:
<activity android:name=".SearchResultActivity"
android:label="#string/app_name"
android:theme="#style/AppTheme">
<intent-filter>
<action android:name="android.intent.action.SEARCH" />
</intent-filter>
<meta-data
android:name="android.app.searchable"
android:resource="#xml/searchable" />
</activity>
Also the previous answers to this question have an error. MainActivity should be defined with android.app.default_searchable. android.app.searchable is only for your SearchResultsActivity.
<activity
android:name=".MainActivity"
android:label="#string/app_name">
<!-- other stuff-->
<meta-data android:name="android.app.default_searchable"
android:value=".SearchResultsActivity" />
</activity>
In conclusion the SearchManager is a fragile component prone to silent failures when the AndroidManifest.xml isn't perfect.

I wasted 8 full hours on this one because I checked all the above solutions but one thing was missing for me.
In my Android Manifest:
<meta-data
android:name="android.app.searchable"
android:value="#xml/searchable" />
Should has been:
<meta-data
android:name="android.app.searchable"
android:resource="#xml/searchable" />
For me it was failing silently. The best thing to do at first is just copy and paste the examples. Just be sure that all your attributes are exactly the same.
