I have modified the tabbed activity example to create my own set of 3 tabs. Each tab has its own layout file and uses this theme:
<style name="AppTheme" parent="android:Theme.Holo.Light.NoActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="colorAccent">#color/colorAccent</item>
</style>
Everything was working perfectly until I added an EditText to one of the fragments layout files. Then next time i built the app and ran it on an emulator the EditText did not render (however space was left for it). I then tried to add different types of text fields. Most of them were to the same effect but the Person Name one had 'name' render next to it as it should but the input box did not show again. This is the fragment layout file:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
tools:context="com.*********.************.MainActivity$FragmentTransmit">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceLarge"
android:text="Transmit"
android:id="#+id/textView"
android:layout_alignParentTop="true"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true" />
<Button
style="?android:attr/buttonStyleSmall"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="New Button"
android:id="#+id/button"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_below="#+id/textView" />
<EditText
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/editText"
android:layout_below="#+id/button"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_alignParentRight="true"
android:layout_alignParentEnd="true"
android:clickable="true"/>
To conclude, I'm using the Holo theme with no action bar in a fragment and everything works except when the app is built and ran edit texts don't show. So my question to you is Why it is not shown? and How it can be made to be shown?
Edit: Using a Nexus 5X emulator

i am new to Android and i might have a silly / dumb Question. I have got an Activity where i want to dynamically create Multiple Input Fields. The amount of Input Fields is defined by the User.
Because the Input is Styled and Consists of 2 Elements and didnt want to Create these Elements every Time because of Elements have got multiple Parameters that are the same every time. Thats why i created a XML File just for this two Elements which i would like to use in my Programm to Create the Inputs.
View_input.xml

val view = inflater.inflate(R.layout.view_input, LinearLayout(this))

found the solution ,get your inflator from activity not application just modify your initLayout() like this
// here is the fix
val inflater = getSystemService(Context.LAYOUT_INFLATER_SERVICE) as LayoutInflater
just set the theme on the chip itself using android:theme="#style/Theme.MaterialComponents.Bridge:
<com.google.android.material.chip.Chip

app:chipStrokeWidth="1dp"
app:textEndPadding="10dp"
app:textStartPadding="10dp"
tools:chipText="my chip"
tools:text="Fortune" />
If you don't want your view to change and with on tool bar try this,
<style name="AppTheme" parent="Theme.MaterialComponents.DayNight.NoActionBar.Bridge"/>
I have a listview with items and a searchview in my toolbar. When the user clicks on the search icon the keyboard appears. There's a problem which drives me nuts. When the keyboard appears the user can't scroll to the last four items and yes I tried android:windowSoftInputMode="adjustResize" and android:windowSoftInputMode="adjustPan", but they did nothing.

Original answer
I would suggest to implement a SearchDialog Activity.
It shows a pop-up dialog for suggestions and, being a dialog, doesn't go behind the keyboard.
Read this official Android guide for more information.
https://developer.android.com/guide/topics/search/search-dialog#SearchDialog
I am building an app that has 3 pages to display. To do so, I'm using a tabbed activity.
My tabbed activity works fine with textviews, buttons, etc. By works fine I mean that I can see the tabs bar at all times and can navigate between tabs.
Now, I'm trying to populate a listview within one of the tabs. This listview uses custom rows I built. I am populating this listview upon launch using an arraylist and an adapter then displaying it.
Now, the problem is that whenever the listview populates the page using my custom rows(routelistingrow.xml), the list view immediately takes over the activity full screen and covers the tabs bar and the app is stuck in this listview.
I then tried doing these steps using a basic activity (without any tabs) just to see if the listview would stay in the right place and avoid taking control of the screen. And this worked, the action bar was always visible.
So the problem is when I try to display this listview among one of many pages.
I used this video for the tabs
https://www.youtube.com/watch?v=ediklbippkA
I also tried using fragments within a navigation drawer rather than tabs and still got the same problem.
So I would like to know what's causing this problem and why the listview acts this way when I try to populate it from main.
I also found that this problem occurs when I try to dynamically add rows upon a button click
I left my Main2Activity as default and added the following:
#Override
protected void onCreate(Bundle savedInstanceState) {
setContentView(R.layout.tab_routelistings);
listView = findViewById(R.id.routelistingslistview);
dataModels= new ArrayList<>();
dataModels.add(new RouteTemplate("Canada", "USA"));
dataModels.add(new RouteTemplate("USA", "Canda"));
dataModels.add(new RouteTemplate("Canada", "USA"));
dataModels.add(new RouteTemplate("USA", "Canda"));
dataModels.add(new RouteTemplate("Canada", "USA"));
dataModels.add(new RouteTemplate("USA", "Canda"));
adapter = new RouteAdapter(dataModels, getApplicationContext());
listView.setAdapter(adapter);
}
//i only added the switch statement within this method found in main2activity.
public class SectionsPagerAdapter extends FragmentPagerAdapter {
public SectionsPagerAdapter(FragmentManager fm) {
super(fm);
}
#Override
public Fragment getItem(int position) {
// getItem is called to instantiate the fragment for the given page.
// Return a PlaceholderFragment (defined as a static inner class below).
switch(position)
{
case 0:
TabRouteListings tabRouteListings = new TabRouteListings();
return tabRouteListings;
case 1:
TabCreateRoute tabCreateRoute = new TabCreateRoute();
return tabCreateRoute;
default:
TabRouteListings tabRouteListings2 = new TabRouteListings();
return tabRouteListings2;
}
}
TabCreateRoute.java

I've been struggling with this for the past 3 days and would like to know if I'm better off proceeding with a different method (in case you can't find a solution).
As u mentioned ur tab view is overlapped by list view, Try below solution
U can put android:paddingBottom= "10dp" in root linearLayout in TabRouteListings.xml
And change android:layout_width="match_parent" in listView in TabRouteListings.xml . This change is not directly related for ur requirement
I have an app with a splash screen view that looks like this:

It renders an image scaled and centered into the screen. Unfortunately, this isn't working well for us. It causes a slight flash of white before it loads the view. My solution was to use an activity style. That works great, except I can't seem to center AND scale the image. I can center it easily, but it is wider than the screen. Here is my xml drawable:
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#android:color/black"/>
<item>
<bitmap
android:gravity="center|bottom|clip_vertical"
android:src="#drawable/splash2"
/>
</item>
</layer-list>
How do I scale and center that splash2 image?
You can make the image in Photoshop, put it in the xml then center the whole thing, but I would recommend having a Splash screen while loading the app, because if you have it with a timer it wastes user's time...
So that's what I did to have a splash screen like this one:
First, you have to add a new Java class, let's call it SplashActivity.java
You don't have to add much to it:
package YOUR-PACKAGE-NAME;
import android.content.Intent;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
public class SplashActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
Intent i = new Intent(SplashActivity.this, MainActivity.class);
startActivity(i);
finish();
}
}
After that, you have to have a drawable for the splash screen, because if you have a layout it will appear when the app is already loaded, so there won't be any sense in the Splash...
Go to the drawable folder and create a file named background_splash.xml.
There you add
<?xml version="1.0" encoding="utf-8"?>
<layer-list
xmlns:android="http://schemas.android.com/apk/res/android"
android:gravity="center">
<item>
<bitmap
android:src="#drawable/ic_splash"
/>
</item>
</layer-list>
where ic_splash is the image I created with Photoshop with resolution 1280x720 and then created a 9-patch image... (You have to have the 9-patch image, not to have normal, small and cropped image on different devices..) So go here and generate yours... Create it, download it and copy all the folders (mdpi, hdpi etc) to your res folder...
Now, go to your values/styles.xml and add the NoActionBar style
<style name="SplashTheme" parent="Theme.AppCompat.NoActionBar">
<item name="android:windowBackground">#drawable/background_splash</item>
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
</style>
THEN open your Manifest.xml and edit the activity with intent-filter.
Yours should be
<activity
android:name=".MainActivity"
android:label="#string/app_name"
android:icon="#drawable/ic_launcher"
android:theme="#style/AppTheme"
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
so replace the .MainActivity with .SplashActivity and the .MainActivity as another activity, so in the end you should have at least two activities declared at the Manifest.xml:
<activity
android:name=".SplashActivity"
android:theme="#style/SplashTheme"
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".MainActivity"
android:label="#string/app_name"
android:icon="#drawable/ic_launcher" or "#mipmap/ic_launcher"
android:theme="#style/AppTheme">
</activity>
Good luck! :)
If there are any troubles, ask :)
I am working on a xamarin project (has no relevance here as far as I can tell - the android layout properties are the same)
I am using Window.SetFeatureInt (WindowFeatures.CustomTitle, ...) to set the title (2 "columns". I wish to make two rows of text though for my title. Is this possible? I have not had much success. I have an upper left, upper right and lower left and lower right TextViews to set.
My previous attempts have ended up with the TextViews overwriting each other.
Here I am designing a XML file with an image, text for title & button. This is the XML file. U can use it however you want, for a complete application or perticular activity.
In case of activity add this activity's theme tag. For multi line just use text view in side the below linear layout, set it as multline true.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="35dip"
android:gravity="center_vertical"
android:background="#android:color/darker_gray">
<ImageView
android:id="#+id/header"
android:background="#drawable/icon"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Custom Window Text"
android:textColor="#android:color/black"
android:textStyle="bold"/>
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button" />
Create a theme in Custom_theme.xml,
<resources>
<style name="CustomWindowTitleBarBG">
<item name="android:background">#323331</item>
</style>
<style name="TitleBarTheme" parent="android:Theme">
<item name="android:windowTitleSize">35dip</item>
<item name="android:windowTitleBackgroundStyle"> #style/CustomWindowTitleBarBG</item>
</style>
Modify the AndroidManifest.xml file as follows for applying custom theme
<application
android:icon="#drawable/icon"
android:label="#string/app_name"
android:theme="#style/TitleBarTheme" >
<activity
android:name=".CustomWindowTitle"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
Now in main java file add “requestWindowFeature(Window.FEATURE_CUSTOM_TITLE)” &
“getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.window_title)”
This is the code snippet for CustomWindowTitle.java
package com.example.android;
import android.app.Activity;
import android.os.Bundle;
import android.view.Window;
public class CustomWindowTitle extends Activity
{
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);
setContentView(R.layout.main);
getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.window_title);
}
}
