I'm trying to implement Guillotine Menu by yalantis in my app.
I've put one button in the guillotine activity and have made a class for the guillotine activity. In that class I'm trying to implement the listener for the button .I've also a put a toast in that function but that's not getting displayed either.
Here is the guillotine activity:
<?xml version="1.0" encoding="utf-8"?>

android:background="#color/guillotine_background"

I am trying to create a button that when clicked opens a calendar using material design with android studio
but clicking it closes the app.
I implement the librery in the gradle
implementation 'com.google.android.material:material:1.3.0-alpha01'
This my code Java
package com.niccode.myapplication;
import androidx.appcompat.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import com.google.android.material.datepicker.MaterialDatePicker;
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button mdatePicker = findViewById(R.id.button);
MaterialDatePicker.Builder builder = MaterialDatePicker.Builder.datePicker();
builder.setTitleText("Select");
final MaterialDatePicker materialDatePicker = builder.build();
mdatePicker.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
materialDatePicker.show(getSupportFragmentManager(), "DATE_PICKER");
}
});
}
}
This is xml code
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"

<Button
android:id="#+id/button"
android:layout_width="wrap_content"

app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
</androidx.constraintlayout.widget.ConstraintLayout>
just change your appTheme to materialTheme in styles.xml:
<style name="AppTheme" parent="Theme.MaterialComponents.Light.NoActionBar">
Try below style
<style name="AppTheme" parent="Theme.MaterialComponents.Light.Bridge">
<!-- Customize your theme here. -->
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="colorAccent">#color/colorAccent</item>
<!-- Add these -->
<item name="materialCalendarStyle">#style/Widget.MaterialComponents.MaterialCalendar</item>
<item name="materialCalendarFullscreenTheme">#style/ThemeOverlay.MaterialComponents.MaterialCalendar.Fullscreen</item>
<item name="materialCalendarTheme">#style/ThemeOverlay.MaterialComponents.MaterialCalendar</item>

I've posted all the style to see if there's anything going wrong. Regardless that I would like the separator between the header and the body of the dialog I do not understand why the buttons do not appear.
Edit:
I read this
Missing buttons on AlertDialog | Android 7.0 (Nexus 5x)
and I realized that i need to define a style for my dialog.
Infact if i set this
<style name="AlertDialogTheme" parent="Theme.AppCompat.Light.Dialog.Alert">
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="colorAccent">#color/colorAccent</item>
<item name="windowActionBar">true</item>
<item name="windowNoTitle">false</item>
<item name="android:buttonBarStyle">#style/Widget.AppCompat.ActionButton</item>
</style>
and then initialize dialog in this way
AlertDialog.Builder builder = new AlertDialog.Builder(SettingActivity.this,R.style.dialog_theme);
I can see change of color and text. But wich is property to show title, separator and buttons?
if you want a customized layout. You need to create an instance of Dialog. i.e. Dialog dialog = new Dialog; and set the contentview for that dialog: dialog.setContentView(R.layout.my_customized_dialog_layout);
you can then create buttons inside that layout and initialize them.
I have two different styles of TabLayout in my app:
<style name="TabLayoutPower" parent="Widget.Design.TabLayout">
<item name="tabSelectedTextColor">#android:color/white</item>
<item name="tabTextColor">#android:color/white</item>
</style>
<style name="TabLayoutFree" parent="Widget.Design.TabLayout">
<item name="tabSelectedTextColor">#android:color/black</item>
<item name="tabTextColor">#android:color/black</item>
</style>
How can I define the default TabLayout style for a theme? I cannot find any info which item name should I use to build my theme. I'd like to add the TabLayout the same way I added my listview:
<style name="Free" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="colorPrimary">#color/black</item>
<item name="colorPrimaryDark">#color/black</item>
<item name="colorAccent">#color/main_red</item>
<item name="android:windowBackground">#color/main_bg_light</item>
<item name="android:listViewStyle">#style/MyListView</item>
</style>
For Support Library TabLayout, you can set tabStyle attribute in your theme:
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- ... -->
<item name="tabStyle">#style/AppTheme.TabLayout</item>
</style>
<style name="AppTheme.TabLayout" parent="Widget.Design.TabLayout">
<item name="tabSelectedTextColor">#android:color/white</item>
<item name="tabTextColor">#android:color/white</item>
</style>
If you wan to use 2 different styles for your TabLayout based on theme of your application then you should define your style inside attrs.xml
here is the Sample code for that
First you create an attrs.xml file ( Like this )
<?xml version="1.0" encoding="utf-8"?>
<resources>
<attr name="textColor" format="reference|color" />
<attr name="backColor" format="reference|color" />
<attr name="myTabStyle" format="reference" />
</resources>
define various theme as per your requirements inside styles.xml
Note: i have used 3 different themes for demo
<resources>
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="colorAccent">#color/colorAccent</item>
<item name="tabStyle">#style/TabLayoutPower</item>
<item name="textColor">#android:color/white</item>
<item name="backColor">#color/colorPrimary</item>
</style>
<style name="AppTheme2" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="colorPrimary">#android:color/holo_green_dark</item>
<item name="colorPrimaryDark">#android:color/white</item>
<item name="colorAccent">#android:color/holo_blue_dark</item>
<item name="textColor">#android:color/white</item>
<item name="tabStyle">#style/TabLayoutFree</item>
<item name="backColor">#FF00</item>
</style>
<style name="AppTheme3" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="colorPrimary">#ff00</item>
<item name="colorPrimaryDark">#ff0</item>
<item name="colorAccent">#0a91d4</item>
<item name="tabStyle">#style/TabLayoutNew</item>
<item name="textColor">#FF00</item>
<item name="backColor">#android:color/white</item>
</style>
<style name="TabLayoutPower" parent="Widget.Design.TabLayout">
<item name="tabSelectedTextColor">#android:color/white</item>
<item name="tabTextColor">#android:color/white</item>
</style>
<style name="TabLayoutFree" parent="Widget.Design.TabLayout">
<item name="tabSelectedTextColor">#android:color/holo_blue_bright</item>
<item name="tabTextColor">#android:color/holo_blue_bright</item>
</style>
<style name="TabLayoutNew" parent="Widget.Design.TabLayout">
<item name="tabSelectedTextColor">#android:color/holo_green_dark</item>
<item name="tabTextColor">#android:color/holo_green_dark</item>
</style>
</resources>
Now use this style in your TabLayout like this inside layout.xml files
Use like this style="?myTabStyle" it will select style based on current theme of your application
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<Button
android:id="#+id/btnThemeOne"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="Theme One" />
<Button
android:id="#+id/btnThemeTwo"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="Theme Two" />
<Button
android:id="#+id/btnThemeThree"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="Theme Three" />
</LinearLayout>
<android.support.design.widget.TabLayout
android:id="#+id/tabs"
style="?myTabStyle"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:tabGravity="fill"
android:background="#color/colorAccent"
app:tabMode="fixed" />
<android.support.v4.view.ViewPager
android:id="#+id/viewpager"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior" />
</LinearLayout>

PrefManager class to save theme info
import android.content.Context;
import android.content.SharedPreferences;
public class PrefManager {
// Shared preferences file name
private final String PREF_NAME = "theme-pref";
private final String THEME = "theme";
SharedPreferences pref;
SharedPreferences.Editor editor;
public PrefManager(Context context) {
pref = context.getSharedPreferences(PREF_NAME, 0);
editor = pref.edit();
}
public int getTheme() {
return pref.getInt(THEME, R.style.AppTheme);
}
public void setTheme(int themeId) {
editor.putInt(THEME, themeId);
editor.commit();
}
}
you can check the output video of above code

You can find that name in Android theme -
<item name="android:tabWidgetStyle">#style/Your.Style</item>
<style name="Base.Widget.Design.TabLayout" parent="">
<item name="tabSelectedTextColor">#android:color/white</item>
<item name="tabTextColor">#android:color/white</item>
</style>
<style name="Free" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="colorPrimary">#color/black</item>
<item name="colorPrimaryDark">#color/black</item>
<item name="colorAccent">#color/main_red</item>
<item name="android:windowBackground">#color/main_bg_light</item>
<item name="android:listViewStyle">#style/MyListView</item>
<item name="android:tabWidgetStyle">#style/Base.Widget.Design.TabLayout</item>
</style>

Here is my Log:
04-06 12:00:55.860: E/AndroidRuntime(23504): Caused by: java.lang.NullPointerException

Your java code is not complete...there is no include of ActionBar.
So you need an actionBar declared with the methods :
#Override
public boolean onCreateOptionsMenu(Menu menu) {
//Create menu display from the layout XML file menu_main.xml
MenuInflater inflater = getMenuInflater();
inflater.inflate( R.menu.menu , menu );
//Get actionbar as object
ActionBar actionbar = getSupportActionBar();
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
//define action bar action here
return true;
}
Then if you are using android.support.v7.app.ActionBar, you need to change the include
import com.manuelpeinado.fadingactionbar.FadingActionBarHelper;
by
import com.manuelpeinado.fadingactionbar.extras.actionbarcompat.FadingActionBarHelper;
