MainActivity.java
I've implemented MultiChoiceModeListener in this class and below is the code:
on listView:
listView.setMultiChoiceModeListener(MainActivity.this);
listView.setChoiceMode(listView.CHOICE_MODE_MULTIPLE_MODAL);
#Override
public boolean onActionItemClicked(ActionMode arg0, MenuItem arg1) {
switch (arg1.getItemId()) {
case R.id.save:
// Close CAB
arg0.finish();
return true;
case R.id.saveto:
// Close CAB
arg0.finish();
return true;
default:
return false;
}
}
#Override
public boolean onCreateActionMode(ActionMode arg0, Menu arg1) {
arg0.getMenuInflater().inflate(R.menu.save_menu, arg1);
return true;
}
#Override
public void onDestroyActionMode(ActionMode arg0) {
listadaptor.removeSelection();
}
#Override
public boolean onPrepareActionMode(ActionMode arg0, Menu arg1) {
return false;
}
#Override
public void onItemCheckedStateChanged(ActionMode arg0, int arg1, long arg2,
boolean arg3) {
final int checkedCount = listView.getCheckedItemCount();
arg0.setTitle(checkedCount + " "+getResources().getString(R.string.selected));
listadaptor.toggleSelection(arg1);
}

below is my screenshots:
you can see both screenshots, in second screenshot, actionmode background is white and text color is also white.. i want to change it to first screenshots color which is in top.
You can change the ActionMode background through attribute actionModeStyle:
<style name="AppTheme.Base" parent="Theme.AppCompat.Light">
....
....
<item name="actionModeStyle">#style/LStyled.ActionMode</item>
</style>
<style name="LStyled.ActionMode" parent="#style/Widget.AppCompat.ActionMode">
<item name="background">#color/color_action_mode_bg</item>
</style>
You will of course need to define a color named color_action_mode_bg:
<color name="color_action_mode_bg">#009688</color>
There are other things you can change as well. Example:
<item name="titleTextStyle">...</item>
<item name="subtitleTextStyle">...</item>
<item name="height">...</item>
To change text color of SAVE and SAVETO, add the following to AppTheme.Base:
<item name="actionMenuTextColor">#color/color_action_mode_text</item>
use actionModeBackground in your AppTheme.Base style.
<item name="actionModeBackground">#color/colorPrimary </item> (or)
<item name="android:actionModeBackground">#color/colorPrimary </item>
To change the Title Color of contextual action bar this was the only method that worked for me:
Write this in your activity's theme
<item name="actionModeStyle">#style/ContextualActionModeTheme</item>
Define the styles
<style name="ContextualActionModeTheme" parent="#style/Widget.AppCompat.ActionMode">
<item name="titleTextStyle">#style/titleColor</item>
</style>
<style name="titleColor" parent="TextAppearance.AppCompat.Widget.ActionMode.Title">
<item name="android:textColor">#color/your_color_here</item>
</style>
The title color of your contextual action bar would be changed.

I want to make my Contextual Action Bar show a close icon other than the back arrow, but I'm not succeeding.
To do this, I have changed the actionModeCloseDrawable property in my styles.xml file: <item name="actionModeCloseDrawable">#drawable/ic_baseline_close_24</item>, but it is not working, as you can see in the image below:
This is my code at styles.xml:

How it's not working?
If I try this:
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if (item.getItemId() == R.id.item_voz) {
if (mActionMode == null) {
//mActionMode = getActivity().startActionMode(mActionModeCallback);
mActionMode = ((AppCompatActivity)getActivity()).startSupportActionMode((androidx.appcompat.view.ActionMode.Callback) mActionModeCallback);
}
getActivity().invalidateOptionsMenu();
return true;
}
I'm having this error:

How about using a Toolbar? androidx.appcompat.widget.Toolbar has this method:
public void setNavigationIcon(#DrawableRes int resId)
Maybe activity.actionBar.setHomeAsUpIndicator(R.id.back)
How to change the App theme dynamically in android. I have an app with many users, when users log in, as per requirements I have to change the app theme dynamically.
Try this
styles.xml

<item name="overlapAnchor">false</item>
<item name="android:popupBackground">#color/blue_grey</item>
<item name="android:textColor">#color/white</item>
</style>
create this in BaseActivity and call in onCreate method
public void updateTheme()
{
if (Utility.getTheme(getApplicationContext()))
{
setTheme(R.style.darkTheme);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
}
else
{
setTheme(R.style.lightTheme);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
}
}
Utility.java
public static void setTheme(Context context, boolean theme)
{
SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(context);
prefs.edit().putBoolean(context.getString(R.string.prefs_theme_key), theme).apply();
}
public static Boolean getTheme(Context context)
{
SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(context);
return prefs.getBoolean(context.getString(R.string.prefs_theme_key), false);
}
and in any Activity use any component to change theme, in this case Switch
Switch darkModeSwitch = findViewById(R.id.darkModeSwitch);
darkModeSwitch.setChecked(Utility.getTheme(this));
darkModeSwitch.setOnCheckedChangeListener((compoundButton, checked) ->
{
Utility.setTheme(getApplicationContext(), checked);
});
I am developing an android application. I want to add night mode and day mode in app. I want to make it visible in app's actionbar.
Currently my style.xml file is
<style name="Theme.FullScreen" parent="#android:style/Theme.Black.NoTitleBar.Fullscreen"></style>
<style name="PreferencesTheme" parent="android:Theme.Light">
<item name="android:background">#FFEAEAEA</item>
</style>
<style name="PreferencesTheme" parent="android:Theme.Light">
<item name="android:windowBackground">#drawable/ic_icon_settings</item>
</style>
I solved this problem by using this in my xml file :
<style name="ActionBar" parent="#android:style/Widget.Holo.ActionBar" />
<style name="ActionBar.Light" parent="#style/ActionBar">
<item name="android:background">#color/actionbar_background_light</item>
</style>
<style name="ActionBar.Dark" parent="#style/ActionBar">
<item name="android:background">#color/actionbar_background_dark</item>
</style>
<style name="AppTheme.Light" parent="#android:style/Theme.Holo.Light">
<item name="android:actionBarStyle">#style/ActionBar.Light</item>
<item name="android:windowActionBarOverlay">true</item>
<item name="listDragShadowBackground">#android:color/background_light</item>
<item name="menuIconCamera">#drawable/ic_menu_camera_holo_light</item>
<item name="menuIconToggle">#drawable/ic_menu_toggle_holo_light</item>
<item name="menuIconShare">#drawable/ic_menu_share_holo_light</item>
</style>
<style name="AppTheme.Dark" parent="#android:style/Theme.Holo">
<item name="android:actionBarStyle">#style/ActionBar.Dark</item>
<item name="android:windowActionBarOverlay">true</item>
<item name="listDragShadowBackground">#android:color/background_dark</item>
<item name="menuIconCamera">#drawable/ic_menu_camera_holo_dark</item>

<item name="menuIconShare">#drawable/ic_menu_share_holo_dark</item>

MENUS TO SWITCH BETWEEN THE MODES
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.toggleTheme:
if (mThemeId == R.style.AppTheme_Dark) {
mThemeId = R.style.AppTheme_Light;
} else {
mThemeId = R.style.AppTheme_Dark;
}
this.recreate();
return true;
default:
return super.onOptionsItemSelected(item);
}
}
The Global Variable necessary for switching between the modes:
private int mThemeId = -1;
And for saving the last selected mode, in the onCreate():
if(savedInstanceState != null && savedInstanceState.getInt("theme", -1) != -1) {
mThemeId = savedInstanceState.getInt("theme");
this.setTheme(mThemeId);
}
I have an AppCompatActivity which contains android.app.Fragment. In fragment I have a button on the toolbar which fires the method showDialog():
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if (item.getItemId() == R.id.action_add_ingredient) {
showDialog();
return true;
}
return super.onOptionsItemSelected(item);
}
private void showDialog() {
// 1. Instantiate an AlertDialog.Builder with its constructor
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
// 2. Chain together various setter methods to set the dialog
// characteristics
builder.setTitle(R.string.dialog_ingredient_add_title);
builder.setView(mActivityMain.getLayoutInflater().inflate(
R.layout.dialog_shopping_ingredient_add, null));
builder.setPositiveButton(R.string.dialog_ingredient_ok,
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
dialog.dismiss();
}
});
builder.setNegativeButton(R.string.dialog_ingredient_cancel,
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
dialog.dismiss();
}
});
// 3. Get the AlertDialog from create()
dialog = builder.create();
dialog.show();
}
As it can be seen from the code, a android.support.v7.app.AlertDialog appears.
Picture 1. AlertDialog shown.
Then I select some text.
Picture 2. Text selected.
And somehow text selection tool shows only half of it and is unclickable.
My styles.xml file is below.

Question:
How can I make the text selection tool fully visible and clickable?
i have an Activity with an Action Bar. The Action Bar PopUp Menu (that appears after clicking the overflow button) applies my defined style.
But there is a EditText View inside my Activity, that should open a popup Menu by clicking on it.
This PopUp does not apply the style.
I hope someone can help me out..
Thx!!
