I am trying to change the background color of my SearchView using both xml and code but none seems to be working.
XML:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<SearchView
android:id="#+id/searchView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#ffffff">
</SearchView>
</LinearLayout>
Code:
#InjectView(R.id.searchView) private SearchView searchView;
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
searchView.setBackgroundColor(Color.WHITE);
}
Why are these not working and how can I solve the problem?
Add -
searchView.setBackgroundColor(Color.WHITE);
Did you connect the XML file to the activity?
For instance -
setContentView(R.layout.**YOURXMLHERE**);

I am trying to switch between two WebViews in my layout with Android Java. The two WebViews load different urls when the oncreate method is called. The only problem am having is that the first webview shows up with the site content when oncreate is called but when I click the button that is supposed to show the next webview, it removes the current webview from view and then shows white screen. Help me resolve that, below is my layout file and the android java code behind file
<?xml version="1.0" encoding="utf-8"?>
<ScrollView

android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<ViewSwitcher
android:layout_height="wrap_content"
android:id="#+id/viewSwitcher1"
android:layout_width="wrap_content">
<LinearLayout

and Android Java code for the behavior

if (viewSwitcher.CurrentView != view1)
{
viewSwitcher.ShowPrevious();
}else if(viewSwitcher.CurrentView != view2)
{
viewSwitcher.ShowNext();
}
}
}
I just included an options menu in my app, but in one of my activities it seems to create a white empty space- can anyone tell me why??
It work in other activities in the same app, but not this single activity.
I Hope anyone can help :-)
public class GifsActivity extends OptionsMenu {
private Toolbar toolbar;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_gifs);
toolbar = findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
ImageView gifImageView = (ImageView) findViewById(R.id.iv_gif);
Glide.with(this)
.load("http://i.imgur.com/Vth6CBz.gif")
.asBitmap()
.placeholder(R.drawable.ic_cloud_off_red)
.error(R.drawable.ic_cloud_off_red)
.into(gifImageView);
}
}
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:tools="http://schemas.android.com/tools"
android:gravity="center_vertical"
android:orientation="vertical"
tools:context="com.example.examand1.GifsActivity">
<include layout="#layout/toolbar_layout"

<ImageView

android:layout_width="match_parent"

Remove android:gravity="center_vertical" from your layout. Then your layout will be as below:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<include
android:id="#+id/include"
layout="#layout/toolbar_layout"
android:layout_height="wrap_content"
android:layout_width="match_parent"/>
<ImageView
android:layout_below="#id/include"
android:id="#+id/iv_gif"
android:layout_width="match_parent"
android:layout_height="220dp" />
</RelativeLayout>

I want to make an empty gridview like the image above. I created grid view in xml:
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:custom="http://schemas.android.com/apk/res-auto"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#FFFFFF"
android:orientation="vertical" >
<GridView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/gridview"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:columnWidth="90dp"
android:numColumns="90"
android:verticalSpacing="10dp"
android:horizontalSpacing="10dp"
android:stretchMode="columnWidth"
android:gravity="center"
android:background="#000"
/>
</FrameLayout>
Then I created grid view object in my activity
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_painting);
GridView gridView = (GridView) findViewById(R.id.gridview);
}
But I can't see the borders. Also I can't see any cell and can't click as expected.
How can I create a grid view with empty cells, also with borders.
Thanks in advance.
I'm tring to make a Navigation Drawer using Design Support Library. In my activity_main i wrote this code.
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout
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:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">
<LinearLayout
android:id="#+id/layout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<include
android:id="#+id/toolbar"
layout="#layout/toolbar"/>
<FrameLayout
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</LinearLayout>
<android.support.design.widget.NavigationView
android:id="#+id/navigation_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
app:headerLayout="#layout/header_layout"
app:menu="#menu/menu_drawer"/>
</android.support.v4.widget.DrawerLayout>
When i run my application it works and show the Navigation Drawer but it's below the Status Bar and not above. How can i move it to stay above the StatusBar?
Simply adding android:fitsSystemWindows="false" to DrawerLayout will solve the problem.
Make your activity as full screen to overcome status bar as below or any other method as available on WWW: but it's not good to have drawer over status bar.
public class ActivityName extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// remove title
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.main);
}
}
use this on navigation view xml :
app:insetForeground="#ffffff"
I am trying to hide certain elements in a layout when Android goes out of focus, such that when viewed in the "View recent applications" display, the layout elements will not be visible. Upon selecting the application and going into focus, these elements will be visible again.
My implementation below attempts to show the "content" layout when the application is in focus, and show the "overlay" layout when out of focus, via onWindowFocusChanged().
activity_main.xml
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">
<RelativeLayout
android:id="#+id/content"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="This is the content page"/>
</RelativeLayout>
<RelativeLayout
android:id="#+id/overlay"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="This is the overlay"/>
</RelativeLayout>
</FrameLayout>
MainActivity.java
public class MainActivity extends ActionBarActivity {
FrameLayout layoutContainer;
RelativeLayout layoutContent;
RelativeLayout layoutOverlay;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
layoutContainer = (FrameLayout) findViewById(R.id.container);
layoutContent = (RelativeLayout) findViewById(R.id.content);
layoutOverlay = (RelativeLayout) findViewById(R.id.overlay);
}
#Override
public void onWindowFocusChanged(boolean hasFocus) {
if (hasFocus) {
layoutContent.setVisibility(View.VISIBLE);
layoutOverlay.setVisibility(View.GONE);
} else {
layoutOverlay.setVisibility(View.VISIBLE);
layoutContent.setVisibility(View.GONE);
}
}
}
enter code here
However, my implementation does not work. Anyone with any suggestion as to solve this? Thanks!
If you want to hide views in your layout in recent apps try like this
getWindow().setFlags(WindowManager.LayoutParams.FLAG_SECURE,WindowManager.LayoutParams.FLAG_SECURE);
