The following example shows a simple method to make an activity transparent in android.
For this first create a fresh project and copy this java code into it.
package pack.coderzheaven;import android.app.Activity;import android.os.Bundle;public class TranslucentActivity extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); }} |
Now the main layout file main.xml
<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" ><TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="@string/hello" android:textColor="@drawable/red" android:textStyle="bold" /><Button android:text="This is Translucent Activity Demo From CoderzHeaven" android:id="@+id/Button01" android:layout_width="wrap_content" android:layout_height="wrap_content" android:textColor="@drawable/red" android:textStyle="bold"></Button></LinearLayout> |
OK Now here is the style that has to be applied to make the activity transparent.
create a file named style.xml inside res/values folder and copy this code into it.
<?xml version="1.0" encoding="utf-8"?><resources> <style name="Theme.Transparent" parent="android:Theme"> <item name="android:windowIsTranslucent">true</item> <item name="android:windowBackground">@android:color/transparent</item> <item name="android:windowContentOverlay">@null</item> <item name="android:windowNoTitle">true</item> <item name="android:windowIsFloating">true</item> <item name="android:backgroundDimEnabled">false</item> </style></resources> |
Now where to apply this theme. It is applied in the AndroidManifest.xml
This file is shown below.
<?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="http://schemas.android.com/apk/res/android" package="pack.coderzheaven" android:versionCode="1" android:versionName="1.0"> <application android:icon="@drawable/icon" android:label="@string/app_name"> <activity android:name=".TranslucentActivity" android:theme="@style/Theme.Transparent" 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></manifest> |
Check this line in the manifest where this style is applied.
android:theme=”@style/Theme.Transparent”
The appname and different colors are in the strings.xml
<?xml version="1.0" encoding="utf-8"?><resources> <string name="hello">TranslucentActivity! From Coderzheaven</string> <string name="app_name">TranslucentActivity</string> <drawable name="white">#ffffff</drawable> <drawable name="black">#000000</drawable> <drawable name="blue">#2554C7</drawable> <drawable name="green">#347C2C</drawable> <drawable name="orange">#ff9900</drawable> <drawable name="pink">#FF00FF</drawable> <drawable name="violet">#a020f0</drawable> <drawable name="grey">#778899</drawable> <drawable name="red">#C11B17</drawable> <drawable name="yellow">#FFFF8C</drawable> <drawable name="PowderBlue">#b0e0e6</drawable> <drawable name="brown">#2F1700</drawable> <drawable name="Hotpink">#7D2252</drawable> <string name="select_Category">Select Category</string> <drawable name="darkgrey">#606060</drawable></resources> |
