There are different ways for making an acitivity transparent.
First method
1. Through XML in AndroidManifest
like this.
<activity android:name="com.coderzheaven.interfacedemo.MainActivity" android:label="@string/app_name" <strong> android:theme="@android:style/Theme.Translucent"</strong> > </activity> |
Here we are using Android’s built in theme.
Method 2
Through styles
create a style like this in your styles.xml
<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> |
and applying like this in the AndroidManifest.xml
<activity android:name="com.coderzheaven.interfacedemo.MainActivity" android:label="@string/app_name" <strong>android:theme="@style/Theme.Transparent"</strong> > </activity> |

Now we see how to make a Dialog transparent.
I am using this post for explaining this
package com.coderzheaven.interfacedemo;import android.app.Activity;import android.graphics.drawable.ColorDrawable;import android.os.Bundle;import android.view.Window;import android.view.WindowManager;import android.widget.Toast;import com.coderzheaven.interfacedemo.MyDialog.myOnClickListener;public class MainActivity extends Activity { public myOnClickListener myListener; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); // create new onclicklistener interface // myListener = new myOnClickListener() { @Override public void onButtonClick() { Toast.makeText(getApplicationContext(), "This is a Transparent Custom Dialog Demo", Toast.LENGTH_LONG).show(); } }; MyDialog mydialog = new MyDialog(this, myListener); mydialog.show(); addTransparency(mydialog); } void addTransparency(MyDialog mydialog) { mydialog.getWindow().setBackgroundDrawable( new ColorDrawable(android.graphics.Color.TRANSPARENT)); }} |
This code does the work here for transparency in the Dialog.
void addTransparency(MyDialog mydialog) { mydialog.getWindow().setBackgroundDrawable( new ColorDrawable(android.graphics.Color.TRANSPARENT)); } |
