In every android phone, we have feature to take screenshots of screens. In this article, we are going to explain how to take screenshots programmatically. A sample GIF is given below to get an idea about what we are going to do in this article. Note that we are going to implement this project using the Java language.
Step by Step Implementation
Step 1: Create a New Project
To create a new project in Android Studio please refer to How to Create/Start a New Project in Android Studio. Note that select Java as the programming language.
Step 2: Add permission to the AndroidManifest.xml file
Add the following permissions to the AndroidManifest.xml file
<uses-permission android:name=”android.permission.READ_EXTERNAL_STORAGE”/>
<uses-permission android:name=”android.permission.WRITE_EXTERNAL_STORAGE”/>
Step 3: Working with the activity_main.xml file
Navigate to the app > res > layout > activity_main.xml and add the below code to that file. Below is the code for the activity_main.xml file.
XML
<?xml version="1.0" encoding="utf-8"?><LinearLayout android:layout_width="match_parent" android:layout_height="match_parent" android:gravity="center" android:orientation="vertical" tools:context=".MainActivity"> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Click on button to take screenshot" android:textColor="#000" android:textSize="20dp" android:textStyle="bold" /> <Button android:id="@+id/clickme" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginTop="10dp" android:background="@color/colorPrimary" android:text="Click Me" /> </LinearLayout> |
Step 4: Add an audio file to the Raw folder
Please refer to the Resource Raw Folder in Android Studio and add an audio file to the Raw folder.
Step 5: Working with the MainActivity.java file
Go to the MainActivity.java file and refer to the following code. Below is the code for the MainActivity.java file. Comments are added inside the code to understand the code in more detail.
