In this article, we are going to implement a very important feature related to TextView. While using any social media app or like using Facebook you may have seen there is a particular type of TextView which you cannot copy like a caption that people write on their posts. You can select the message but there few texts which cannot select or copy. So here we are going to learn how to implement that feature.
Implementing this feature for TextView
Method 1
Step 1: 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:padding="20dp" android:gravity="center" android:orientation="vertical" tools:context=".SelectText"> <TextView android:id="@+id/select" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Geeks For Geeks " android:layout_alignParentTop="true" android:layout_centerHorizontal="true" android:textSize="30dp" /> </LinearLayout> |
Step 2: Working with the MainActivity.java file
This is something that enables our text to be get selected and then we can copy that text
select.setTextIsSelectable(true);
This disables our text to be get selected or even by default it is set as false. Hence you cannot select a text in default mode
select.setTextIsSelectable(false);
Go to the MainActivity.java file and refer to the following code. Below is the code for the MainActivity.java file.
Java
import androidx.appcompat.app.AppCompatActivity;import androidx.core.app.ActivityCompat;import androidx.core.content.ContextCompat; import android.Manifest;import android.content.pm.PackageManager;import android.os.Bundle;import android.telephony.SmsManager;import android.view.View;import android.widget.Button;import android.widget.CheckBox;import android.widget.EditText;import android.widget.TextView;import android.widget.Toast; import org.w3c.dom.Text; public class SelectText extends AppCompatActivity { TextView select; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_select_text); select = findViewById(R.id.select); select.setTextIsSelectable(true); }} |
Method 2
Make Changes in the XML file. Add this line in your TextView.
android:textIsSelectable="true"
XML
<?xml version="1.0" encoding="utf-8"?><LinearLayout android:layout_width="match_parent" android:layout_height="match_parent" android:padding="20dp" android:gravity="center" android:orientation="vertical" tools:context=".SelectText"> <TextView android:id="@+id/select" android:layout_width="wrap_content" android:layout_height="wrap_content" android:textIsSelectable="true" android:text="Geeks For Geeks " android:layout_alignParentTop="true" android:layout_centerHorizontal="true" android:textSize="30dp" /> </LinearLayout> |
Output:
Implementing this feature for EditText
Step 1: 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. We will create a simple EditText.
XML
<?xml version="1.0" encoding="utf-8"?><LinearLayout android:layout_width="match_parent" android:layout_height="match_parent" android:padding="20dp" android:gravity="center" android:orientation="vertical" tools:context=".SelectText"> <EditText android:id="@+id/selecte" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_alignParentTop="true" android:layout_centerHorizontal="true" android:cursorVisible="false" android:textSize="30dp" /> </LinearLayout> |
Step 2: 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. In EditText By default, we can select text. Here firstly we will hide the cursor in the layout.xml file
android:cursorVisible="false"
And added an eventlistener for long click and display the cursor only when a selection starts.
selecte.setCursorVisible(true);
Java
import androidx.appcompat.app.AppCompatActivity;import androidx.core.app.ActivityCompat;import androidx.core.content.ContextCompat; import android.Manifest;import android.content.pm.PackageManager;import android.os.Bundle;import android.telephony.SmsManager;import android.view.View;import android.widget.Button;import android.widget.CheckBox;import android.widget.EditText;import android.widget.TextView;import android.widget.Toast; import org.w3c.dom.Text; public class SelectText extends AppCompatActivity { EditText selecte; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_select_text); selecte = findViewById(R.id.selecte); selecte.setOnLongClickListener(new View.OnLongClickListener() { @Override public boolean onLongClick(View v) { selecte.setCursorVisible(true); Toast.makeText(SelectText.this,"Visible",Toast.LENGTH_LONG).show(); return false; } }); }} |
Output:
