Android: TextView automatically truncate and replace last 3 char of String

Android: TextView automatically truncate and replace last 3 char of String

If you want to automatically truncate a TextView and replace the last three characters of a string in Android, you can achieve this by modifying the text before setting it to the TextView. Here's a sample code snippet that demonstrates how to do this:

import android.os.Bundle; import android.widget.TextView; import androidx.appcompat.app.AppCompatActivity; public class MainActivity extends AppCompatActivity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); TextView textView = findViewById(R.id.textView); // Original text String originalText = "This is a sample text"; // Check if the original text has at least 3 characters if (originalText.length() >= 3) { // Truncate the last 3 characters String truncatedText = originalText.substring(0, originalText.length() - 3); // Replace the last 3 characters with "..." truncatedText += "..."; // Set the modified text to the TextView textView.setText(truncatedText); } else { // Handle the case when the original text is too short to truncate textView.setText(originalText); } } }

In this code:

  1. We have a TextView named textView in an Android activity.

  2. We define the originalText string, which is the text you want to display.

  3. We check if the originalText has at least 3 characters. If it does, we truncate the last 3 characters using the substring() method and then append "..." to the truncated text.

  4. Finally, we set the modified text to the TextView. If the original text has fewer than 3 characters, we simply set the original text as is.

You can adapt this code to your specific use case by replacing originalText with the text you want to display in your TextView.
