Android Textview Programmatically

Android Textview Programmatically

Android Textview Programmatically : In my previous post, I explained basics of Android Textview Control. In this post, I’ll explain how you can set properties of a Android textview control programmatically.

In your layout file, make a Textview as below :

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
 xmlns:tools="http://schemas.android.com/tools"
 android:layout_width="match_parent"
 android:layout_height="match_parent"
 android:background="#fff"
 android:orientation="vertical" >

<TextView
 android:id="@+id/txtView1"
 android:layout_width="wrap_content"
 android:layout_height="wrap_content"
 android:layout_gravity="center"
 android:layout_margin="2dp"
 android:padding="5dp" />

</LinearLayout>

Here, my Textview control Id is txtView1. In the code file, we can use this Id to set its property as below :

txtView1.setText("Hello, I'm a simple Android Textview control.");
 txtView1.setTextSize(16);
 txtView1.setTextColor(Color.parseColor("#ff0000"));

Here’s my full java file :

TextActivity.java :

package parallelcodes.simplewidget;

import android.app.Activity;
import android.graphics.Color;
import android.os.Bundle;
import android.widget.TextView;

public class TextActivity extends Activity {
 
 TextView txtView1;
 
 @Override
 protected void onCreate(Bundle savedInstanceState) {
 super.onCreate(savedInstanceState);
 setContentView(R.layout.activity_main);
 
 txtView1 = (TextView) findViewById(R.id.txtView1);
 
 txtView1.setText("Hello, I'm a simple Android Textview control.");
 txtView1.setTextSize(16);
 txtView1.setTextColor(Color.parseColor("#ff0000"));
 
 }


}

This is output of above code :
