Android Tutorial - UI TextView

 Add TextView to LinearLayout

    


<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
<TextView  
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:text="@string/directions"
    />
</LinearLayout>

Using ScrollView to hold a TextView

    


package app.Test;

import android.app.Activity;
import android.os.Bundle;
import android.view.KeyEvent;
import android.view.View;
import android.view.View.OnKeyListener;
import android.widget.TextView;

public class appTest extends Activity {

  private TextView urlText;

  @Override
  public void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    urlText = (TextView) findViewById(R.id.text);
    urlText.setOnKeyListener(new OnKeyListener() {
      public boolean onKey(View view, int keyCode, KeyEvent event) {
        if (keyCode == KeyEvent.KEYCODE_ENTER) {
        
          return true;
        }
        return false;
      }
    });

  }
}

//main.xml

<?xml version="1.0" encoding="utf-8"?>
<ScrollView
   xmlns:android="http://schemas.android.com/apk/res/android"
   android:layout_width="fill_parent"
   android:layout_height="fill_parent">
   <TextView
      android:id="@+id/text"
      android:layout_width="fill_parent"
      android:layout_height="wrap_content" />
</ScrollView>

<Button
  android:id="@+id/launchmap"
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content"
    android:text="Show Map"
    /> 
<TextView  
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content"

</LinearLayout>

Set text for TextView

    

package app.test;

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

public class Test extends Activity {
  @Override
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    TextView tv = new TextView(this);
    tv.setText("5! = " + factorial(5));
    setContentView(tv);
  }

  public static long factorial(long n) {
    if (n <= 0)
      return 1;
    else
      return n * factorial(n - 1);
  }
}
