Switch statement with numbers and array of strings Java example.

public class MainClass {
	public static void main(String[] arg) {
		String[] arrayOfString = { "One", "Two", "Three", "Four" };

		int i = 2;
		switch (i) {
			case 1: {
				System.out.println(arrayOfString[i]);
				break;
			}
			case 2: {
				System.out.println(arrayOfString[i]);
				break;
			}
			case 3: {
				System.out.println(arrayOfString[i]);
				break;
			}
			default: {
				System.out.println("Enter a valid value.");
			}
		} // END of switch
	}
}
/*
 * Three
 */

Possible:

case 1:
 System.out.println(arrayOfString[i]);
break;

// i love this notation 
case 1:{
 System.out.println(arrayOfString[i]);
}break;

case 1:{
 System.out.println(arrayOfString[i]);
 break;
}

xml RelativeLayout Android example:

Eclipse graphical xml layout editor
[caption id="attachment_896" align="alignleft" width="261" caption="Relativelayout Eclipse graphical editor"][/caption]

Warning: The application may be doing too much work on its main thread
Try this sorce code:

import android.os.StrictMode;

public class MyActivity extends Activity {
	static{
		StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
		StrictMode.setThreadPolicy(policy);
	}
	@Override
    public void onCreate(Bundle savedInstanceState) {
//.................. etc.

StringBuilder, res/raw folder, try catch finaly throws, BufferedReader, InputStream, openRawResource, getResources Android example

MainActivity.java

public class MainActivity extends Activity {
TextView txtV;
	Context cntx;
	
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        txtV = (TextView)findViewById(R.id.idLabel);
        cntx = this;
        try {
			StringBuilder strBuilder = myFunction(cntx);
			txtV.setText(strBuilder);
		} catch (IOException e) {
			e.printStackTrace();
		}

        
    }
    
    
    private StringBuilder myFunction(Context context) throws IOException {
        final Resources resources =  context.getResources();
        InputStream inputStream = resources.openRawResource(R.raw.my_file);
        BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));
        StringBuilder strBuild = new StringBuilder();
        try {
            String line;
            while ((line = reader.readLine()) != null) {
            	strBuild.append(line);
            }
        } finally {
            reader.close();
        }
       return strBuild; 
       
    }
