    <p>Just studying Threads in Android (I'm also a little new to Threads period). I'm looking at various other posts but still need a little clarification. I'm keeping it simple with HelloWorld. What I want to is display the Message: "Hello World this is a thread" with each word displayed at 1 second intervals. Thought use a string array with the message. Then use a for loop in the thread to iterate through each element. I'm pretty sure I understand the logic of my problem - in that the whole loop executes in the delay time frame. Can anyone tell me how I can break this out so I can display each element at 1 second intervals? Here is my code:</p> <pre><code>public class HelloWorld extends Activity { Handler m_handler; Runnable m_handlerTask ; private TextView hello; private String[] HelloWorld = { "Hello", "World", "This", "Is", "A", "Thread", }; int i=0; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_hello_world); hello = (TextView) findViewById(R.id.hello); m_handler = new Handler(); m_handlerTask = new Runnable() { @Override public void run() { if(i&lt;HelloWorld.length-1) { hello.append(HelloWorld[i]); hello.setText("\n"); i++; } m_handler.postDelayed(m_handlerTask, 1000); } }; m_handlerTask.run(); m_handler.removeCallbacks(m_handlerTask); } @Override public boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu; this adds items to the action bar if it is present. getMenuInflater().inflate(R.menu.hello_world, menu); return true; } </code></pre> <p>}</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
