    <p>simple maybe stupid question. I have a login activity which launches another activity, and here's the code:</p> <pre><code>public class LoginActivity extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.login); ActionBar actionBar = getActionBar(); actionBar.hide(); Button btnLogin = (Button) findViewById(R.id.btnLogin); final TextView tvUsername = (TextView) findViewById(R.id.tvUsername); final TextView tvPassword = (TextView) findViewById(R.id.tvPassword); btnLogin.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { if (tvUsername.getText().toString().length()&lt;1) { Toast msg = Toast.makeText(LoginActivity.this, "Enter a Username", Toast.LENGTH_LONG); msg.setGravity(Gravity.TOP|Gravity.LEFT, 0, 70); msg.show(); tvUsername.requestFocus(); } else if (tvPassword.getText().toString().length()&lt;1) { Toast msg = Toast.makeText(LoginActivity.this, "Enter a Password", Toast.LENGTH_LONG); msg.setGravity(Gravity.TOP|Gravity.LEFT, 0, 200); msg.show(); tvPassword.requestFocus(); } else { startActivity(new Intent(LoginActivity.this,CrewScheduleActivity.class)); finish(); } } }); } } </code></pre> <p>My question is about the textviews. Eclipse basically said i had to make them final in order to use them in the onClick event of the button. NP so i did that and it worked.</p> <p>The question is What is the difference between putting these above the @Override as private vs inside the OnCreate as final?</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.
