POScreen refusing to refresh after action

copied!<p>I am new to java and currently working on a project. I am trying to get familiar with the bluetooth. So far, i have been able to turn on and off bluetooth from within the app. The problem i have is that the screen does not refresh after an action has been carried out. For example, when i turn on the bluetooth, it comes on, but the text in the textview doesn't update until i flip the phone over. Same for when i disconnect. Here is my code</p> <pre><code>package com.example.bluetooth; import android.os.Bundle; import android.app.Activity; import android.bluetooth.BluetoothAdapter; import android.view.Menu; import android.view.View; import android.widget.Button; import android.widget.TextView; public class MainActivity extends Activity { BluetoothAdapter btAdapter = BluetoothAdapter.getDefaultAdapter(); Button button; TextView update; CharSequence enabled = "Bluetooth Enabled"; CharSequence disabled = "Bluetooth disabled"; CharSequence connect = "Connect"; CharSequence disconnect = "Disconnect"; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); setUp(); action(); } private void action() { if (button.getText() == connect) { button.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { btAdapter.enable(); } }); } if (button.getText() == disconnect) { button.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { btAdapter.disable(); } }); } } private void setUp() { button = (Button) findViewById(R.id.button1); update = (TextView) findViewById(R.id.textView1); button = (Button) findViewById(R.id.button1); if (btAdapter.isEnabled()) { update.setText("Bluetooth is enabled"); button.setText(disconnect); } else { update.setText("Bluetooth is disabled"); button.setText(connect); } } @Override public boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu; this adds items to the action bar if it is present. getMenuInflater().inflate(R.menu.activity_main, menu); return true; } } </code></pre> <p>Any help at all would be appreciated. Thank you.</p>
