title: EditText - keyboard doesn't appear on focus
body: <p>I have this annoying problem.
  My app has 2 activities (tabs) Activity1:listview, Activity2:editText+listview.
  App starts with Tab1(Activity1). When i open 2nd Activity (with edittext), no matter if EditText is selected or not (programmable), when i click on EditText, nothing happens (softKeyboard should appear).
  Only solution is to change activity (click on Tab1 widget) and return to activity 2 - after this tab swap, keyboard works fine.</p>
  
  <p>Part of XML layout with edittext:</p>
  
  <pre><code>    &lt;EditText
      android:hint="Wyszukaj..."
      android:id="@+id/editText1"
      android:layout_width="match_parent"
      android:layout_height="45dp"
      android:inputType="textAutoComplete|text"
      android:singleLine="true" 
      android:focusable="true"
      android:focusableInTouchMode="true"
  &gt;
  </code></pre>
  
  <p>and here is 2 overrided method from Activity2</p>
  
  <pre><code>@Override
  protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.tab2);
  
      this.db = DataBase.getInstance();
      this.ds = DataSource.getInstance();
      this.prepareListView();
  }
  
  @Override
  protected void onResume() {
      super.onResume();
      this.doubleBackToExitPressedOnce = false;
  }
  private void prepareListView() {
      sbal = this.db.getAllStops();
      adapter = new StopListAdapter(this, sbal);
  
      lv = (ListView) findViewById(R.id.tab2list);
      lv.setAdapter(adapter);
      lv.setOnItemClickListener(onClick);
      EditText et = (EditText) findViewById(R.id.editText1);
      et.addTextChangedListener(changeWatcher);
      registerForContextMenu(lv);
  }
  </code></pre>
  
  <p>Do you have any ideas, how XMLcode and activity code should look like in this case?</p>
