Android :: Change Text View At Run Time

Sep 16, 2010

i“m working with a lineal layout and I“m trying to change the text of a TextView but it doesn“t refresh. When I debug I“ve checked that the text have changed correctly.public class Position extends Activity {
Button botonempezar;
Button botonsalir;
TextView text;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.position);
botonsalir = (Button) findViewById(R.id.salir);
botonempezar = (Button) findViewById(R.id.Empezar);
text = (TextView) findViewById(R.id.Textoposicion);
botonsalir.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
onDestroy();
finish();
} botonempezar.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
searchPosition();
private void searchPosition(){
boolean condition = true;
do{
determinatePosition();
}while(condition == true);
private void determinatePosition(){
this.text.setText("New text");
//this.text.invalidate();
this.text.postInvalidate();
Toast.makeText(getBaseContext(), "New text", Toast.LENGTH_SHORT);// this doesnt work neither.
Here I post the code of the xml file. Its really silly but it could be the problem:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TextView
android:layout_height="wrap_content"
android:id="@+id/Textoposicion"
android:text="PosiciĆ³n desconocida"
android:layout_width="fill_parent"
android:layout_marginTop="20dip"
android:inputType="text">
</TextView>
<Button android:layout_height="wrap_content"
android:id="@+id/Empezar" android:text="Empezar"
android:layout_width="fill_parent"
android:layout_marginTop="20dip">
</Button>
<Button
android:layout_height="wrap_content"
android:id="@+id/salir"
android:layout_marginTop="20dip"
android:text="Finalizar programa"
android:gravity="center" android:layout_width="fill_parent">
</Button></LinearLayout>
I have edited the post because I omitted part of the code to make it simpler but I think I may suppressed the problem too. It runs in a endless loop, could be this the mistake?

Android :: Multi Column Custom List View / With Editable Edit Text At End Of List View

Nov 3, 2010

I am on Android 2.1 and I have one multi column Custom listview Using BaseAdapter with an editable edittext at the end of the listview. If the data in the listview do not contain the data of user choice then user should be able to enter data. If the data is already there in the list user will be able to select the data using custom selector. If a selection is made in the list view and user wanted to enter data in the text field at the bottom after selection then the marker in the list view should be unselected. I tried to use onclick() method on edit text using click listener. First time when it is clicked, edit text is getting focus and onclick() method is not fired. And when it is clicked second time, onclick() method is fired and notifyDataSetChanged() method is called. I tried to call the notifyDataSetChanged() method from the Focus Listener, list view selection is gone in my first attempt and edit text is not receiving any data input from the keyboard (frozen).

Android :: Text View With AutoLink

Feb 19, 2009

My app implements a ListView in which every row contains a TextView which has the autoLink property turned on. The links are properly displayed when emails, phone numbers and web links are present in the text. The problem I have is that long presses don't work as they would if the no links would be detected in the text message. Specifically the selection rectangle (the one that becomes progressively whiter as long as the list item is pressed) does not appear at all. It looks like when links are present in the text the touch events are consumed by the links.

Android :: Using Class Derived From Text / View

Jun 19, 2010

CoreStartHere.java
public class CoreStartHere extends TabActivity {
t = getTabHost();
t.newTabSpec("tTask");
t.setIndicator(...);
t.setContent(new Intent().setClass(this, T1Task.class);
} t1Task.java
T1Task extends Activity {
onCreate(Bundle ...) {
:
myListview = (ListView) findViewById(R.id.hdListView);
myEditText = (EditText) findViewById(R.id.hdEditText);
hdItems = newArrayList <String>();
aa = new ArrayAdapter <String>(this, R.layout.hditemview, hdItems);
:
setOnKeyListener (new OnKeyListener() {
onKey(...) {
:
hdItems.add(0, myEditText.getText().toString());
aa.notifyDatasetChanged();

hditemview.xml
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
class="com.a1.hd.hdRecordTaskListItemView"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="10dp"
android:scrollbars="vertical"
android:textColor="@color/HD_Text"
android:fadingEdge="vertical"
/>hdRecordTaskListItemView.java
hdRecordTaskListItemView extends TextView {
// has 3 constructors
// onDraw
}
None of the constructor in hdRecordTaskListItemView get invoked and not surprisingly onDraw does not get called either. The text appears with the default style. The onDraw is supposed to draw on the "canvas".
