Android SDK m5-rc14 Released

New Android SDK released. There are some improvement, and changes. And some of my samples, i publish here and at learncodes.googlepages.com maybe have function that has been changed. But i think you the reader will be easily adopted.

Some of them, like there isn't onMotionEvent (MotionEvent ev) method but has been changed to OnTouchEvent(MotionEvent ev), there should be android:name on AndroidManifest.xml not id, but id, still can be use with warning.

So, hope you, the reader, will adopt it easily.

Changing TextView to receive user input programatically

TextView is the ancestor of EditText component. I've try to make TextView from XML design screen to receive input from user still is unsuccessful. But Programatically, i can change the TextView able to receive user input.

To do this, just create activity folder with activitycreator and modify the main activity class, say we have Sample Class below:

public class SampleTextView extends Activity
{
/** Called with the activity is first created. */
@Override
public void onCreate(Bundle icicle)
{
super.onCreate(icicle);
LayoutParams params = new LayoutParams(
LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT);
TextView v = new TextView(this);
v.setLayoutParams(params);
v.setInputMethod(TextInputMethod.getInstance());
v.setMovementMethod(ArrowKeyMovementMethod.getInstance());
v.setFocusable(true);
v.setText("TEST");
v.setBackgroundColor(0x88FFFF00);
setContentView(v, params);

}
}

Things you have to note is :

1. Set the TextView to receive focus ( setFocusable )
   
2. Set the Input Method to know how method will be used ( setInputMethod )
   
3. Set the Movement Method to know how to handle cursor pointer ( setMovementMethod )
   

Compile and run the program, you can edit the content of TextView.
Good Luck !
