Actually, the way android platform does that is by setting the MaxLine to Integer.MAX_VALUE.

    textView.setMaxLines(Integer.MAX_VALUE);

also, if you are using Ellipsize, don&#39;t forget to set to null. 

    textView.setEllipsize(null);

just check how the android framework do just that ;) watch the setMaxLines(Integer.MAX_VALUE); 

    private void applySingleLine(boolean singleLine, boolean applyTransformation) {
    	mSingleLine = singleLine;
    	if (singleLine) {
    		setLines(1);
    		setHorizontallyScrolling(true);
    		if (applyTransformation) {
    			setTransformationMethod(SingleLineTransformationMethod.getInstance());
            }
           } else {
                setMaxLines(Integer.MAX_VALUE);
                setHorizontallyScrolling(false);
                if (applyTransformation) {
                     setTransformationMethod(null);
            }
           }
         }

Try this (**infoView.getLineCount()**):

    public void onMoreClick(View v) {
		Button btn = (Button) v;
		if(!moreSwitcher) {
			infoView.setMaxLines(infoView.getLineCount());
			infoView.setLines(infoView.getLineCount());
			moreSwitcher = true;
			btn.setText(R.string.collapse);
		}else{
			infoView.setMaxLines(5);
			infoView.setLines(5);
			moreSwitcher = false;
			btn.setText(R.string.expand);
		}

I&#39;ve been trying to figure out how the fork-exec mechanism is used inside Linux.  Everything was going on according to the plan until some web pages started to confuse me.

It is said that a child process should strictly use `_exit()` instead of a simple `exit()` or a normal return from `main()`. 

As I know, Linux shell fork-execs every one of the external commands; assuming what I said above is true, the conclusion is that none of these external commands nor any other execution happening inside the Linux shell can do normal return!

Wikipedia &amp; some other webpages claim we&#39;ve got to use `_exit()` just to prevent a child process causing deletion of parent&#39;s temporary files while a probable double flushing of stdio buffers may happen. though I understand the former, I have no clues how a double flushing of buffers could be harmful to a Linux system.

I&#39;ve spent my whole day on this...
Thanks for any clarification.

What is the difference between using _exit() &amp; exit() in a conventional Linux fork-exec?

I&#39;m working on developing a web application with Spring 3 and Hibernate 3.6. At the moment I try to understand how Caching with Spring and Hibernate works. I found some sources about Caching with Hibernate and some about Spring and I try to bring my information together now. I still got some questions to both frameworks and I&#39;d be glad if someone could answer them or tell me if the facts listed here are correct.

Most of the time, short answers (yes/no) would be sufficient. I think that this list can be useful for others too, who want to understand how caching with spring and hibernate works.

`General`

**1)** Hibernate supports the following Caches: 1st Level Cache, 2nd Level Cache, Query Cache

**2)** Spring itself supports the following Caching possibilities: just Method Caching 

`1st Level Cache`

**3)** The 1st Level Cache is part of EVERY Hibernate application. 

**4)** The 1st Level Cache is created for EVERY hibernate-session. 

**5)** What is saved in the 1st Level Cache? Objects or just the values of their properties? queries and their results?

`2nd Level Cache`

**6)** I found out: the 2nd Level Cache is used ONCE per application. isn&#39;t that false? isn&#39;t it used ONCE per `SessionFactory`? and: multiple sessionfactorys = multiple 2nd level caches possible?

**7)** what is saved in the 2nd Level Cache: in my opinion just the values belonging to one record, not the objects itself.

**8)** when storing values from one record in 2nd Level Cache, its possible to store related values (from objects connected over a foreign key) with it too?

**9)** when updating the values of one object in the 2nd level cache, it&#39;s possible to update the values of objects connected with it in the cache too?

**10)** when values of an object are changing, how can I update the 2nd level cache? flush? can I just update a part of the cache or must the whole cache be updated?

**11)** where does the 2nd level cache make sense and where doesn&#39;t it?

**12)** the Cache Mode: does each cache mode provide a different strategy of caching? for example with cache mode &quot;read-only&quot; no synchronization of database and cache is ever necessary? do other cache modes provide synchronization? I thought synchronization must be done by the developer himself?

`Query Cache`

**13)** what is the difference between the Query Cache and the 2nd Level Cache? in my opinion: in the Query Cache result sets are saved, but not with their values, just with their ids. when the query is used again and the result set is still &quot;correct&quot;, the values belonging to the ids are queried from the 2nd Level Cache

**14)** For the Query Cache a 2nd Level Cache MUST be used?

**15)** where does the Query Cache make sense and where doesn&#39;t it?

`Spring`

**16)** Does Spring provide more Caching possibilities than method caching?

**17)** method caching is not linked to hibernate caching

**18)** but: for method caching the 2nd level is necessary, like Ehcache (which can be used by hibernate too)

**19)** can method caching be used without database queries?

`Getting mixed up`

**20)** if using ehcache for hibernate as 2nd level cache and Ehcache for spring for method caching, can I use the same Ehcache-instance? is there a chance that something gets mixed up?

**21)** when using 1st level cache and 2nd level cache, can they get mixed up? when querying the database, where does the result then come from, the 1st or 2nd level cache? does the 1st level cache work with the 2nd level cache?

**22)** anything else that can get mixed up by using the caches I mentioned? :-)

Thanks for answering, no matter what question! :-)

I want to make a TextView that is collapsable by user&#39;s touch.
When the TextView collapsed, I set `textView.setMaxLines(4);`.
How to I clear this state in my expand method?
I can only think of call `setMaxLines()` with a value large number like **10000**.

Are there better ways to implement this?

i want to use a ListView with the items having following layout

    ------------------------- 
     [CB]    TV            TV
    -------------------------

CB is a checkbox and TV is a Textview.

Now i&#39;ve read somewhere that you can&#39;t have clickable items in a ListView. If you have some then you won&#39;t be able to click on the ListItems. 
But if I look at the GoogleMail app, this is possible. I can mark several messages with the checkbox (and then select an action for them) or i can click on the ListItem (or scroll with the dpad) to get to another screen. 
Does someone has code/example how this is possible?

In Android can we store an object of a class in shared preference and retrieve the object later?

If it is possible how to do it? If it is not possible what are the other possibilities of doing it?

What&#39;s the best way to disable the touch events for all the views?


Disable the touch events for all the views

I have a subclassed View that pops up the keyboard when it receives a &#39;touch up&#39; in onTouchEvent.  It shows this by requesting focus, retrieving the InputMethodManager, and then calling showSoftInput.

Now I need to figure out how to capture the tapped letters of the soft keyboard, _as they are pressed_.  I am currently only getting a response when the Next/Done button is pressed on the soft keyboard. 

Here is my class:

    public class BigGrid extends View {
    
    	private static final String TAG = &quot;BigGrid&quot;;
    
    	public BigGrid(Context context) {
    		super(context);
    		setFocusableInTouchMode(true); // allows the keyboard to pop up on
    		                               // touch down
    
    		setOnKeyListener(new OnKeyListener() {
    			public boolean onKey(View v, int keyCode, KeyEvent event) {
    				Log.d(TAG, &quot;onKeyListener&quot;);
    				if (event.getAction() == KeyEvent.ACTION_DOWN) {
    					// Perform action on key press
    					Log.d(TAG, &quot;ACTION_DOWN&quot;);
    					return true;
    				}
    				return false;
    			}
    		});
    	}
    
    	@Override
    	public boolean onTouchEvent(MotionEvent event) {
    		super.onTouchEvent(event);
    		Log.d(TAG, &quot;onTOUCH&quot;);
    		if (event.getAction() == MotionEvent.ACTION_UP) {
    
    			// show the keyboard so we can enter text
    			InputMethodManager imm = (InputMethodManager) getContext()
    					.getSystemService(Context.INPUT_METHOD_SERVICE);
    			imm.showSoftInput(this, InputMethodManager.SHOW_FORCED);
    		}
    		return true;
    	}
    
    	@Override
    	public InputConnection onCreateInputConnection(EditorInfo outAttrs) {
    		Log.d(TAG, &quot;onCreateInputConnection&quot;);
    
    		BaseInputConnection fic = new BaseInputConnection(this, true);
    		outAttrs.actionLabel = null;
    		outAttrs.inputType = InputType.TYPE_CLASS_TEXT;
    		outAttrs.imeOptions = EditorInfo.IME_ACTION_NEXT;
    		return fic;
    	}
    
    	@Override
    	public boolean onCheckIsTextEditor() {
    		Log.d(TAG, &quot;onCheckIsTextEditor&quot;);
    		return true;
    	}
    
    	@Override
    	public void onDraw(Canvas canvas) {
    		super.onDraw(canvas);
    
    		canvas.drawColor(R.color.grid_bg);
    		// .
    		// .
    		// alot more drawing code...
    		// .
    	}
    }

The keyboard shows, but my onKeyListener only fires when I press the &#39;Next&#39; button on the keyboard.  I need which character is tapped, so that I can display it in my onDraw() method.



How to capture soft keyboard input in a View?

I am trying to implement a single-line text view that will scroll automatically. But I unfortunatly cannot get it to work. The AutoScrollTextView is declared inside a LinearLayout (width and height = fill_parent). The class basically uses a Handler that calls itself to scroll by a given amount. I have simplified the code to only show a text view that should be scrolling by 5 pixels every second.

The log output is correct, the getScrollX() method returns the appropriate scrollX position. 

If I don&#39;t call `requestLayout()`, nothing gets drawn. `invalidate()` has no effect.

Would anybody have a clue?


    public class AutoScrollTextView extends TextView {
    
    	public AutoScrollTextView(Context context, AttributeSet attrs, int defStyle) {
    		super(context, attrs, defStyle);
    		setSingleLine();
    		setEllipsize(null);
    		setText(&quot;Single-line text view that scrolls automatically if the text is too long to fit in the widget&quot;);
    	}
    
    	// begin to scroll the text from the original position
    	public void startScrolling() {
    		scrollHandler.sendEmptyMessage(0);
    	}
    
    	private Handler scrollHandler = new Handler() {
    		private static final int REFRESH_INTERVAL = 1000;
    
    		public void handleMessage(Message msg) {
    			scrollBy(5, 0);
    			requestLayout();
    			Log.debug(&quot;Scrolled to &quot; + getScrollX() + &quot; px&quot;);
    			sendEmptyMessageDelayed(0, REFRESH_INTERVAL);
    		}
    	};
    }



Android automatic horizontally scrolling TextView

I have `TextView` with `drawableLeft` &amp; `drawableRight` in List item. 
The problem is, whenever the height of `TextView` is larger, `drawableLeft` &amp; `drawableLeft` didn&#39;t automatically scale based on the height of the `TextView`.

Is it possible to scale the height of `drawableLeft` &amp; `drawableRight` in `TextView` ?
