Android :: Why Setting TextView.Ellipsize As Marquee Cause Its Sibling View In Linearlayout Redraw
Feb 3, 2010We are using TextView's Ellipsize function to scrolling text in it and there many other controls in our window. We noticed CPU would go up to 50% if text started scrolling. After digging deeper, we found all controls in our layout kept drawing when texts scrolling. We wonder why? And how to avoid all controls redrawing?
View 8 Replies View RelatedAndroid :: Getting A RadioGroup To Redraw With Correct Button Checked
Oct 7, 2010I have a RadioGroup view inside a LinearLayout. The radio buttons are added from dataList. If I call the code below from inside onCreate, the correct button is checked. However the dataList can get updated from time to time and after that happens I call this code again, without destroying the Activity. After that, the view is redrawn but no button is checked. I suspect the RadioGroup checked-button bookkeeping is getting confused by the removeAllViews call. Any ideas what might be going wrong?
View 6 Replies View RelatedAndroid :: LinearLayout Of WebView And Button
Mar 25, 2010I recently struggled with an apparently simple Android layout: I wanted a WebView above a Button. It worked fine with the following parameters:
WebView:
Height: wrap-content
Weight: unset (by the way, what is the default?)
Button:
Height: wrap-content
Weight: unset
However if the web page became too big it spilled out over the button. I tried various combinations of weights and heights, and all except one either completely hide the button, or partially cover it...............

Android :: Button Not Centered Vertically In LinearLayout?
Feb 3, 2010I have a LinearLayout, which only contains one button. I want this button to be centered vertically and aligned to the right. I tried many ways, but I couldn't make this button centered vertically. It is always aligned to the top. I also tried to put a button in RelativeLayout, the button can not be centered vertically either.
The XML is as below. Is there anything wrong with this layout?
<?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="wrap_content" android:background="#E8E3E4">
<Button
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:text="More" android:layout_gravity="right" />
</LinearLayout>

View 3 Replies View RelatedAndroid :: How To Accept An Incoming Call By Clicking A Button
May 6, 2010I'm trying to implement my own phone call handling UI. What I want to do is, if a call comes in, the incoming telephone number and a picture are displayed, and, if I press a button, the incoming call will be accepted/answered.
Sadly, the code does not work. At first, an exception is thrown if I press my answer button:
ActivityNotFoundException: No Activity found to handle Intent {act=android.intent.action.ANSWER
Then I added an entry in the AndroidManifest.xml: I run the app again, there is no exception anymore. However, I doubt the incoming call is not really accepted. Because if the press the Android's screen answer button (green button), the incoming call is accepted and a green in call icon is also displayed on the upper left corner of the emulator screen, while my app doesn't.
I also read the Phone app's source code in android source. There is method such as acceptCall() in the Phone class. But these codes seem difficult for me to use, because there are many imports declaration in the code, such as :
import com.android.internal.telephony.Call;
import com.android.internal.telephony.CallStateException;
import com.android.internal.telephony.CallerInfo;
import com.android.internal.telephony.CallerInfoAsyncQuery;
import com.android.internal.telephony.Connection;
import com.android.internal.telephony.MmiCode;
import com.android.internal.telephony.Phone;
And, if I add these imports in my code, there will be too many errors, such as : "The import com.android.internal.telephony cannot be resolved" What is the right and simple way for my problem?

View 4 Replies View RelatedAndroid :: TextView Inside LinearLayout Stretches The LinearLayout
Aug 21, 2010If I have 2 LinearLayouts split %50/%50 everything is fine. Weights are 1 and 1. As soon as I add a TextView inside the top LinearLayout, it stretches that layout. I use "wrap_content" as the documentation says I should when it comes to weights. As you can see the red and green should be split evenly and text on grey background should be inside red box.
Here is the code:..............
Now if I switch to "fill parent" as follows it actually works but it creates another problem. Here is the code (so far so good):
So looking at above we were forced to use "fill_parent" and we would think like we fixed the problem but here is the problem if we are using "fill_parent" (I took out the textview just to show the problem, textview doesnt make the problem go away anyways):
As you can see I assign the weights 3 (top red) and 2 (bottom green) but what actually happens is they get flipped: The red becomes 2 and bottom becomes 3. Just measure the pixels too see.
Here are the results of the 3 codes: http://imgur.com/iVt8g.jpg

View 6 Replies View RelatedHighlight Selected Item Background After Clicking Back Button
Apr 18, 2013I have to develop one android application.
Here is the scenario:There are many images in a linearlayout. When selected, the layout should be displayed with another(gradient_bg_hover.xml) background. This works well now.
Now, I would like that when I open a new activity and come back to this one, the last selected layout should still be the highlighted one (with the (gradient_bg_hover.xml) background).
Now i have used below code for highlighting the image when pressed:
[HIGH]
LinearLayout ar = new LinearLayout(this);
ar.setOrientation(LinearLayout.VERTICAL);
ar.setPadding(3, 3, 3, 3);
ar.setLayoutParams(artiLayoutParams);
ar.setGravity(Gravity.CENTER);
ar.setBackgroundColor(Color.parseColor("#666666")) ;
[Code]...
In OnClick function i have wrote the below code:
[HIGH]
private OnClickListener mArticleClick = new OnClickListener()
{
@Override
public void onClick ( View v )
{
int object = v.getId();
v.setSelected(true);
[Code]...
Here i have to clicked one item means it is go to next activity.afterthat i have clicked back button means the selected item is stay on highlighted with another background.afterthat i have selected another item means its go to next activity.now i have to click back button means these item only highlight with background....but the pervious item also highlighted....
I wish to need the o/p like :
The last selected item only highlighted after click the back button...
So i have used sharedpreferences :
I have declared int prevPosition = -1; globally...
[HIGH]
ar = new LinearLayout(this);
ar.setOrientation(LinearLayout.VERTICAL);
ar.setPadding(3, 3, 3, 3);
ar.setLayoutParams(artiLayoutParams);
ar.setGravity(Gravity.CENTER);
[Code]...
In Onclick method:
[HIGH]
private OnClickListener mArticleClick = new OnClickListener()
{
@Override
public void onClick ( View v )
{
int object = v.getId();
[Code]...
But my background color is not staying after press the back button...
