Can anybody please guide me how to write the code for opening the new image after clicking the imagebutton in android. I have tried something like this:
package com.example.imageButton;
import android.app.Activity; import android.os.Bundle;
import android.view.View; import android.widget.ImageButton;
public class imageButton extends Activity {
private static ImageButton seqIBtn;//these are the three imageButton private static ImageButton vidIBtn;private static ImageButton infoIBtn; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); seqIBtn = (ImageButton) findViewById(R.id.btnSequence); vidIBtn = (ImageButton) findViewById(R.id.btnVideo); infoIBtn = (ImageButton) findViewById(R.id.btnInfo);}
in my android application there are number of images in drawable folder. in my layout two buttons: back and forward button.on clicking next and back buttons different-2 image get loaded on the same layout(common for all images). Problem:i am able to load images in next button click but as i click on back button no image got loaded.

View 2 Replies View RelatedI'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 2 Replies View RelatedI started a small android application to learn. I placed an input text and button on the screen. That shows on the emulator. After i press the button(which has an onClickListener) the application cracks and tells me on the screen of the emulator : "The application... has stopped unexpectably.Try again" and i have a "Force close", which of course closes the application.
I cleaned and rebuild the project a lot of times. i have no errors shown.(using eclipse)

View 6 Replies View RelatedI 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...
