I'm developing an app of wallpapers. In it I have more than 100 images. I'm using 2 buttons to change an image to the next one and backward. Now I want to use a third button which will open the complete list of the names of drawable images and this list should move up and down. If I select the desired image name then it should open that image.
This list also has 2 buttons on top of it, one to go to the image and one to cancel. Here is what it would look like:
Here is my XML layout.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:gravity="fill"
android:orientation="vertical"
android:weightSum="100" >
<ImageView
android:id="#+id/idImageViewPic"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="100"
android:adjustViewBounds="true"
android:background="#66FFFFFF"
android:maxHeight="91dip"
android:maxWidth="47dip"
android:padding="10dip"
android:src="#drawable/r0" />
<LinearLayout android:id="#+id/linearLayout1"
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
<Button
android:id="#+id/bprev"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="Back" >
</Button>
<Button
android:id="#+id/bnext"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="Next" >
</Button>
</LinearLayout>
</LinearLayout>
My Main Activity:
public class Main extends Activity {
private ImageView hImageViewPic;
private Button iButton, gButton;
private int currentImage = 0;
int[] images = { R.drawable.r1, R.drawable.r2, R.drawable.r3, R.drawable.r4, R.drawable.r5, R.drawable.r6, R.drawable.r7, R.drawable.r8, R.drawable.r9, R.drawable.r10 };
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
hImageViewPic = (ImageView)findViewById(R.id.idImageViewPic);
iButton = (Button) findViewById(R.id.bnext);
gButton = (Button) findViewById(R.id.bprev);
//Just set one Click listener for the image
iButton.setOnClickListener(iButtonChangeImageListener);
gButton.setOnClickListener(gButtonChangeImageListener);
}
View.OnClickListener iButtonChangeImageListener = new OnClickListener() {
public void onClick(View v) {
//Increase Counter to move to next Image
currentImage++;
currentImage = currentImage % images.length;
hImageViewPic.setImageResource(images[currentImage]);
}
};
View.OnClickListener gButtonChangeImageListener = new OnClickListener() {
public void onClick(View v) {
//Increase Counter to move to next Image
currentImage--;
currentImage = currentImage % images.length;
hImageViewPic.setImageResource(images[currentImage]);
}
};}
If I use another button in XML then what should I write in the Main Activity? Is there a better way to do this?
i think , what you can do is :
you have list of drawables/bitmaps device .
Drawable myDrawable = getResources().getDrawable(R.drawable.yourImage); // Drawables
Bitmap myLogo = ((BitmapDrawable) myDrawable).getBitmap();
imageView.setImageBitmap(myLogo);
if images is selected from device , or you have paths :
Uri selectedImage = convert your image path into URI ;
Bitmap bitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(), selectedImage);
userImg.setImageBitmap(bitmap);
Edited :
At last , but before this line ,
ImageViewPic.setImageResource(images[currentImage]) ;
Add this line :
Drawable myDrawable = getResources().getDrawable(R.drawable.yourImage); // Drawables
Bitmap currentImage= ((BitmapDrawable) myDrawable).getBitmap();
then add
ImageViewPic.setImageResource(images[currentImage]) ;

well i'm looking for a way to flip the button on a linear layout vertical here is a screen shot of the buttons
the xml code is
<LinearLayout
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="bottom"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true"
android:id="#+id/buttons_layout">
<ImageButton
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/iv_green"
android:layout_weight="1.0"
android:src="#drawable/leaf_green"
android:layout_gravity="fill_vertical"
android:scaleType="fitXY"
android:onClick="HandleClick" />
<ImageButton
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/iv_other"
android:layout_weight="1.0"
android:src="#drawable/leaf_other"
android:layout_gravity="fill_vertical"
android:scaleType="fitXY"
android:onClick="HandleClick" />
<ImageButton
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/iv_red"
android:layout_weight="1.0"
android:src="#drawable/leaf_red"
android:layout_gravity="fill_vertical"
android:scaleType="fitXY"
android:onClick="HandleClick" />
<ImageButton
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/iv_yellow"
android:layout_weight="1.0"
android:src="#drawable/leaf_yellow"
android:layout_gravity="fill_vertical"
android:scaleType="fitXY"
android:onClick="HandleClick" />
</LinearLayout>
what i want to do is that when i push flip button on (which is another button) i want to change the position of the current button i will explain in pics:
okay guys i used the idea that Arnab Told me about in the post below, well i want to randomly flip the image buttons so i did the following script:
public void onClick(View v) {
btnsLayout.removeAllViews();
ArrayList<Integer> a = new ArrayList<Integer>();
for(int i = 0; i < 4; i++)
{
a.add(i);
}
Collections.shuffle(a);
btnsLayout.addView(Other, a.get(0).intValue());
btnsLayout.addView(Green, a.get(1).intValue());
btnsLayout.addView(Red,a.get(2).intValue());
btnsLayout.addView(Yellow,a.get(3).intValue());
}
the application is crashing the crash reason is:
java.lang.IndexOutOfBoundsException: index=2 count=1
what does it means ?
Thank you !
You can do this inside onCLick(View view) of Flip Button:
// Get all the views
LinearLayout btnsLayout = (LinearLayout) findViewById(R.id.buttons_layout);
ImageButton ivGreen = (ImageButton) findViewById(R.id.iv_green);
ImageButton ivOther = (ImageButton) findViewById(R.id.iv_other);
ImageButton ivRed = (ImageButton) findViewById(R.id.iv_red);
ImageButton ivYellow = (ImageButton) findViewById(R.id.iv_yellow);
// Remove views
btnLayout.removeView(ivGreen);
btnLayout.removeView(ivRed);
// ReAdd views in new index[Index 0 = position 1, Index 2 = position 3]
btnLayout.addView(ivRed, 0);
btnLayout.addView(ivGreen, 2);
Similarly :
// Remove views
btnLayout.removeView(ivOther);
btnLayout.removeView(ivYellow);
// ReAdd views in new index[Index 1 = position 2, Index 3 = position 4]
btnLayout.addView(ivYellow, 1);
btnLayout.addView(ivOther, 3);
First, you should rename the ids of the ImageButtons like :
<ImageButton
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/first_leaf"
android:layout_weight="1.0"
android:src="#drawable/leaf_green"
android:layout_gravity="fill_vertical"
android:scaleType="fitXY"
android:onClick="HandleClick" />
<ImageButton
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/second_leaf"
android:layout_weight="1.0"
android:src="#drawable/leaf_other"
android:layout_gravity="fill_vertical"
android:scaleType="fitXY"
android:onClick="HandleClick" />
<ImageButton
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/third_leaf"
android:layout_weight="1.0"
.../>
Then find your flip button in your java class and set an OnClickListener
like this:
myFlipButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
}
}):
Then, in the onClick function, perform the changes:
myFlipButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
myFirstLeaf.setImageDrawable(getResources().getDrawable(R.drawable.leaf_red));
mySecondLeaf.setImageDrawable(getResources().getDrawable(R.drawable.leaf_yellow));
...
}
});
Hope it helps.
You can use the imgButton.setBackgroundResource(); method.
button.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View view) {
imgButton1.setBackgroundResource(R.drawable.image3);
imgButton3.setBackgroundResource(R.drawable.image1);
}
});
If you want to swap the views you need to use a ViewGroup and you can set the index accordingly.
How do I change the position of a view in a Linear Layout.?
Hello Using Arnab Suggestion and some tuning i found a solution: the problem was that you need to insert the index 1 2 3 4 you can't randomly add the views to the linear layout.
public void addListenerOnButton() {
Button flip = (Button) findViewById(R.id.btn_flip);
final LinearLayout btnsLayout = (LinearLayout) findViewById(R.id.buttons_layout);
final ImageView Other = (ImageView) findViewById(R.id.iv_other);
final ImageView Green = (ImageView) findViewById(R.id.iv_green);
final ImageView Red = (ImageView) findViewById(R.id.iv_red);
final ImageView Yellow = (ImageView) findViewById(R.id.iv_yellow);
flip.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
btnsLayout.removeAllViews();
ArrayList<Integer> a = new ArrayList<Integer>();
for (int i = 0; i < 4; i++) {
a.add(i);
}
Collections.shuffle(a);
for (int k = 0; k<=3 ; k++){
if (a.get(0).intValue() == k) {
btnsLayout.addView(Other, a.get(0).intValue());
}
if (a.get(1).intValue() == k) {
btnsLayout.addView(Green, a.get(1).intValue());
}
if (a.get(2).intValue() == k) {
btnsLayout.addView(Red, a.get(2).intValue());
}
if (a.get(3).intValue() == k) {
btnsLayout.addView(Yellow, a.get(3).intValue());
}
}
}
I have a test code using the View Property Animation to switch locations of two buttons. The code is as below:
public class TestAnimationActivity extends Activity {
private View mainView;
private View TempView;
private Button B1, B2, B3;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Inflate your view
setContentView(R.layout.main_test);
mainView = findViewById(R.id.mainTest);
B1 = (Button) mainView.findViewById(R.id.B1);
B2 = (Button) mainView.findViewById(R.id.B2);
B3 = (Button) mainView.findViewById(R.id.B3);
OnClickListener OCL = new OnClickListener(){
#Override
public void onClick(View v) {
if(TempView == null){
TempView = v;
}else{
int originalPos1[] = new int[2];
TempView.getLocationOnScreen( originalPos1 );
int originalPos2[] = new int[2];
v.getLocationOnScreen( originalPos2 );
v.animate().translationX((float)originalPos1[0] - (float)originalPos2[0]);
v.animate().translationY((float)originalPos1[1] - (float)originalPos2[1]);
TempView.animate().translationX((float)originalPos2[0] - (float)originalPos1[0]);
TempView.animate().translationY((float)originalPos2[1] - (float)originalPos1[1]);
TempView = null;
}
}};
B1.setOnClickListener(OCL);
B2.setOnClickListener(OCL);
B3.setOnClickListener(OCL);
}
}
The XML file is as below
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/mainTest"
android:layout_width="match_parent"
android:layout_height="match_parent"

<Button
android:id="#+id/B1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#B4B4B4"
android:gravity="center" />
<Button
android:id="#+id/B2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#470047"
android:gravity="center" />
<Button
android:id="#+id/B3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#000000"
android:gravity="center" />
</LinearLayout>
When I was testing this code on my phone. The animation did not work properly.
Two buttons will switch position the first time, but the button will go to wrong position if I continue clicking them. It seems that the button still calculate the position it should move to based on its original location when the app launched.
Anyone knows what is going wrong?
I have searched a lot but I got samples to fetch thumbnail from an Url or from Http,
but I actually need to get thumbnail of an image from my own directory on sdcard withot accesing the Android default thumbnail directory, thats is I need to fetch a thumbnail of an image from
mnt/sdcard/myown/1.png
Can anybody help for this please?
Thanks in advance.
Environment.getExternalStorageDirectory() returns "/mnt/sdcard"
String imagePath = Environment.getExternalStorageDirectory().toString() + PATH_TO_IMAGE;
Bitmap bitmap = BitmapFactory.decodeFile(imagePath);
#Override
public void onCreate(Bundle savedInstanceState) {
button1 = (Button) findViewById(R.id.button1);
button1.setOnClickListener(onClickListener);
image = (ImageView) findViewById(R.id.imageView1);
}
private OnClickListener onClickListener = new OnClickListener() {
#Override
public void onClick(final View v) {
switch(v.getId()){
case R.id.button1:
String imagePath = Environment.getExternalStorageDirectory().toString() +"/myown/1.png";
Bitmap bitmap = BitmapFactory.decodeFile(imagePath);
image.setImageBitmap(bitmap);
break;
}
}
};

I'm using ViewFLipper with Random.nextInt(). to change layouts onClick (Button). Now I have 3 xml layouts. 1_view.xml 2_view.xml 3_view.xml. Starting from 1_view.xml I have a button there. When button clicked I should get a random layout. it works. But the problem is now, sometimes I get the same layout (1_view.xml). When a user clicks a button on (1_view.xml), I want them to go to the layouts I have left (2_view.xml and 3_view.xml).
Codes

</ViewFlipper>
</LinearLayout>
Main.java
// FlipperView
MyViewFlipper = (ViewFlipper) findViewById(R.id.viewFlipper1);
TVRight = (TextView) findViewById(R.id.TVRight);
TVLeft = (TextView) findViewById(R.id.TVLeft);
// 1_view.xml
Q1_btn1 = (Button) findViewById(R.id.btn_1);
Q1_btn2 = (Button) findViewById(R.id.btn_2);
Q1_btn3 = (Button) findViewById(R.id.btn_3);
Q1_btn4 = (Button) findViewById(R.id.btn_4);
Q1_btn1.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
Wrongnum++;
WrongResult.setText(Integer.toString(Wrongnum));
}
});
Q1_btn2.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
Rightnum++;
RightResult.setText(Integer.toString(Rightnum));
Random RandomView = new Random();
MyViewFlipper.setDisplayedChild(RandomView.nextInt(3));
}
});
Q1_btn3.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
Wrongnum++;
WrongResult.setText(Integer.toString(Wrongnum));
}
});
Q1_btn4.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
Wrongnum++;
WrongResult.setText(Integer.toString(Wrongnum));
}
});
You can do this in your code:
Random RandomView = new Random();
int nextViewIndex = RandomView.nextInt(3);
while (nextViewIndex == MyViewFlipper.getDisplayedChild()) {
nextViewIndex = RandomView.nextInt(3);
}
MyViewFlipper.setDisplayedChild(nextViewIndex);
Basically just call Random.nextInt() until it doesn't match current viewFlipper's index.
To only show a viewFlipper once randomly:
// Intialize this once
List<Integer> vfIndices = new ArrayList<Integer>();
for (int i = 0; i < MyViewFlipper.getChildCount(); i++) {
vfIndices.add(i);
}
// when button is clicked
if (vfIndices.size() == 0) {
return; // no more view flipper to show!
}
int viewIndex = RandomView.nextInt(vfIndices.size());
MyViewFlipper.setDisplayedChild(vfIndices.get(viewIndex));
vfIndicies.remove(viewIndex);
The idea is use an ArrayList to keep track of the viewFlipper index that has not been shown. When button is clicked, pick an index randomly from this array and set the viewFlipper to. Then remove that index from the ArrayList. Next time the button is clicked, it will show one of the remaining flippers.
I've a series of still images and total of more than 500 images presented in drawable directory. I need to make an animation (load about 20 images per second). I want it to run smoothly and with no Out Of Memory Exception.
I've idea to do this that images for 2 to 3 seconds (40 to 60 images) should load in memory and displayed and then they should disposed off (release the memory) and then images for next 2 to 3 seconds should load. This technique can prevent Out Of Memory Exception. Its just an idea, I dont know whether its a good idea or not. Please guide me some better idea with some code to go with... If my idea is much better and can work then please tell me some helping code to do that.
After reading replies and doing as you suggest, I've written some code like this:
<?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"
android:id="#+id/llMain">
<ViewFlipper android:id="#+id/imageflipper"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<ImageView android:id="#+id/ImageView01"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:scaleType="centerInside"
android:layout_gravity="center" />
</ViewFlipper>
</LinearLayout>
and here is my code for doing animation:
public class Animation extends Activity {
ViewFlipper flipper;
int myIndex = 216;
private final Handler handler = new Handler();
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
flipper=(ViewFlipper)findViewById(R.id.imageflipper);
doTheAutoRefresh();
//displayData();
}
private void doTheAutoRefresh() {
handler.postDelayed(new Runnable() {
public void run(){
displayData(); // this is where you put your refresh code
doTheAutoRefresh();
}
}, 30);
}
private void displayData()
{
Resources r = getResources();
if(myIndex > 230){
myIndex = 216;
ImageView myImg = (ImageView)findViewById(R.id.ImageView01);
myImg.setImageResource(r.getIdentifier("drum0" + myIndex, "drawable", "com.vt.animation"));
myIndex += 1;
flipper.showNext();
}
else{
ImageView myImg = (ImageView)findViewById(R.id.ImageView01);
myImg.setImageResource(r.getIdentifier("drum0" + myIndex, "drawable", "com.vt.animation"));
myIndex += 1;
flipper.showNext();
}
}
}
but its very slow. I've set up the refresh time to 30 milliseconds but actually its not refreshing too fast rather its refresh time is about 1 second. Any suggestion to make it fast to feel like real animation?
Thanks,
Use a FrameAnimation, eg in res/drawable/movie.xml:
<?xml version="1.0" encoding="utf-8"?>
<animation-list xmlns:android="http://schemas.android.com/apk/res/android"
android:oneshot="true">
<item android:drawable="#drawable/frame1" android:duration="50" />
<item android:drawable="#drawable/frame2" android:duration="50" />
<item android:drawable="#drawable/frame3" android:duration="50" />
etc...
</animation-list>
And then in Java:
imageView.setBackgroundResource(R.drawable.movie);
AnimationDrawable anim = (AnimationDrawable) imageView.getBackground();
anim.start();
OK. The biggest problem and the easiest solution I got to go with after so many days. I would never expect that it would be so easy to do... :D
I've used both handler and timer to achieve with just an image view, no flipper, no animator nothing else at all... Here is my solution:
----- main.xml file -----
<?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"
android:background="#drawable/background">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/imageView1">
</ImageView>
And here is the way I have done it:
public class MainActivity extends Activity {
private ImageView _imagView;
private Timer _timer;
private int _index;
private MyHandler handler;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
handler= new MyHandler();
_imagView=(ImageView) findViewById(R.id.imageView1);
_index=0;
_timer= new Timer();
_timer.schedule(new TickClass(), 500, 200);
}
private class TickClass extends TimerTask
{
#Override
public void run() {
// TODO Auto-generated method stub
handler.sendEmptyMessage(_index);
_index++;
}
}
private class MyHandler extends Handler
{
#Override
public void handleMessage(Message msg) {
// TODO Auto-generated method stub
super.handleMessage(msg);
try {
Bitmap bmp= BitmapFactory.decodeStream(MainActivity.this.getAssets().open("drum_"+_index+".png"));
_imagView.setImageBitmap(bmp);
Log.v("Loaing Image: ",_index+"");
} catch (IOException e) {
// TODO Auto-generated catch block
Log.v("Exception in Handler ",e.getMessage());
}
}
}
}
Note: I've placed all my images to asset directory.
Its so simple as it can, nothing big to do...
I hope it'll be helpful for someone looking to go like this :)
Loading several images is very expensive.
I think it's better to load a single image containing all the movements of that certain animation. An animation strip.
private Bitmap animation = BitmapFactory.decodeResource(getResources(), R.drawable.myPng);
The idea is to traverse the bitmap.
Well, I'm using viewFlipper, switching between views. Good thing about this one is that u can see previous picture sliding out while the new one slides in.
Inside image displaying method:
if (direction == NEXT) {
viewFlipper.setInAnimation(slideLeftIn);
viewFlipper.setOutAnimation(slideLeftOut);
if (currImg < max)
currImg++;
if (currImg == max)
currImg = 0;
if (currentView == 0) {
currentView = 1;
ImageView iv = (ImageView) findViewById(R.id.ImageView02);
iv.setImageResource(images[currImg]);
} else if (currentView == 1) {
currentView = 2;
ImageView iv = (ImageView) findViewById(R.id.ImageView03);
iv.setImageResource(images[currImg]);
} else {
currentView = 0;
ImageView iv = (ImageView) findViewById(R.id.ImageView01);
iv.setImageResource(images[currImg]);
}
viewFlipper.showNext();
}
else if (direction == PREV) {
viewFlipper.setInAnimation(slideRightIn);
viewFlipper.setOutAnimation(slideRightOut);
if (currImg > 0)
currImg--;
else if (currImg <= 0)
currImg = (max-1);
if (currentView == 0) {
currentView = 2;
ImageView iv = (ImageView) findViewById(R.id.ImageView03);
iv.setImageResource(images[currImg]);
} else if (currentView == 2) {
currentView = 1;
ImageView iv = (ImageView) findViewById(R.id.ImageView02);
iv.setImageResource(images[currImg]);
} else {
currentView = 0;
ImageView iv = (ImageView) findViewById(R.id.ImageView01);
iv.setImageResource(images[currImg]);
}
viewFlipper.showPrevious();
And inside XML file:
<ViewFlipper android:id="#+id/imageflipper"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<ImageView android:id="#+id/ImageView01"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:scaleType="centerInside"
android:layout_gravity="center" />
<ImageView android:id="#+id/ImageView02"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:scaleType="centerInside"
android:layout_gravity="center" />
<ImageView android:id="#+id/ImageView03"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:scaleType="centerInside"
android:layout_gravity="center" />
</ViewFlipper>
