How to re-scale Bitmap image size?

How to re-scale Bitmap image size? - android

Hi guys I am trying to load a image from a url and after loading that i am trying to re scale it such that it fits the whole screen after that the text and the buttons present are available below the image which are wrapped around using scroll view
this is my fragment
public class FirstFragment extends Fragment {
ImageView im;
Bitmap bitmap;
Drawable dr;
Bitmap bitap;
Bitmap newBitmap;
RelativeLayout rel;
View v;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
v = inflater.inflate(R.layout.first_frag, container, false);
rel = (RelativeLayout) v.findViewById(R.id.relativla);
rel.setVisibility(View.INVISIBLE);
new LoadImage().execute("http://opinions.esy.es/bg.jpg");
Button b = (Button) v.findViewById(R.id.navi);
im = (ImageView) v.findViewById(R.id.imageView);
b.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent i = new Intent(getContext(), Navi.class);
startActivity(i);
}
});
return v;
}
public static FirstFragment newInstance(String text) {
FirstFragment f = new FirstFragment();
Bundle b = new Bundle();
b.putString("msg", text);
f.setArguments(b);
return f;
}
private class LoadImage extends AsyncTask<String, String, Bitmap> {
#Override
protected void onPreExecute() {
super.onPreExecute();
}
protected Bitmap doInBackground(String... args) {
try {
bitmap = BitmapFactory.decodeStream((InputStream) new URL(args[0]).getContent());
} catch (Exception e) {
e.printStackTrace();
}
return bitmap;
}
protected void onPostExecute(Bitmap image) {
if(image != null){
dr = new BitmapDrawable(getResources(),image);
bitap = ((BitmapDrawable) dr).getBitmap();
float scalingFactor = getBitmapScalingFactor(bitap);
Bitmap newBitmap = Util.ScaleBitmap(bitmap, scalingFactor);
im.setImageBitmap(newBitmap);
}else{
Toast.makeText(getContext(), "Image Does Not exist or Network Error", Toast.LENGTH_SHORT).show();
}
}
}
private float getBitmapScalingFactor(Bitmap bm) {
Toast.makeText(getContext(),"entered here",Toast.LENGTH_LONG).show();
// Get display width from device
int displayWidth = getActivity().getWindowManager().getDefaultDisplay().getWidth();
// Get margin to use it for calculating to max width of the ImageView
RelativeLayout.LayoutParams layoutParams =
(RelativeLayout.LayoutParams)this.im.getLayoutParams();
int leftMargin = layoutParams.leftMargin;
int rightMargin = layoutParams.rightMargin;
// Calculate the max width of the imageView
int imageViewWidth = displayWidth - (leftMargin + rightMargin);
rel.setVisibility(View.VISIBLE);
// Calculate scaling factor and return it
return ( (float) imageViewWidth / (float) bm.getWidth() );
}
}
My Util class
public class Util {
public static Bitmap ScaleBitmap(Bitmap bm, float scalingFactor) {
int scaleHeight = (int) (bm.getHeight() * scalingFactor);
int scaleWidth = (int) (bm.getWidth() * scalingFactor);
return Bitmap.createScaledBitmap(bm, scaleWidth, scaleHeight, true);
}
}

It the toast insider the getBitmapScaling factor is called after the relative layout is viewed
Hope you guys can help me solve my issue

try add these
WindowManager wm = (WindowManager) getSystemService(Context.WINDOW_SERVICE);
DisplayMetrics dm = new DisplayMetrics();
wm.getDefaultDisplay().getMetrics(dm);
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(dm.widthPixels, dm.heightPixels);
im.setLayoutParams(params);
below im.setImageBitmap(newBitmap); onPostExecute

Try this code it take a url converts it into bitmap and then set wallpaper according to screen size :
Declare variables

Initialise your Views

First image appearing small in size and on top left corner in a viewpager when rotate the device

Hi in my application i am using the Viewpager with PagerAdapter. it contains n number of images. but when i rotate the device when viewpager is on first image then the image shift to top left corner and appears very small. please have a look in the attached image.
code which i am using
public class CustomViewPager extends ViewPager {

child.measure(widthMeasureSpec, MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED));
int h = child.getMeasuredHeight();
if (h > height)
height = h;
}
heightMeasureSpec = MeasureSpec.makeMeasureSpec(height, MeasureSpec.EXACTLY);

Android expand and contract animation on Layout

I have a normal Relative Layout with text view and progress bar.
Now, since i have a fixed width and height of the layout the text is properly placed in the center and looks good, onclick of layout we are changing the visibility of progress bar to "Visible", but since i have a fixed width the progress bar is on top of the text.
What i am trying to achieve is , onclick increase the right end width of the layout along with animation.
Here is my code :
<RelativeLayout
android:id="#+id/rellyt"
android:layout_width="150dp"
android:layout_height="35dp"
android:layout_margin="5dp"
android:background="#B7E4FF"
android:clickable="true" >
<TextView
android:id="#+id/txt"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerInParent="true"
android:text="click on this button"
android:textColor="#000000"
android:textSize="14sp" />
<ProgressBar
android:id="#+id/prgbar"
style="#android:style/Widget.ProgressBar.Small"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:layout_marginRight="8dp"
android:visibility="visible" />
</RelativeLayout>
Screen shot of the layout :

Animation
public class ResizeWidthAnimation extends Animation
{
private int mWidth;
private int mStartWidth;
private View mView;
public ResizeWidthAnimation(View view, int width)
{
mView = view;
mWidth = width;
mStartWidth = view.getWidth();
}
#Override
protected void applyTransformation(float interpolatedTime, Transformation t)
{
int newWidth = mStartWidth + (int) ((mWidth - mStartWidth) * interpolatedTime);
mView.getLayoutParams().width = newWidth;
mView.requestLayout();
}
#Override
public void initialize(int width, int height, int parentWidth, int parentHeight)
{
super.initialize(width, height, parentWidth, parentHeight);
}
#Override
public boolean willChangeBounds()
{
return true;
}
}
Usage
if(animate)
{
ResizeWidthAnimation anim = new ResizeWidthAnimation(leftFrame, leftFragmentWidthPx);
anim.setDuration(500);
leftFrame.startAnimation(anim);
}
else
{
this.leftFragmentWidthPx = leftFragmentWidthPx;
LayoutParams lp = (LayoutParams) leftFrame.getLayoutParams();
lp.width = leftFragmentWidthPx;
leftFrame.setLayoutParams(lp);
}

Try this way,hope this will help you to solve your problem.

Android - multiple draw on ImageView

I'm new in Android and I have a problem with my app: I have a layout with an ImageView and more EditTexts and Buttons. I'm trying to draw a circle on the Image View every time I input coordinates in a EditText and push a button.
I found a way to make it work the first time, but if I just copy the same code for the 2nd button it draws the new circle and erases the first one. And I want to have both of them...
Somebody can tell me whet I do wrong? Thanks a lot.
My activity:

Firstly I suppose that "#drawable/est" is the basic image that will be painted. Then Every time that the button is clicked "est" image is reopened so the previous circles aren't saved.
One possible solution is to use a SurfaceView. There are many tutorials on internet about it.
Other solution is not to load "est" image every time, instead of that try saving the canvas and draw the circles one after another.
Hope it helps

The problem is that you only draw 1 circle in your OnClickListener(), and you draw it on a bitmap that you read from a file every time.
Instead you should save the coordinates into a list, and in the click listener draw all the circles from the list.
Like this:
String x11 = P1X.getText().toString();
String z11 = P1Z.getText().toString();
float x1 = Float.valueOf(x11);
float z1 = Float.valueOf(z11);
points.add(new Point(x1, z1));
And then:
for (Point point : points) {
canvas.drawCircle(point.x, point.y, 25, paint1);
}
