How to set image size?

I have splash.png and want this image to occupy all the space on the screen, for example fitXY for ImageView . splash.png has dimensions of 480x767.

What do I need to change in my code?

 public class BitmapConfigView extends LinearLayout { private Bitmap mImage; private Paint mPaint = new Paint(); public BitmapConfigView(Context context) { super(context); BitmapFactory.Options opts = new BitmapFactory.Options(); opts.inPreferredConfig = Bitmap.Config.ARGB_8888; opts.inScaled = false; mImage = BitmapFactory.decodeResource( getResources(), R.drawable.splash, opts); mPaint.setDither(true); setWillNotDraw(false); setOrientation(VERTICAL); setGravity(Gravity.BOTTOM); } @Override protected void onDraw(Canvas canvas) { canvas.drawBitmap(mImage, 0.0f, 0.0f, mPaint); } }

As a result, I used WebView :

 public class TestwebViewimageActivity extends Activity { private WebView wv; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); wv = (WebView) findViewById(R.id.webview); wv.setWebViewClient(new HelloWebViewClient()); wv.setBackgroundColor(0x00000000); wv.getSettings().setBuiltInZoomControls(false); wv.setVerticalScrollBarEnabled(false); wv.setHorizontalScrollBarEnabled(false); wv.loadUrl("file:///android_asset/6.html"); } private class HelloWebViewClient extends WebViewClient { @Override public boolean shouldOverrideUrlLoading(WebView view, String url) { view.loadUrl(url); return true; } } }

main.xml

 <?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:orientation="vertical"> <WebView android:id="@+id/webview" android:layout_width="fill_parent" android:layout_height="fill_parent"/> </LinearLayout>

Scale the bitmap. This is what you are looking for:
android.graphics.Bitmap.createScaledBitmap

This is how I usually use the scaling method.

 public Bitmap getResizedBitmap(Bitmap bm, int newHeight, int newWidth) { int width = bm.getWidth(); int height = bm.getHeight(); float scaleWidth = ((float) newWidth) / width; float scaleHeight = ((float) newHeight) / height; // create a matrix for the manipulation Matrix matrix = new Matrix(); // resize the bit map matrix.postScale(scaleWidth, scaleHeight); // recreate the new Bitmap Bitmap resizedBitmap = Bitmap.createBitmap(bm, 0, 0, width, height, matrix, false); return resizedBitmap; }
