    <p>I am trying to implement a segmentated radio button from here: <a href="https://github.com/makeramen/android-segmentedradiobutton" rel="nofollow">https://github.com/makeramen/android-segmentedradiobutton</a> but I need to set the image programmatically and not in XML.</p> <p>This is the source of the custom RadioButton:</p> <pre><code>public class CenteredImageButton extends RadioButton { Drawable image; public CenteredImageButton(Context context, AttributeSet attrs) { super(context, attrs); TypedArray a = context.obtainStyledAttributes(attrs, R.styleable.CompoundButton, 0, 0); image = a.getDrawable(1); setButtonDrawable(android.R.id.empty); } @Override protected void onDraw(Canvas canvas) { super.onDraw(canvas); if (image != null) { image.setState(getDrawableState()); // scale image to fit inside button int imgHeight = image.getIntrinsicHeight(); Log.d("IMAGEHEIGHT", "imageWidth is " + imgHeight); int imgWidth = image.getIntrinsicWidth(); Log.d("IMAGEWIDTH", "imageWidth is " + imgWidth); int btnWidth = getWidth(); Log.d("BUTTONWIDTH", "buttonWidth is " + btnWidth); int btnHeight = getHeight(); Log.d("BUTTONHEIGHT", "buttonHeight is " + btnHeight); float scale; if (imgWidth &lt;= btnWidth &amp;&amp; imgHeight &lt;= btnHeight) { scale = 1.0f; } else { scale = Math.min((float) btnWidth / (float) imgWidth, (float) btnHeight / (float) imgHeight); } Log.d("SCALE", "scale is " + scale); int dx = (int) ((btnWidth - imgWidth * scale) * 0.5f + 0.5f); Log.d("DX", "dx is " + dx); int dy = (int) ((btnHeight - imgHeight * scale) * 0.5f + 0.5f); Log.d("DY", "dy is " + dy); image.setBounds(dx, dy, (int) (dx + imgWidth * scale), (int) (dy + imgHeight * scale)); image.draw(canvas); } } </code></pre> <p>I am setting the drawable in another file like this:</p> <pre><code>private void setButtonImageProperties(RadioButton button,Drawable drawable){ button.setGravity(Gravity.CENTER); Resources resources = this.context.getResources(); float dipValue = TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 60, resources.getDisplayMetrics()); float dipValue1 = TypedValue.applyDimension( TypedValue.COMPLEX_UNIT_DIP, 80, resources.getDisplayMetrics()); button.setMinHeight((int) dipValue); button.setMinWidth((int) dipValue1); button.setButtonDrawable(drawable); } </code></pre> <p>Please anyone, advise. I really need helping hand. Thanks.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
