Example 76 with DisplayMetrics

use of android.util.DisplayMetrics in project Genius-Android by qiujuer.

the class BalloonMarker method resetSizes.

public void resetSizes(String maxValue) {
    DisplayMetrics displayMetrics = getResources().getDisplayMetrics();
    //Account for negative numbers... is there any proper way of getting the biggest string between our range????
    mNumber.setText(String.format("-%s", maxValue));
    //Do a first forced measure call for the TextView (with the biggest text content),
    //to calculate the max width and use always the same.
    //this avoids the TextView from shrinking and growing when the text content changes
    int wSpec = MeasureSpec.makeMeasureSpec(displayMetrics.widthPixels, MeasureSpec.AT_MOST);
    int hSpec = MeasureSpec.makeMeasureSpec(displayMetrics.heightPixels, MeasureSpec.AT_MOST);
    mNumber.measure(wSpec, hSpec);
    mWidth = Math.max(mNumber.getMeasuredWidth(), mNumber.getMeasuredHeight());
    removeView(mNumber);
    addView(mNumber, new FrameLayout.LayoutParams(mWidth, mWidth, Gravity.LEFT | Gravity.TOP));
