Example 51 with TextPaint

use of android.text.TextPaint in project Resurrection_packages_apps_Settings by ResurrectionRemix.

the class ChartGridView method makeLabel.

private Layout makeLabel(CharSequence text) {
    final Resources res = getResources();
    final TextPaint paint = new TextPaint(Paint.ANTI_ALIAS_FLAG);

    paint.setTextSize(mLabelSize);
    return new StaticLayout(text, paint, (int) Math.ceil(Layout.getDesiredWidth(text, paint)), Layout.Alignment.ALIGN_NORMAL, 1.f, 0, true);
}

Example 52 with TextPaint

use of android.text.TextPaint in project android_frameworks_base by ResurrectionRemix.

the class PackageItemInfo method loadSafeLabel.

/**
     * Same as {@link #loadLabel(PackageManager)} with the addition that
     * the returned label is safe for being presented in the UI since it
     * will not contain new lines and the length will be limited to a
     * reasonable amount. This prevents a malicious party to influence UI
     * layout via the app label misleading the user into performing a
     * detrimental for them action. If the label is too long it will be
     * truncated and ellipsized at the end.
     *
     * @param pm A PackageManager from which the label can be loaded; usually
     * the PackageManager from which you originally retrieved this item
     * @return Returns a CharSequence containing the item's label. If the
     * item does not have a label, its name is returned.
     *
     * @hide
