在我的自定义键盘应用程序中实现了onDraw方法后，我的应用程序似乎占用了大量电池和内存。我刚刚找到了一种通过onDraw方法在键盘上绘制圆圈的方法，该方法扩展了keyboardView。 我的onDraw课程如下，有人可以看看这个。
@Override
public void onDraw(Canvas canvas) {
super.onDraw(canvas);
healA = ddKeys_Master.autohealing;
phealA = ddKeys_Master.autophealing;
Paint paint = new Paint();
paint.setTextAlign(Paint.Align.CENTER);
//get all your keys and draw whatever you want
List<Keyboard.Key> keys = getKeyboard().getKeys();
for (Keyboard.Key key : keys) {
if (key.label != null) {
paint.setColor(Color.parseColor("#66cccc"));
switch (key.codes[0]) {
case 888:
if (healA && phealA) {
if (ddKeys_Master.healcount >= ddKeys_Master.autoHealCount) {
paint.setColor(Color.parseColor("#ef0404")); //red

canvas.drawCircle(17 * scale, 17 * scale, 7 * scale, paint);

如何让代码更顺畅以节省电池？
