动画在Android中图像的旋转

• 我有，我要不断地围绕一个固定点齿轮的形象。

• I have a gear image which I want to continuously rotate about a fixed point.

此前我被包括在我的Andr​​oid类作为一个ImageView的图像和应用RotateAnimation它实现这一点。

Earlier I was accomplishing this by including the image in my Android class as an ImageView and applying a RotateAnimation to it.

@InjectView(R.id.gear00)              ImageView gear00;
RotateAnimation ra07 = new RotateAnimation(0, 359, 129, 186);
ra07.setDuration(10000);
ra07.setRepeatCount(RotateAnimation.INFINITE);
ra07.setInterpolator(new LinearInterpolator());
gear00.setAnimation(ra07);

基本上，我被注射了ImageView的进级和应用旋转动画。

Basically, I was injecting the ImageView into the class and applying a rotation animation.

不过，我没有使用的ImageView了的奢侈品。我必须使用的位图的并旋转画布上。

However, I dont have the luxury of using an ImageView anymore. I have to use a Bitmap and rotate it on the canvas.

我该如何去完成我在以前是做的的OnDraw（）的方法，用位图在画布上绕一固定点continiously？

How can I go about accomplishing what I was doing earlier in the onDraw() method with a bitmap rotating about a fixed point continiously on the canvas?

EDIT1：

我试过了我下面的code中提到的建议，一个看起来像一个小以下

I tried one of the suggestions mentioned below my code looks a little like the following

在的onCreate（）：

in onCreate():

Matrix matrix = new Matrix();
matrix.setRotate(10, 100, 200);

然后在的OnDraw（）（其中gear00Scaled是位图，在画布上旋转）：

Then in onDraw() (where gear00Scaled is a bitmap to be rotated on the canvas):

canvas.drawBitmap（gear00Scaled，矩阵，新的油漆（））;

canvas.drawBitmap(gear00Scaled, matrix, new Paint());

另一种方法我试过参与节约画布，旋转，然后还原它：

Another method I tried involved saving the canvas, rotating it, then restoring it:

canvas.save（）;
  canvas.rotate（10）;
  canvas.drawBitmap（gear00Scaled，100，200，NULL）;
  canvas.restore（）;

canvas.save();
canvas.rotate(10);
canvas.drawBitmap(gear00Scaled, 100, 200, null);
canvas.restore();

既不似乎工作虽然！
