android 第三个开机动画的修改

在工作的过程中，有客户要求修改动画，顺便看了一下，仅供参考。

首先在frameworks\base\cmds\bootanimation\BootAnimation.cpp目录下

在bool BootAnimation::android()中修改一下代码
{
    int i = 0;
    initTexture(&mAndroid[0], mAssets, "images/android-logo-mask-1.png");
 initTexture(&mAndroid[1], mAssets, "images/android-logo-mask-2.png");
  initTexture(&mAndroid[2], mAssets, "images/android-logo-mask-3.png");
   initTexture(&mAndroid[3], mAssets, "images/android-logo-mask-4.png");
    initTexture(&mAndroid[4], mAssets, "images/android-logo-mask-5.png");
   initTexture(&mAndroid[5], mAssets, "images/android-logo-mask-6.png");
    initTexture(&mAndroid[6], mAssets, "images/android-logo-shine.png")

然后在做以下红色部分修改.

do {
        nsecs_t now = systemTime();
        double time = now - startTime;
        float t = 4.0f * float(time / us2ns(16667)) / mAndroid[6].w;
        GLint offset = (1 - (t - floorf(t))) * mAndroid[6].w;
        GLint x = xc - offset;

        glDisable(GL_SCISSOR_TEST);
        glClear(GL_COLOR_BUFFER_BIT);

        glEnable(GL_SCISSOR_TEST);
        glDisable(GL_BLEND);
        glBindTexture(GL_TEXTURE_2D, mAndroid[6].name);
        glDrawTexiOES(x,                 yc, 0, mAndroid[6].w, mAndroid[6].h);
        glDrawTexiOES(x + mAndroid[6].w, yc, 0, mAndroid[6].w, mAndroid[6].h);

        glEnable(GL_BLEND);
        glBindTexture(GL_TEXTURE_2D, mAndroid[i].name);
        glDrawTexiOES(xc, yc, 0, mAndroid[i].w, mAndroid[i].h);

        EGLBoolean res = eglSwapBuffers(mDisplay, mSurface);
       if(i<5)
       i++;
      else
        i = 0;

        if (res == EGL_FALSE)
            break;

        // 12fps: don't animate too fast to preserve CPU
        const nsecs_t sleepTime = 183333 - ns2us(systemTime() - now);
        if (sleepTime > 0)
            usleep(sleepTime);
    } while (!exitPending());

    glDeleteTextures(1, &mAndroid[0].name);
    glDeleteTextures(1, &mAndroid[1].name);
 glDeleteTextures(1, &mAndroid[2].name);
 glDeleteTextures(1, &mAndroid[3].name);
 glDeleteTextures(1, &mAndroid[4].name);
 glDeleteTextures(1, &mAndroid[5].name);
 glDeleteTextures(1, &mAndroid[6].name);
    return false;
}

最后还有根据你所加动画的图片数量去修改BootAnimation.h下的值

  Texture     mAndroid[7];
