surfaceflinger测试程序
我想在Android中编写一个本机应用程序进行测试
SurfaceFlinger的。是否有任何简单的程序显示如何创建
Surfaceflinger上的表面，寄存器缓冲区和后缓冲区。

是一个很好的起点。 但我的测试应用程序版本（来自供应商的Eclair）已过时，某些API已移至，您必须：=>=>其次使用将所有事务绑定到SurfaceFlinger表面，例如：和这里有一些示例代码（希望这个编译：P）sp<SurfaceComposerClient> client; sp<SurfaceControl> control; sp<Surface> surface; SurfaceID sid = 0; Surface::SurfaceInfo sinfo; // set up the thread-pool, needed for Binder sp<ProcessState> proc(ProcessState::self()); ProcessState::self()->startThreadPool(); client = new SurfaceComposerClient(); control = client->createSurface(getpid(), sid, 160, 240, PIXEL_FORMAT_RGB_565); surface = control->getSurface(); // global transaction sometimes cannot trigger a redraw //client->openGlobalTransaction(); printf("setLayer...n"); client->openTransaction(); control->setLayer(100000); client->closeTransaction(); printf("setLayer donen"); printf("memset 0xF800...n"); client->openTransaction(); surface->lock(&sinfo); android_memset16((uint16_t*)sinfo.bits, 0xF800, sinfo.s*pfInfo.bytesPerPixel*sinfo.h); surface->unlockAndPost(); client->closeTransaction(); printf("memset 0xF800 donen"); sleep(2); printf("setSize...n"); client->openTransaction(); control->setSize(80, 120); client->closeTransaction(); printf("setSize donen"); sleep(2); printf("memset 0x07E0...n"); client->openTransaction(); surface->lock(&sinfo); android_memset16((uint16_t*)sinfo.bits, 0x07E0, sinfo.s*pfInfo.bytesPerPixel*sinfo.h); surface->unlockAndPost(); printf("memset 0x07E0 donen"); client->closeTransaction(); sleep(2); printf("setPosition...n"); client->openTransaction(); control->setPosition(100, 100); client->closeTransaction(); printf("setPosition donen"); sleep(2); // global transaction sometimes cannot trigger a redraw //client->closeGlobalTransaction(); printf("byen");炉挤仙挟
