那不是我。但也許它有太多的代碼和......除了標題之外沒有任何描述。 – Mauker

@Mauker無需描述，當我通過findviewbyid設置glsurfaceview時，我得到了nullpointerexception – Dauezevy

您是否在'setContentView'方法中使用了正確的引用？ – Mauker

首先，不要使用fill_parent，它已被棄用。改爲使用match_parent。

現在您的代碼，試圖改變這一點：

GPUImage mGPUImage = new GPUImage(this); 
mGPUImage.setGLSurfaceView((GLSurfaceView) findViewById(R.id.effectsview));

要這樣：

GPUImage mGPUImage = new GPUImage(this); 
GLSurfaceView glView = (GLSurfaceView) this.findViewById(R.id.effectsview); 
glView.setRenderer(this); // "this" refers to a renderer. I'm assuming your class implements it. 
mGPUImage.setGLSurfaceView(glView);
