当运行简单的代码在SurfaceView中绘制时,我在Android模拟器中得到了几个SurfaceView错误。因此,在模拟器中运行时,SurfaceView不会绘制。相同的代码在设备上正确运行(在本例中,是Amazon 8 (2017 - KFDOWI))。
以下是错误:
模拟器: android/android-emugl/host/libs/Translator/GLES_V2/GLESv2Imp.cpp:glReadPixels:2827错误0x502 模拟器: sPrepareTexImage2D:3087失败验证 模拟器: android/android-emugl/host/libs/Translator/GLES_V2/GLESv2Imp.cpp:glTexImage2D:3133错误0x500 模拟器: sPrepareTexImage2D:3087失败验证 模拟器: android/android-emugl/host/libs/Translator/GLES_V2/GLESv2Imp.cpp:glTexImage2D:3133错误0x500 模拟器: android/android-emugl/host/libs/Translator/GLES_V2/GLESv2Imp.cpp:glTexSubImage2D:3237错误0x500
以下是代码:
import android.content.Context;
import android.graphics.Canvas;
import android.graphics.Color;
import android.util.AttributeSet;
import android.view.SurfaceHolder;
import android.view.SurfaceView;
public class CustomSurfaceView extends SurfaceView implements SurfaceHolder.Callback {
private SurfaceHolder surfaceHolder;
public CustomSurfaceView(Context context) {
super(context);
init();
}
public CustomSurfaceView(Context context, AttributeSet attributeSet) {
super(context, attributeSet);
init();
}
private void init() {
this.surfaceHolder = getHolder();
surfaceHolder.addCallback(this);
}
@Override
public void surfaceCreated(SurfaceHolder surfaceHolder) {
Canvas canvas = surfaceHolder.lockCanvas();
canvas.drawColor(Color.RED);
surfaceHolder.unlockCanvasAndPost(canvas);
}
@Override
public void surfaceChanged(SurfaceHolder surfaceHolder, int i, int i1, int i2) {
}
@Override
public void surfaceDestroyed(SurfaceHolder surfaceHolder) {
}
}活动:

此外,我可以在同一个模拟器中运行OpenGL es2.0代码,而不会出现这些问题。

停止硬件加速。
打开虚拟设备配置->编辑虚拟设备->使用软件模式图形
