遵循简短教程http://developer.android.com/training/graphics/opengl/environment.html#glsurfaceview。我的示例在模拟器中不起作用。我希望有一个基本的opengl示例在模拟器中工作,但它仍然是一个问题,甚至开发人员的指令都无法工作。

我有三个班级:

package com.test.flushrummy;

import android.opengl.GLSurfaceView;
import android.os.Bundle;
import android.app.Activity;

public class MainActivity extends Activity {

    private GLSurfaceView m_GlView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        m_GlView = new MyGLSurfaceView(this);
        setContentView(m_GlView);
    }

}

package com.test.flushrummy;

import javax.microedition.khronos.opengles.GL10;
import android.opengl.GLES20;
import android.opengl.GLSurfaceView.Renderer;

public class MyGLRenderer implements Renderer {

    public void onDrawFrame(GL10 unused) {
        // Redraw background color
        GLES20.glClear(GLES20.GL_COLOR_BUFFER_BIT);
    }

    public void onSurfaceChanged(GL10 unused, int width, int height) {
        GLES20.glViewport(0, 0, width, height);
    }

    @Override
    public void onSurfaceCreated(GL10 gl,
            javax.microedition.khronos.egl.EGLConfig config) {
        // TODO Auto-generated method stub
        GLES20.glClearColor(0.0f, 0.0f, 0.0f, 1.0f);
    }

}

package com.test.flushrummy;

import android.content.Context;
import android.opengl.GLSurfaceView;

class MyGLSurfaceView extends GLSurfaceView {

    public MyGLSurfaceView(Context context) {
        super(context);
        setRenderer(new MyGLRenderer());

        // Create an OpenGL ES 2.0 context
        setEGLContextClientVersion(2);

        // Render the view only when there is a change in the drawing data
        setRenderMode(GLSurfaceView.RENDERMODE_WHEN_DIRTY);
    }

}

我有我的证据。

<uses-sdk android:minSdkVersion="8" android:targetSdkVersion="19" />

project.properties:

target=android-19

“使用gpu host”在avd。

中被snabled

2 个答案:

答案 0 :(得分:1)

添加GPU仿真硬件属性,并在仿真中将其值设置为yes。添加它们并尝试它。

创建新虚拟设备时,有一个硬件部分。添加新的。有一个GPU模拟选项添加这个。

我遇到了同样的问题,这就是错误的,所以也可能是你的问题:

    protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    //COMMENT OUT THIS COMMAND
    //setContentView(R.layout.activity_main);

    /*if (savedInstanceState == null) {
        getFragmentManager().beginTransaction()
                .add(R.id.container, new PlaceholderFragment())
                .commit();
    }
    */
    //Setup surface view in this activity
    mView = new GLSurfaceView(this);
    mView.setEGLContextClientVersion(2);

    mView.setRenderer(new GraphicRenderer());
    mView.setRenderMode(GLSurfaceView.RENDERMODE_WHEN_DIRTY);
    setContentView(mView);

}

模板代码setContentView()需要注释掉。然后它在加载时不会崩溃。
