Question

我写了一个简单的Android应用程序来为屏幕绘制颜色。但是每次编译它都会崩溃。

这是我的代码

public class MainActivity extends ActionBarActivity {

GLSurfaceView glSurfaceView;
MyRenderer renderer = new MyRenderer();;

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

    glSurfaceView = new GLSurfaceView(this);
    glSurfaceView.setRenderer(renderer);
    setContentView(glSurfaceView);
}

}

和

public class MyRenderer  implements GLSurfaceView.Renderer{
@Override
public void onSurfaceCreated(GL10 gl, EGLConfig config) {
    gl.glClearColor(0f, 1f, 0f, 1f);
}

@Override
public void onSurfaceChanged(GL10 gl, int width, int height) {

}

@Override
public void onDrawFrame(GL10 gl) {
    gl.glClear(GL10.GL_COLOR_BUFFER_BIT);
}

}

Logcat屏幕

我尝试了一些解决方案，但它不起作用我的程序有问题吗？

Answer 1

我尝试了你的代码，我发现它有效。我做了一些小改动。在下面找到我的代码 MainActivity.Java

package com.example.opengl;

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

public class MainActivity extends Activity {

    GLSurfaceView glSurfaceView;
    MyRenderer renderer = new MyRenderer();

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        glSurfaceView = new GLSurfaceView(this);
        glSurfaceView.setRenderer(renderer);
        setContentView(glSurfaceView);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

}

MyRenderer.java

package com.example.opengl;
import javax.microedition.khronos.egl.EGLConfig;
import javax.microedition.khronos.opengles.GL10;

import android.opengl.GLSurfaceView;

public class MyRenderer implements android.opengl.GLSurfaceView.Renderer{

    @Override
    public void onDrawFrame(GL10 gl) {
        // TODO Auto-generated method stub
        gl.glClearColor(0f, 1f, 0f, 1f);
    }

    @Override
    public void onSurfaceChanged(GL10 gl, int width, int height) {
        // TODO Auto-generated method stub

    }

    @Override
    public void onSurfaceCreated(GL10 gl, EGLConfig config) {
        // TODO Auto-generated method stub
        gl.glClear(GL10.GL_COLOR_BUFFER_BIT);
    }



}

的AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.opengl"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="16"
        android:targetSdkVersion="18" />

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name="com.example.opengl.MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>
