希望我能做一个测试来验证互联网连接,我不想检查网络状态,因为它只检测我是否在我的设备上激活了互联网,y yo quiero revisar si es posible conectarse a internet.像ping一样的东西.

我在AndEngine练习.我做了一个背景,一个精灵,并增加了运动和重力.

所以我决定练习背景音乐和声音,但我有一个问题.现在,当我启动应用程序时,我得到黑屏,精灵失真,当然音乐不响.

你能帮我吗？这是代码:

public class MainActivity extends BaseGameActivity {
    Scene scene;
    private Music music;
    protected static final int CAMERA_WIDTH = 850;
    protected static final int CAMERA_HEIGHT = 480;
    BitmapTextureAtlas playerTexture;
    ITextureRegion playerTexureRegion;
    PhysicsWorld physicsWorld;



    @Override
    public EngineOptions onCreateEngineOptions() {
        // TODO Auto-generated method stub

         Camera mCamera = new Camera(0, 0, CAMERA_WIDTH, CAMERA_HEIGHT);

        EngineOptions options = new EngineOptions(true,
                ScreenOrientation.LANDSCAPE_FIXED, new FillResolutionPolicy(), mCamera);
        return options;
    }

    @Override
    public void onCreateResources(
            OnCreateResourcesCallback pOnCreateResourcesCallback)
            throws Exception {
        // TODO Auto-generated method stub


         loadGfx();
         loadSounds(); …

我正在做一个动态textview的例子,它是通过按下按钮创建的.它们的创建格式类似于:

1- Textview (fist created)
2- TextView
3- TextView (last created)

我想知道我们是否可以按升序创建它们,一个高于之前的TextView.这样的事情:

3- TextView (last created)
2- TextView
1- TextView (first created)

这是我的示例代码:

 private OnClickListener onClick() {
     return new OnClickListener() {

         @Override
         public void onClick(View v) {
             mLayout.addView(createNewTextView("TextView"));
             count = count +1;
         }
     };
 }

 private TextView createNewTextView(String text) {
     final LayoutParams lparams = new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
     final TextView textView = new TextView(this);
     textView.setLayoutParams(lparams);
     textView.setText(count+ "- " + text);
     textView.setTextSize(TypedValue.COMPLEX_UNIT_SP, 18);
     return textView;
 }}
