小编Ren*_*ith的帖子

当您通过Google Play安装应用时,会在主屏幕上创建应用的快捷方式.用户可以通过禁用Google Play应用中的"自动添加小工具"设置来阻止这种情况发生.

从开发人员的角度来看,我想知道是否可以在我自己的应用程序中阻止这种情况.是否有明确的设置或其他告诉Google不要在安装时为我的应用创建图标？

没有Launcher Activity不是我的应用程序的选项.

我试过这个片段,但它不起作用

try 
    {
    Integer.parseInt(enteredID.getText().toString());
    Log.i("enteredID value", "enterdID is numeric!!!!!!!!!!!^^^");
    flag=1;
} catch (NumberFormatException e) {
    flag=-1;
    Log.i("enteredID value", "enterdID isn't numeric!!!!!!!!!!!^^^");
}

注意它可以接受用户名或ID来检查值,我不希望它只接受数字!

当我在我的本地主机中尝试时,它可以找到.这是我的localhost提供的JSON.

当我ImageView在屏幕上移动时,第一次一切都很好,但是第二次ImageView没有正常移动.

这就是我到目前为止所做的.

img.setOnTouchListener(new View.OnTouchListener() {
    @Override
    public boolean onTouch(View v, MotionEvent event) {
        // TODO Auto-generated method stub
        int eid = event.getAction();
        switch (eid) {
            case MotionEvent.ACTION_MOVE:
                FrameLayout.LayoutParams mParams = (FrameLayout.LayoutParams) img.getLayoutParams();
                int x = (int) event.getRawX();
                int y = (int) event.getRawY();
                mParams.leftMargin = x-50;
                mParams.topMargin = y-50; 
                img.setLayoutParams(mParams);
                break;
            case MotionEvent.ACTION_DOWN:
                x1=img.getX();
                y1=img.getY(); 
                break;                         
            case MotionEvent.ACTION_UP:
                img.setX(x1);
                img.setY(y1);                          
                break; 
            default:
                break;
            }
        return true;
    }
});

我正在使用Eclipse.对于7英寸和10英寸平板电脑来说,获得模拟器的最佳方法是什么？

public class XMLParser {

    }


    public String getXmlFromUrl(String url) {
        String responseBody = null;

        String d = d1.getData(); // text
        String y = d1.getYear(); // year
        String c = d1.getCircular();
        String p = d1.getPage();

        List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
        nameValuePairs.add(new BasicNameValuePair("YearID", y));

        nameValuePairs.add(new BasicNameValuePair("CircularNo", c));

        nameValuePairs.add(new BasicNameValuePair("SearchText", d));

我真的很痛苦这个问题.我已经设置了旗帜android:configChanges="keyboardHidden|orientation|locale"

但是当我改变语言的配置时,onconfigurationchanged不会调用函数.奇怪的是,我的代码在其他Android平台上运行良好.

我在这里搜索了这个问题.有人说我需要将sdk版本设置得更低.但它没有用.

请给我一些提示.

你会认为会有一个直接的解决方案.Android文档说明:

方向传感器在Android 2.2(API级别8)中已弃用.我们建议您将getRotationMatrix()方法与getOrientation()方法结合使用以计算方向值,而不是使用方向传感器中的原始数据.

然而,他们没有提供如何实施getOrientation()和实施的解决方案getRotationMatrix().我花了几个小时在这里阅读使用这些方法的开发人员的帖子,但他们都有部分粘贴的代码或一些奇怪的实现.谷歌搜索没有提供教程.有人可以使用这两种方法粘贴一个简单的解决方案来生成方向吗？

我的应用程序在标准手机上运行,​​但它也运行在Android播放器上,我通过HDMI连接到我的电视,并使用鼠标进行导航.有没有办法以编程方式确定设备是否具有触摸屏支持,以便我可以区分这两种导航方式？

我尝试过这个,但它在两个设备上都返回true:

getPackageManager().hasSystemFeature("android.hardware.touchscreen");
