我在我的应用程序中获取此强制关闭错误,当我试图用DOM解析RSS时.但是并不总是强制问题...这是logcat:

我有一个尺寸为300*90的按钮图形.Hdpi/mdpi/ldpi的尺寸必须如何？谢谢

我有一个按钮,我想在按下时打开一个对话框.这是我的代码:

Button more = (Button) findViewById(R.id.more);
more.setOnClickListener(new View.OnClickListener() {
    public void onClick(View view) {
        //Intent myIntent = new Intent(view.getContext(), agones.class);
        //startActivityForResult(myIntent, 0);

        AlertDialog alertDialog = new AlertDialog.Builder(this).create();
        alertDialog.setTitle("hi");
        alertDialog.setMessage("this is my app");

        alertDialog.setButton("Continue..", new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int which) {
            // here you can add functions
        }
        });
    }
});

我在我的地图应用程序中有这个错误.你知道什么是错的吗？我已经检查过,包裹在我的.java文件中,并且我已将google地图的uses-libraries放入manifest.xml中的应用程序标签中..请帮助,我试着解决它...

我有一个listview,我想从我按下的每个列表项目中去一个新的活动.这是我的代码..

public class DialogActivity extends Activity {

 private ListView lv1;

 private String lv_arr[]={"SuperLeague 2010-2011","Olympiakos on YouTube","Olympiakos Web Site","Find Karaiskaki on map","Reserve Tickets"};
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(R.layout.dialog);

        lv1=(ListView)findViewById(R.id.dialog_list);

        // By using setAdpater method in listview we an add string array in list.

        lv1.setAdapter(new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1 , lv_arr));


        lv1.setOnItemClickListener(new OnItemClickListener() {
      public void onItemClick(AdapterView<?> parent, View view,
          int position, long id) {

      //  Intent newActivity = new Intent(view.getContext(),agones.class);     
            // …

如果我的float变量设置为0,我的代码工作,但如果我的变量为null,我希望我的代码工作.我怎么能这样做？这是我写的代码片段:

float oikonomia= (float)((float)new Float(vprosvasis7.getText().toString()));

                         if(oikonomia==0){

我已经追平if(oikonomia==null)或if(oikonomia=null),但它无法正常工作.

PS:另一种方式是初始设置oikonomia=0;,如果用户更改它,请转到我的if会话.这也不起作用.

Float oikonomia = Float.valueOf(vprosvasis7.getText().toString());

                     if(oikonomia.toString() == " "){



float oikonomia= (float)((float)new Float(vprosvasis7.getText().toString()));
                  oikonomia=0;
                         if(oikonomia==0){

这种方式也不起作用:

Float oikonomia = Float.valueOf(vprosvasis7.getText().toString());

                         if(oikonomia.toString() == " "){

我有像Android市场一样的水平滚动页面(ViewPager).

我的问题是我想在其中有一些水平滚动视图和一些图像？这可能吗？

就像现在一样,我在我的视图中得到一个小滚动,然后整个页面滚动.

谢谢你的时间!

我希望我的位图位于我的屏幕中心..我试着这样但它不起作用......

Bitmap myBitmap = BitmapFactory.decodeResource(getResources(), R.drawable.compass);

            int w = canvas.getWidth();
            int h = canvas.getHeight();

            int bw=myBitmap.getWidth();
            int bh=myBitmap.getHeight();

            int cx = w / 2;
            int cy = h / 2;

            Display d = getWindowManager().getDefaultDisplay();
            int x = d.getWidth();
            int y = d.getHeight();
            int dx = x / 2;
            int dw = y /2;
            canvas.translate(cx, cy);    
            if (mValues != null) {
                canvas.rotate(-mValues[0]);
            }  

            int centreX = (x  - bw) /2;

                int centreY = (cy - bh) /2;  
            //canvas.drawPath(mPath, mPaint);
            canvas.drawBitmap(myBitmap, centreX,centreY, …

我有一个基于Android-ViewPagerIndicator的应用程序.

我想创建HorizontalScrollView一个Fragment.视图将包含一些图片.我的问题是,当我尝试滚动时,我的滚动视图不起作用,我滚动所有片段而不仅仅是我想要的视图.希望我的问题是可以理解的!:)

这是代码的一部分:

.XML

   <HorizontalScrollView android:id="@+id/horizontalScroll"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content" 
    android:scrollbars="none" 
    android:fadingEdgeLength="10dp">
<LinearLayout 
        android:id="@+id/harokLayout"
        android:background="#EEEEEE"
        android:orientation="horizontal"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content">

        <ImageView android:src="@drawable/app2" android:layout_height="wrap_content" android:layout_width="wrap_content" />
        <ImageView android:src="@drawable/app1" android:layout_height="wrap_content" android:layout_width="wrap_content" />
        <ImageView android:src="@drawable/app2" android:layout_height="wrap_content" android:layout_width="wrap_content" />
        <ImageView android:src="@drawable/app1" android:layout_height="wrap_content" android:layout_width="wrap_content" />
        <ImageView android:src="@drawable/app2" android:layout_height="wrap_content" android:layout_width="wrap_content" />
        <ImageView android:src="@drawable/app1" android:layout_height="wrap_content" android:layout_width="wrap_content" />
        <ImageView android:src="@drawable/app2" android:layout_height="wrap_content" android:layout_width="wrap_content" />
        <ImageView android:src="@drawable/app1" android:layout_height="wrap_content" android:layout_width="wrap_content" />
        <ImageView android:src="@drawable/app2" android:layout_height="wrap_content" android:layout_width="wrap_content" />
        <ImageView android:src="@drawable/app1" android:layout_height="wrap_content" android:layout_width="wrap_content" />
        <ImageView android:src="@drawable/app2" android:layout_height="wrap_content" android:layout_width="wrap_content" />
        <ImageView android:src="@drawable/app1" android:layout_height="wrap_content" …

我的列表项之间有一些水平黑线.我怎么擦除它们？我的图形没有部分.谢谢
