我正在尝试在android中生成自定义tabVIEw

AndroidTabRestaurantDescListVIEw.java

public class AndroIDTabRestaurantDescListVIEw extends tabactivity {    // TabSpec names        private static final String INBox_SPEC = "rating";        private static final String OUTBox_SPEC = "Price";        private static final String PROfile_SPEC = "distance";        private TabHost Photos;        @OverrIDe        public voID onCreate(Bundle savedInstanceState) {            super.onCreate(savedInstanceState);            setContentVIEw(R.layout.main);            Photos=(TabHost) findVIEwByID(R.ID.Photobutton);             TabHost tabHost = getTabHost();            Photos.getTabWidget().setdivIDerDrawable(R.drawable.tab_divIDer);            // InBox Tab            TabSpec inBoxSpec = tabHost.newTabSpec(INBox_SPEC);            Intent inBoxIntent = new Intent(this, MainActivity.class);            inBoxSpec.setIndicator(INBox_SPEC);            // Tab Content            inBoxSpec.setContent(inBoxIntent);            // OutBox Tab            TabSpec PriceSpec = tabHost.newTabSpec(OUTBox_SPEC);            Intent PriceIntent = new Intent(this, PriceDescriptionActivity.class);            PriceSpec .setIndicator(OUTBox_SPEC);            PriceSpec.setContent(PriceIntent);            // Profile Tab            TabSpec distanceSpec = tabHost.newTabSpec(PROfile_SPEC);            Intent distanceIntent = new Intent(this, distancediscriptionActivity.class);            distanceSpec .setIndicator(PROfile_SPEC);             distanceSpec.setContent(distanceIntent);            // Adding all TabSpec to TabHost            tabHost.addTab(inBoxSpec);             tabHost.addTab(PriceSpec);             tabHost.addTab(distanceSpec);             //Set the current value tab to default first tab            tabHost.setCurrentTab(0);            //Setting custom height for the tabs            final int height = 45;            tabHost.getTabWidget().getChildAt(0).getLayoutParams().height = height;            tabHost.getTabWidget().getChildAt(1).getLayoutParams().height = height;            tabHost.getTabWidget().getChildAt(2).getLayoutParams().height = height;            Photos.setonClickListener(new OnClickListener() {                public voID onClick(VIEw v) {                    Intent PhotoIntent = new Intent(AndroIDTabRestaurantDescListVIEw.this, AndroIDTabRestaurantDescImageListVIEw.class);                    startActivity(PhotoIntent);                             }            });        }}

解决此问题的任何输入
谢谢

解决方法:

问题在这一行：

Photos=(TabHost) findVIEwByID(R.ID.Photobutton);

我假设R.ID.Photobutton是一个button,并且您试图将其强制转换为TabHost,但是您不能这样做.

一切基本上都在您的日志中可见.这两行最相关：
