我按照了一个很好的教程.问题出在他们使用TextVIEws演示的教程中.我已经完成了活动(布局在 XML文件中).我想现在在滑块中使用这些活动,但看起来我只能使用VIEws.
我无法弄清楚如何更改类的代码(从“implements Activity”到“extends VIEw”),我可以在滑块中使用它.
我当前的代码如下所示:
public class HorizontalSlIDerBeispIElActivity extends Activity { public voID onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentVIEw(R.layout.main); cxt = this; awesomeAdapter = new AwesomePagerAdapter(); awesomePager = (VIEwPager) findVIEwByID(R.ID.awesomepager); awesomePager.setAdapter(awesomeAdapter); }... 然后使用PageAdapter的内部类:
...private class AwesomePagerAdapter extends PagerAdapter { public Object instantiateItem(VIEw collection,int position) { TextVIEw tv = new TextVIEw(cxt); tv.setText("Bonjour PAUG " + position); tv.setTextcolor(color.WHITE); tv.setTextSize(30); vIEw_01 = new submitCheatInstructions(cxt); ((VIEwPager) collection).addVIEw(tv,0); ((VIEwPager) collection).addVIEw(vIEw_01,1); return tv; }} 而不是TextVIEw“tv”我想使用ActivitIEs(即submitCheatInstructions).以前这个班看起来像:
public class submitCheatInstructions implements Activity {public voID onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentVIEw(R.layout.submitcheat_instructions);} }
但据我所知,我必须改变它
public class submitCheatInstructions extends VIEw { ????} 为了能够将它用于VIEwPager.
我现在的问题是我想将布局xml文件(submitcheat_instructions.xml)中的布局加载到该视图中,而不是在代码中执行所有 *** 作.我无法弄清楚我该怎么做.
谢谢你的帮助.
解决方法 我按照相同的教程和你一样,我最初无法实现这一点,但经过一些修补和试错后,下面的代码就像一个魅力:/** * Create the page for the given position. The adapter is responsible * for adding the vIEw to the container given here,although it only * must ensure this is done by the time it returns from * {@link #finishUpdate()}. * * @param container * The containing VIEw in which the page will be shown. * @param position * The page position to be instantiated. * @return Returns an Object representing the new page. This does not * need to be a VIEw,but can be some other container of the * page. */ @OverrIDe public Object instantiateItem(VIEw collection,int position) { VIEw v = new VIEw(PatIEntVIEw.this.getApplicationContext()); final LayoutInflater inflater = (LayoutInflater) PatIEntVIEw.this .getSystemService(Context.LAYOUT_INFLATER_SERVICE); switch (position) { case 0: v = inflater.inflate(R.layout.patIEntp1,(VIEwGroup) null,false); ((button) v.findVIEwByID(R.ID.pp1btnbck)).setonClickListener(new OnClickListener() { @OverrIDe public voID onClick(VIEw arg0) { finish(); } }); break; case 1: v = inflater.inflate(R.layout.patIEntp2,null,false ); break; default: TextVIEw tv = new TextVIEw(PatIEntVIEw.this.context); tv.setText("Page " + position); tv.setTextcolor(color.WHITE); tv.setTextSize(30); v = tv; break; } ((VIEwPager) collection).addVIEw(v,0); return v; } 希望这有帮助,祝你好运谢里夫·马祖克
