Question

我编写了一个在运行时生成库的方法。

private Gallery createGallery(ImageAdapter imageAdapter) {

    Gallery sampleGallery = new Gallery(getApplicationContext());
    sampleGallery.setLayoutParams(new ViewGroup.LayoutParams(
            ViewGroup.LayoutParams.FILL_PARENT,
            ViewGroup.LayoutParams.WRAP_CONTENT));
    sampleGallery.setGravity(Gravity.FILL_VERTICAL);
    sampleGallery.setSpacing(5);
    sampleGallery.setAdapter(imageAdapter);
    sampleGallery.setSelection(1);
    return sampleGallery;

}

然后我创建一个厨房并尝试将其设置为标签布局。

final TabHost mTabHost = (TabHost) findViewById(R.id.tabHost);
    mTabHost.setup();
    Gallery tabGallery = createGallery(brkingNewAdapter); // my image adapter
    tabGallery.setId(R.id.gallery_1);
    mTabHost.addTab(mTabHost.newTabSpec("tab_test1").setIndicator("TAB 1")
            .setContent(R.id.gallery_1));

R.id.gallery_1 在here中被定义为提及。

我得到如下例外。

无法创建标签内容，因为无法找到ID为2130968576的视图

对此有何帮助？

提前谢谢。

你应该看看TabContentFactory。

您的解决方案是实施TabContentFactory并在Gallery方法中返回createTabContent个实例，并在setContent(TabHost.TabContentFactory contentFactory)中使用addTab方法。

class GalleryContentFactory implements TabContentFactory{
    private ImageAdapter imageAdapter;
    public GalleryContentFactory(ImageAdapter imageAdapter){
        this.imageAdapter = imageAdapter;
    }
    public View createTabContent(String tag){
        Gallery sampleGallery = new Gallery(getApplicationContext());
        sampleGallery.setLayoutParams(new ViewGroup.LayoutParams(
            ViewGroup.LayoutParams.FILL_PARENT,
            ViewGroup.LayoutParams.WRAP_CONTENT));
        sampleGallery.setGravity(Gravity.FILL_VERTICAL);
        sampleGallery.setSpacing(5);
        sampleGallery.setAdapter(imageAdapter);
        sampleGallery.setSelection(1);
        return sampleGallery;
    }
}

并添加到标签：

GalleryContentFactory galleryFactory = new GalleryContentFactory(brkingNewAdapter);
mTabHost.addTab(mTabHost.newTabSpec("tab_test2").setIndicator("TAB 2")
            .setContent(galleryFactory));

如何将以编程方式生成的库添加到选项卡布局？
