如何添加程序生成的画廊标签布局？ [英] How to add programmatically generated gallery to tab layout?

问题描述

我写信给在运行时生成库的方法。

I write a method to generate gallery at run time.

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，我创建了一个厨房，并尝试将其设置为一个标签布局。

Then I create a galley and try to set it to a Tab Layout.

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 被定义为中提到的here.

我得到一个例外如下：

无法创建选项卡的内容，因为找不到视图ID为2130968576

Could not create tab content because could not find view with id 2130968576

任何帮助？

感谢您提前。

推荐答案

您应该看一看的 TabContentFactory 。

您的解决方案是实施 TabContentFactory ，并在图库实例> createTabContent 方法和使用 setContent（TabHost.TabContentFactory contentFactory）方法 addTab 。

The solution for you would be to implement TabContentFactory and return the Gallery instance in the createTabContent method and use setContent(TabHost.TabContentFactory contentFactory) method in addTab.

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;
    }
}

和添加到标签：

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