android从所有片段选项卡获取价值

我已经声明了framgmentActivity,如下所示：

    mTabHost = (FragmentTabHost) findViewById(android.R.id.tabhost);
    mTabHost.setup(this, getSupportFragmentManager(), R.id.realtabcontent);
    mTabHost.addTab(mTabHost.newTabSpec("basic").setIndicator("Basic",getResources().getDrawable(R.drawable.ic_launcher)),BasicProductFragment.class, null);
    mTabHost.addTab(mTabHost.newTabSpec("taxes").setIndicator("Taxes",getResources().getDrawable(R.drawable.ic_launcher)),TaxesProductFragment.class, null);
    mTabHost.addTab(mTabHost.newTabSpec("price").setIndicator("Price",getResources().getDrawable(R.drawable.ic_launcher)),PriceProductFragment.class, null);
    mTabHost.addTab(mTabHost.newTabSpec("stock").setIndicator("Stock",getResources().getDrawable(R.drawable.ic_launcher)),StockProductFragment.class, null);

现在,在所有frament中,我现在已经在此活动中声明了两个或三个edittext,我想从不同的fragment选项卡中从所有edittext中获取数据.

解决方法:

单例课程可以帮助解决您的问题.

public class GlobalApp {
    private static GlobalApp instance = new GlobalApp();

    private GlobalApp() {}

    public static GlobalApp getInstance() {
        return instance;
    }

    public Details details = new Details ();

}

然后像这样在您的Fragment类中使用.

GlobalApp.getInstance().details.setSomeData("something");

现在,您可以在mainActivity中获取所有在这些片段中更改的值

 GlobalApp.getInstance().details.getSomeData();

对于另一个与此相关的问题,我给出了相同的答案.
