OnClick按钮导航到仪表板而不是新片段

Question

我的Android应用程序中存在设备特定问题。图标图标onclick一个新的片段应该加载，但它导航到仪表板。它在除三星duos设备之外的所有其他设备上都能正常工作。

@Override
public void onClick(View v)
{
    switch (v.getId())
    {
        case R.id.add_deal:
            Intent addDealIntent = new Intent(mContext, BaseFragmentActivity.class);
            addDealIntent.putExtra("Merchant", merchantInfo);
            addDealIntent.putExtra("FragmentClassName", AddDealFragment.class.getName());
            addDealIntent.putExtra("toolbarTitle", "Add Deal");
            mContext.startActivity(addDealIntent);
            break;
        case R.id.add_product:
            Intent addProductIntent = new Intent(mContext, BaseFragmentActivity.class);
            addProductIntent.putExtra("Merchant", merchantInfo);
            addProductIntent.putExtra("Categories", mMerchantCategories);
            addProductIntent.putExtra("SubCategories", mMerchantSubCategories);
            addProductIntent.putExtra("SubSubCategories", mMerchantSubSubCategories);
            addProductIntent.putExtra("SuperSubCategories", mMerchantSuperSubCategories);
            addProductIntent.putExtra("FragmentClassName", AddProductFragment.class.getName());
            addProductIntent.putExtra("toolbarTitle", "Add Product");
            mContext.startActivity(addProductIntent);
            break;
        case R.id.dialog_button_cancel:
            dismiss();
            break;
        default:
            break;
    }
     dismiss();
}

使用startActivity方法，您只能在activitis之间导航，然后您必须更改片段。

您可以使用此代码更改您的片段：

// Create new fragment and transaction
Fragment newFragment = new ExampleFragment();
FragmentTransaction transaction = getFragmentManager().beginTransaction();

// Replace whatever is in the fragment_container view with this fragment,
// and add the transaction to the back stack if needed
transaction.replace(R.id.fragment_container, newFragment);
transaction.addToBackStack(null);

// Commit the transaction
transaction.commit();
