我创建了电子商务网站，但在购买时遇到了错误，因为当我现在购买商品时，支付集成工作正常，但出现错误。那么，如果我单击按钮及其打开的 fragment ，解决方案是什么。
ItemDetails.java(这是现在购买的代码，这里我也实现了一些 fragment 代码，但它不能正常工作)
public class ItemDetailsActivity extends AppCompatActivity {
int imagePosition;
String stringImageUri;
public static int notificationCountCart = 0;
TextView textViewshare, textViewmap;
private Fragment fragment;
@Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.main, menu);
//Show cart layout based on items
return true;
}
@Override
public boolean onPrepareOptionsMenu(Menu menu) {
// Get the notifications MenuItem and
// its LayerDrawable (layer-list)
MenuItem item = menu.findItem(R.id.action_cart);
NotificationCountSetClass.setAddToCart(ItemDetailsActivity.this, item, notificationCountCart);
// force the ActionBar to relayout its MenuItems.
// onCreateOptionsMenu(Menu) will be called again.
invalidateOptionsMenu();
return super.onPrepareOptionsMenu(menu);
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_search) {
startActivity(new Intent(ItemDetailsActivity.this, SearchResultActivity.class));
return true;
}else if (id == R.id.action_cart) {
/* NotificationCountSetClass.setAddToCart(MainActivity.this, item, notificationCount);
invalidateOptionsMenu();*/
startActivity(new Intent(ItemDetailsActivity.this, CartListActivity.class));
/* notificationCount=0;//clear notification count
invalidateOptionsMenu();*/
return true;
}else {
startActivity(new Intent(ItemDetailsActivity.this, EmptyActivity.class));

最佳答案
你必须尝试用 id 替换 Framelayout 是 fragment_container
当你尝试在不使用 FrameLayout 的情况下替换/添加 fragment 时，你应该使用 android.R.id.content，
所以请像这样替换你的代码。
FragmentManager fm = getSupportFragmentManager();
PayPalCheckoutActivity fragment = new PayPalCheckoutActivity();
fm.beginTransaction().replace(android.R.id.content,fragment).commit();
或
如果你使用 Framelayout 一旦检查你的 id R.id.fragment_container 是正确的。
关于java - 发生错误，应用程序在通过单击按钮打开 fragment 时崩溃，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/46463637/
