Question

我一直在尝试将数据库中的记录列表加载到屏幕上，但是当应用获取数据并尝试在屏幕上显示时，似乎存在问题。我读到有时这种类型的错误在显示大图像时会抛出，但我没有图像，并尝试了一些其他我已经读过的解决方案。任何意见都表示赞赏！

这是我试图“膨胀”的布局的xml。

由于我不确定错误发生在哪里，我不确定要发布什么代码 - 而且我不想让它变得不可读。

Answer 1

目前您将?android:attr/textAppearanceMedium设为android:textSize 您应该使用android:textAppearance替换该属性。

更改

android:textSize="?android:attr/textAppearanceMedium"

TO

android:textAppearance="?android:attr/textAppearanceMedium"

OR

将直接值设置为android:textSize，如

android:textSize="10sp"

Answer 2

android:theme="@style/ThemeOverlay.AppCompat.Dark"

我从我的xml文件中删除了我的问题已解决

Answer 4

您似乎正在Exception获得<TextView/>下方的android:textSize="?android:attr/textAppearanceMedium"。

android:textAppearance="?android:attr/textAppearanceMedium"

尝试

string replyText = "I am not yet ready to answer this question. Please choose another option.";

            switch (appointmentBookType){
                case Option1:
                    //Call Option1 Dialog.
                    break;
                case Option2:
                    //Call Option2 Dialog.
                    break;

Answer 5

private void getDetailFood(String foodId) {
foods.child(foodId).addValueEventListener(new ValueEventListener() {
@Override
public void onDataChange(DataSnapshot dataSnapshot) {
try {
Food food = dataSnapshot.getValue(Food.class);
**Picasso.with(getBaseContext()).load(food.getImage())
                        .into(foodd_image);**
(Iam getting NullPOinter Exception)`enter code here`
collapsingToolbarLayout.setTitle(food.getName());
food_price.setText(food.getPrice());
food_description.setText(food.getDescription());
food_name.setText(food.getName());
}
catch (Exception e)
{
e.printStackTrace();
}

}
