Android 报错 android.view.InflateException: Binary XML file line #7: Binary XML file line #7: Error inflating class com.coolweather.android.fragment
我在学习安卓开发中的碎片（Fragment）时遇到的报错，特此记录下来，其实问题很简单，下面是会产生报错的java代码和xml代码：
package com.example.ui_test; import android.annotation.SuppressLint; import android.os.Bundle; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.widget.TextView; import androidx.annotation.NonNull; import androidx.annotation.Nullable; import androidx.fragment.app.Fragment; @SuppressLint("ValidFragment") class NewsContentFragment extends Fragment { private View view; @Nullable @Override public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) { view = inflater.inflate(R.layout.news_content_frag,container,false); return view; } public void refresh(String newsTitle,String newsContent){ View visibilityLayout = view.findViewById(R.id.visibility_layout); visibilityLayout.setVisibility(View.VISIBLE); TextView newsTitleText = (TextView) view.findViewById(R.id.news_title); TextView newsContentText = (TextView) view.findViewById(R.id.news_content); newsTitleText.setText(newsTitle); newsContentText.setText(newsContent); } }
下面是修改后的java代码：
package com.example.ui_test; import android.annotation.SuppressLint; import android.os.Bundle; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.widget.TextView; import androidx.annotation.NonNull; import androidx.annotation.Nullable; import androidx.fragment.app.Fragment; @SuppressLint("ValidFragment") public class NewsContentFragment extends Fragment { private View view; @Nullable @Override public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) { view = inflater.inflate(R.layout.news_content_frag,container,false); return view; } public void refresh(String newsTitle,String newsContent){ View visibilityLayout = view.findViewById(R.id.visibility_layout); visibilityLayout.setVisibility(View.VISIBLE); TextView newsTitleText = (TextView) view.findViewById(R.id.news_title); TextView newsContentText = (TextView) view.findViewById(R.id.news_content); newsTitleText.setText(newsTitle); newsContentText.setText(newsContent); } } 仅仅是因为定义java类时没有写public，xml文件无需修改。
