错误: 找不到符号方法集内容视图(整数)

我对Android Studio很陌生。我在setContentView有问题。 我知道它在片段中不起作用。

有人知道如何解决这个问题吗？

错误：

法典：

public class Tab1Fragment extends Fragment{
private static final String TAG = "Tab1Fragment";

Toolbar mToolbar;
ListView mListView;
String[] countryNames = {"Australia", "Brazil", "China", "France", "Germany", "India", "Ireland", "Italy"
, "Mexico", "Poland", "Russia", "Spain", "US"};
int[] countryFlags = {R.drawable.flag_australia,
R.drawable.flag_brazil,
R.drawable.flag_china,
R.drawable.flag_france,
R.drawable.flag_germany,
R.drawable.flag_india,
R.drawable.flag_ireland,
R.drawable.flag_italy,
R.drawable.flag_maxico,
R.drawable.flag_poland,
R.drawable.flag_russia,
R.drawable.flag_spain,
R.drawable.flag_us};

public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.fragment1_layout);
mToolbar = (Toolbar) findViewById(R.id.toolbar);
mToolbar.setTitle("My Application");
mListView = (ListView) findViewById(R.id.listview);
MyAdapter myAdapter = new MyAdapter(Tab1Fragment.this, countryNames, countryFlags);
mListView.setAdapter(myAdapter);
mListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
Intent mIntent = new Intent(Tab1Fragment.this, DetailActivity.class);
mIntent.putExtra("countryName", countryNames[i]);
mIntent.putExtra("countryFlag", countryFlags[i]);
startActivity(mIntent);
}
});
}
private Button btnTEST;
}

在片段中，您膨胀布局而不是setContentView代码可能看起来像这样

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment1_layout, container, false);
// Put your fragment code here
return rootView;
}
