我试图为我的片段创建一个适配器,但我明白了:
错误:(19,72)错误:不兼容的类型:android.app.FragmentManager无法转换为android.support.v4.app.FragmentManager
这是我主要活动的一部分:
import android.app.Activity;
import android.support.v4.view.ViewPager;
import android.os.Bundle;
public class MainActivity extends Activity {
CustomPagerAdapter mCustomPagerAdapter;
ViewPager mViewPager;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// == Setting up the ViewPager ==
mCustomPagerAdapter = new CustomPagerAdapter(getFragmentManager(),this); <--- Error is on this line
这是我的customAdapter类的一部分:
import android.content.Context;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;
public class CustomPagerAdapter extends FragmentPagerAdapter {
protected Context mContext;
public CustomPagerAdapter(FragmentManager fm, Context context) {
super(fm);
mContext = context;
}
我感谢任何帮助!

您需要在代码中使用SELECT
ct.Quote_Date, ht.Quote_Date AS htDate, ct.Quote_Price,
ht.Quote_Price AS [htPrice],
((ct.Quote_Price - ht.Quote_Price) / ht.Quote_Price) * 100 AS ChangePerc
FROM
#TempStock ct
LEFT JOIN
#TempStock ht ON CONVERT(DATE, CAST(ct.Quote_Date AS VARCHAR), 101) = DATEADD(MM, 1, CONVERT(DATE, CAST(ht.Quote_Date AS VARCHAR), 101))
ORDER BY
ct.Quote_Date DESC
,而不是getSupportFragmentManager()
。请参阅here原因

您的 FragmentPagerAdapter 属于android.support.v4.app.FragmentPagerAdapter
要么将其更改为android.app.FragmentPageAdapter
或更改此
mCustomPagerAdapter = new CustomPagerAdapter(getFragmentManager(),this);
到
mCustomPagerAdapter = new CustomPagerAdapter(getSupportFragmentManager(),this);
将解决您的问题干杯:)

您的MainActivity
应该延长FragmentActivity,您应该使用getSupportFragmentManager()
方法而不是getFragmentManager()
。
