努力創造在Android Studio中一ListView片段並獲得錯誤

無法解析方法show（android.support.v4.app FragmentManager，java.lang.string）

錯誤是在p.show(fm,"Players Fragment)紅色下劃線，試圖解決這個問題，但無處可去，我真的很感激這個解決方案！謝謝

import android.os.Bundle; 
import android.support.v4.app.FragmentActivity; 
import android.support.v4.app.FragmentManager; 
import android.view.View; 
import android.widget.Button; 




public class MainActivity extends FragmentActivity { 

    Button showBtn; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 

     final FragmentManager fm =getSupportFragmentManager(); 
     final PlayersFragment p=new PlayersFragment(); 

     showBtn=(Button)findViewById(R.id.button1); 
     showBtn.setOnClickListener(new View.OnClickListener() { 

      @Override 
      public void onClick(View view) { 
       p.show(fm,"Players Fragment"); //error is here 
      } 

     }); 
    } 
}

是'PlayersFragment'的'DialogFragment'的子類？ – Blackbelt

加上'PlayersFragment'代碼 – Rustam

喜，是PlayersFragment是DialogFragment – james

我想你正在使用android.app.DialogFragment而不是android.support.v4.app.DialogFragment。只需從支持庫的android.support.v4.app.DialogFragment延伸PlayersFragment即可。或者，如果你的目標不是舊設備，你可以改變getSupportFragmentManager()到getFragmentManager()

的PlayersFragment類我沒有嘗試改變getSupportFragmentManager到getFragmentManager但拋出一個錯誤太 – james

我伸出PlayersFragment到類android.support。 v4.app.DialogFragment像你說的Semyon Danilov，這已經解決了我的問題非常感謝你 – james

@james很高興我可以幫助:) –

你必須在類PlayersFragment導入android.support.v4.app.DialogFragment，然後更改getSupportFragmentManager()到getFragmentManager()。
