ViewPager滑動到下一頁當imageView onclick

Question

我有一個ViewPager幻燈片到下一頁當imageView onclick 目前，我有2頁的ViewPager，並且他們每個都有不同的佈局 我在first_frag上做了一個按鈕。 xml，並嘗試將onClick監聽器設置爲FirstFragment類，但它不起作用，有什麼幫助？下面附上我來源：

MainActivity.java

public class MainActivity extends FragmentActivity { 
public ViewPager pager; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main);  
    ViewPager pager = (ViewPager) findViewById(R.id.viewPager); 
    pager.setAdapter(new MyPagerAdapter(getSupportFragmentManager())); 

} 

private class MyPagerAdapter extends FragmentPagerAdapter { 

    public MyPagerAdapter(FragmentManager fm) { 
     super(fm); 
    } 

    @Override 
    public Fragment getItem(int pos) { 
     switch(pos) { 

     case 0: return FirstFragment.newInstance("First Page"); 
     case 1: return SecondFragment.newInstance("Second Page"); 
     default: return FirstFragment.newInstance("Default"); 
     } 
    } 

    @Override 
    public int getCount() { 
     return 2; 
    }  
} 
}

FirstFragment.java

public class FirstFragment extends Fragment{ 

@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { 
    View v = inflater.inflate(R.layout.first_frag, container, false); 

    TextView tv = (TextView) v.findViewById(R.id.tvFragFirst); 
    tv.setText(getArguments().getString("msg")); 
    return v; 

} 


public static FirstFragment newInstance(String text) { 

    FirstFragment f = new FirstFragment(); 
    Bundle b = new Bundle(); 
    b.putString("msg", text); 

    f.setArguments(b); 
    return f; 

}

SecondFragment.java

public class SecondFragment extends Fragment { 

@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { 
View v = inflater.inflate(R.layout.second_frag, container, false); 

TextView tv = (TextView) v.findViewById(R.id.tvFragSecond); 
tv.setText(getArguments().getString("msg")); 


return v; 
} 

public static SecondFragment newInstance(String text) { 

SecondFragment f = new SecondFragment(); 
Bundle b = new Bundle(); 
b.putString("msg", text); 

f.setArguments(b); 

return f; 

}

// 片段1：

View v; 
@Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { 

v = inflater.inflate(R.layout.second_frag, container, false); 

TextView tv = (TextView) v.findViewById(R.id.tvFragSecond); 
tv.setText(getArguments().getString("msg")); 

@Override 
public void onActivityCreated(Bundle savedInstanceState) { 
    super.onActivityCreated(savedInstanceState); 
      ImageView iv = (ImageView) v.findViewById(R.id.thisButton); 
      iv.setOnClickListener(new OnClickListener(){ 
         public void onClick(View v) { 
      MainActivity mActivity = (MainActivity) getActivity(): 
      mActivity.changeFragment(); 

       } 
      }); 
} 

MainActivity

public void changeFragment(){ 
pager.setCurrentItem(1); 
} 

我所做的是：

• 硒t片段中的imageView的偵聽器onCreateView
• 向主活動添加一個名爲changeFragment的公共方法，該方法設置當前的viewPager項目。
• 從偵聽器調用此方法。
