public class MainActivity extends AppCompatActivity implements 
View.OnClickListener { 
ListView listView; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar); 
    setSupportActionBar(toolbar); 

    Button btnSimpleTabs = (Button) findViewById(R.id.scrollingTabs); 

    btnSimpleTabs.setOnClickListener(this); 
    listView = (ListView) findViewById(R.id.listView1); 
    String[] values = new String[]{ 
      "Fragment 1 ::", 
      "Fragment 2 ::", 
      "Fragment 3 ::", 
      "Fragment 4 ::", 
      "Fragment 5 ::", 
      "and so on....", 
    }; 
    final ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, 
      android.R.layout.simple_list_item_1, android.R.id.text1, values){ 

    }; 

    listView.setAdapter(adapter); 
    //linking from 1 item to other activity stars with if options// 
    listView.setOnItemClickListener(new AdapterView.OnItemClickListener() { 
     public void onItemClick(AdapterView<?> parent, View view, 
           int position, long id) { 

      // global string to class 
      String selectedValue = String.valueOf(parent.getItemAtPosition(position)); 

      switch (selectedValue) { 

       case "Fragment 1 ::": { 
        Intent myIntent = new Intent(view.getContext(), ScrollableTabsActivity.class); 
        startActivityForResult(myIntent, 0); 
        break; 
       } 
       case "Fragment 2 ::": { 
        Intent myIntent = new Intent(view.getContext(), ScrollableTabsActivity.class); 
        startActivityForResult(myIntent, 0); 
        break; 
       } 
       case "Fragment 3 ::": { 
        Intent myIntent = new Intent(view.getContext(), ScrollableTabsActivity.class); 
        startActivityForResult(myIntent, 0); 
        break; 
       } 
       case "Fragment 4 ::": { 
        Intent myIntent = new Intent(view.getContext(), ScrollableTabsActivity.class); 
        startActivityForResult(myIntent, 0); 
        break; 
       } 
       case "Fragment 5 ::": { 
        Intent myIntent = new Intent(view.getContext(), ScrollableTabsActivity.class); 
        startActivityForResult(myIntent, 0); 
        break; 
       } 

      } 


     } 
    }); 
} 

@Override 
public void onClick(View view) { 
    switch (view.getId()) { 
     case R.id.scrollingTabs: 
      startActivity(new Intent(MainActivity.this, ScrollableTabsActivity.class)); 
      break; 

    } 
} 
}

我想你想在ScrollableTabsActivity类打开使用视图寻呼机特异性片段。首先，需要传递参考（which_fragment）装置，其片段需要移动，以便

case "Fragment 1 ::": { 
       Intent myIntent = new 
       Intent(view.getContext(), ScrollableTabsActivity.class); 
       myIntent.putExtra("which_fragment", 0);//0 is reference for //move framgnet 1 
       startActivityForResult(myIntent, 0); 
       break; 
     } 

case "Fragment 2 ::": { 
       Intent myIntent = new 
       Intent(view.getContext(), ScrollableTabsActivity.class); 
       myIntent.putExtra("which_fragment", 1);//1 is reference for //move framgnet 2 
       startActivityForResult(myIntent, 0); 
       break; 
     }

ANS等等...

在ScrollableTabsActivity第一设置视图寻呼机适配器和一个在viewpager方法是setCurrentItem

viewpager.setCurrentItem("which_fragment);

需要调用此方法具设置适配器一样，

viewpager.setCurrentItem(getIntent().getExtra().getInt("which_fragment"));

您的解决方案是不工作也请看看我的scrollingTab的java文件下 – war777

是的，我看到你的代码，但你必须查看传呼机没有编写的代码，设置视图寻呼机适配器后，写这个移动片段你想要什么viewpager.setCurrentItem（“which_fragment）; –

传中startActivity意图数据，您将在SecondActivity检查并打开特定片段

Intent intent = new Intent(MainActivity.this, ScrollableTabsActivity.class); 
intent.putExtra("your_specific_key", key); 
startActivity(intent);

而且在你新的活动，你得到后d通过键和开放的分段数据通过它

String s = getIntent().getStringExtra("your_specific_key");
