我有一个ViewPager显示一些布局。我需要添加两个按钮,并以编程方式在所有布局中显示相同的按钮。查看器是一个带有ViewPager的简单XML。我怎么能这样做?
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// View layout = (View) findViewById(R.id.pager);
//reply.setLayoutParams(new LayoutParams());
// Inicialización
ArrayList<Integer> inte = new ArrayList<Integer>();
viewPager = (ViewPager) findViewById(R.id.pager);
//ArrayList<Integer> pageNumber = new ArrayList<Integer>();
actionBar = getActionBar();
for(int i = 0; i < 39; i++) {
inte.add(i%3);
}
mAdapter = new TabsPagerAdapter(getSupportFragmentManager(), inte);
viewPager.setAdapter(mAdapter);
actionBar.setHomeButtonEnabled(false);
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
// Agrega tabs
for(Integer i =0; i<10; i++){
JSONObject aaa = new JSONObject();
try {
aaa.put("name", "Página "+(i+1));
aaa.put("type", i%3);
System.out.println("name" + " Página ");
inte.add(i%3);
} catch (JSONException e) {
e.printStackTrace();
}
actionBar.addTab(actionBar.newTab().setText("Página "+(i+1)).setTabListener(this));
}

为什么不在XML中定义它们,以便它们出现在ViewPager下面的所有片段中?例如:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/palette_bg"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="?android:attr/actionBarSize"
android:orientation="vertical" >
<com.yourdomain.yourapp.YourCustomViewPager
android:id="@+id/pager"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="10">
</com.yourdomain.yourapp.YourCustomViewPager>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="2dp"
android:layout_marginLeft="2dp"
android:layout_marginRight="2dp"
android:layout_marginTop="2dp"
android:orientation="horizontal" >
//Your buttons here.
</LinearLayout>
