我的 ViewPager 中的一个布局有一个按钮。“R.layout.add_site”。我想要点击按钮的选项,它会滚动到我的特定页面。我已经可以选择滑动到特定页面,但我希望两者都有。
现在我确定有办法做到这一点,但由于某种原因,我无法弄清楚。
您会看到我已经尝试过,但只是不知道调用什么方法才能使其滚动到所需的页面。这是 R.layout.main。
这是我的代码。
public class fieldsActivity extends Activity {
Button addSiteButton;
Button cancelButton;
Button signInButton;
/**
* Called when the activity is first created.
*/
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// to create a custom title bar for activity window
requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);
setContentView(R.layout.fields);
// use custom layout title bar
getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.topbar);
Pager adapter = new Pager();
ViewPager mPager = (ViewPager) findViewById(R.id.fieldspager);
mPager.setAdapter(adapter);
mPager.setCurrentItem(1);
addSiteButton = (Button) findViewById(R.id.addSiteButton);
addSiteButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// Don't know what method to call!?
}
});
cancelButton = (Button) findViewById(R.id.cancel_button);
signInButton = (Button) findViewById(R.id.sign_in_button);
}
private class Pager extends PagerAdapter {
public int getCount() {
return 3;
}
@Override
public Object instantiateItem(View collection, int position) {
LayoutInflater inflater = (LayoutInflater) collection.getContext()
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
int resId = 0;
switch (position) {
case 0:
resId = R.layout.field01;
break;
case 1:
resId = R.layout.add_site;
break;
case 2:
resId = R.layout.main;
break;
}
View view = inflater.inflate(resId, null);
((ViewPager) collection).addView(view, 0);
return view;
}
@Override
public void destroyItem(View arg0, int arg1, Object arg2) {
((ViewPager) arg0).removeView((View) arg2);
}
@Override
public boolean isViewFromObject(View arg0, Object arg1) {
return arg0 == ((View) arg1);
}
@Override
public Parcelable saveState() {
return null;
}
}
}
