我正在为 ViewPager https://github.com/astuetz/PagerSlidingTabStrip使用 PagerSlidingTabStrip 库。
当我按下按钮到特定片段时，我想更改片段。
MainActivity.java：
package com.astuetz.viewpager.extensions.sample;
@TargetApi(Build.VERSION_CODES.HONEYCOMB)
public class MainActivity extends FragmentActivity {
private PagerSlidingTabStrip tabs;
private ViewPager pager;
private MyPagerAdapter adapter;
private int currentColor = 0xFF96AA39;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
tabs = (PagerSlidingTabStrip) findViewById(R.id.tabs);
pager = (ViewPager) findViewById(R.id.pager);
adapter = new MyPagerAdapter(getSupportFragmentManager());
pager.setAdapter(adapter);
final int pageMargin = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 4, getResources()
.getDisplayMetrics());
pager.setPageMargin(pageMargin);
tabs.setViewPager(pager);
tabs.setIndicatorColor(currentColor);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.action_contact:
QuickContactFragment dialog = new QuickContactFragment();
dialog.show(getSupportFragmentManager(), "QuickContactFragment");
return true;
}
return super.onOptionsItemSelected(item);
}
public class MyPagerAdapter extends FragmentPagerAdapter {
private final String[] TITLES = { "Categories", "Home", "Top Paid", "Top Free", "Top Grossing", "Top New Paid",
"Top New Free", "Trending" };
public MyPagerAdapter(FragmentManager fm) {
super(fm);
}
@Override
public CharSequence getPageTitle(int position) {
return TITLES[position];
}
@Override
public int getCount() {
return TITLES.length;
}
@Override
public Fragment getItem(int position) {
return SuperAwesomeCardFragment.newInstance(position);
}
}
}
片段.java：
public class SuperAwesomeCardFragment extends Fragment {
private static final String ARG_POSITION = "position";
private int position;
public static SuperAwesomeCardFragment newInstance(int position) {
SuperAwesomeCardFragment f = new SuperAwesomeCardFragment();
Bundle b = new Bundle();
b.putInt(ARG_POSITION, position);
f.setArguments(b);
return f;
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
position = getArguments().getInt(ARG_POSITION);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
LayoutParams params = new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT);
FrameLayout fl = new FrameLayout(getActivity());
fl.setLayoutParams(params);
final int margin = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 8, getResources()
.getDisplayMetrics());
TextView v = new TextView(getActivity());
params.setMargins(margin, margin, margin, margin);
v.setLayoutParams(params);
v.setLayoutParams(params);
v.setGravity(Gravity.CENTER);
v.setBackgroundResource(R.drawable.background_card);
if(position==0){
v.setText("dddd");
Button bb=new Button(getActivity());
bb.setText("goo");
**bb.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
}**
});
}else
v.setText("CARD " + (position + 1));
fl.addView(v);
return fl;
}
}
