本文主要是介绍ViewPager+DialogFragment实现弹窗左右滑动切换，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
开发中可能需要作出需要弹出浮层给用户展示一些信息，并且需要浮层能够左右滑动切换的功能。
这就需要用到ViewPager+DialogFragment来实现了，可以随意添加fragment，并且能够左右滑动，随时关闭，也可以定位到打开时在想要有限展示的fragment。
下边是截图和代码：
主界面MainActivity:
public class MainActivity extends FragmentActivity implements OnClickListener{@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);Button abrir = (Button) findViewById(R.id.botao);Button abrir2 = (Button) findViewById(R.id.botao2);abrir.setOnClickListener(this);abrir2.setOnClickListener(this);}@Overridepublic void onClick(View v) {DialogFragmentWindow fragmentWindow = new DialogFragmentWindow();Bundle args = new Bundle();args.putString("first", "这是第一个浮层");args.putString("second", "这是第二个浮层");switch (v.getId()) {case R.id.botao:args.putString("from", "one");fragmentWindow.setArguments(args);fragmentWindow.show(getSupportFragmentManager(), "");break;case R.id.botao2:args.putString("from", "two");fragmentWindow.setArguments(args);fragmentWindow.show(getSupportFragmentManager(), "");break;}}}DialogFragmentWindow 继承自DialogFragment用来装载fragment
public class DialogFragmentWindow extends DialogFragment {public static DialogFragmentWindow intance;private String first = "";private String second = "";private String from = "";@Overridepublic View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {View view = inflater.inflate(R.layout.window, container);intance = this;first = getArguments().getString("first");second = getArguments().getString("second");from = getArguments().getString("from");ViewPager viewPager = (ViewPager) view.findViewById(R.id.viewPager);List<Fragment> fragments = getFragments();AcoesMuscularesAdapter ama = new AcoesMuscularesAdapter(getChildFragmentManager(), fragments);viewPager.setAdapter(ama);if ("two".equals(from)) {//定位在第二个fragmentviewPager.setCurrentItem(1);}getDialog().getWindow().requestFeature(Window.FEATURE_NO_TITLE);return view;}//全屏显示
// @Override
// public void onStart() {
// super.onStart();
// Dialog dialog = getDialog();
// if (dialog != null) {
// int width = ViewGroup.LayoutParams.MATCH_PARENT;
// int height = ViewGroup.LayoutParams.MATCH_PARENT;
// dialog.getWindow().setLayout(width, height);
// }
// }private List<Fragment> getFragments() {//添加多个fragmentList<Fragment> fList = new ArrayList<Fragment>();fList.add(MyPagerFragment.newInstance(this, first, 1));fList.add(MyPagerFragment.newInstance(this, second, 2));return fList;}class AcoesMuscularesAdapter extends FragmentPagerAdapter{private List<Fragment> fragments;public AcoesMuscularesAdapter(FragmentManager fm, List<Fragment> fragments){super(fm);this.fragments = fragments;}@Overridepublic Fragment getItem(int position) {return this.fragments.get(position);}@Overridepublic int getCount() {return this.fragments.size();}}
}
接收并展示数据的fragment
public class MyPagerFragment extends Fragment {public static final String EXTRA_MESSAGE = "EXTRA_MESSAGE";public static final MyPagerFragment newInstance(DialogFragment dialogFragment, String message,int item) {MyPagerFragment f = new MyPagerFragment();Bundle bdl = new Bundle(item);f.item = item;f.dialogFragment = dialogFragment;bdl.putString(EXTRA_MESSAGE, message);f.setArguments(bdl);return f;}private int item;private TextView mTvMsg;private Button mBtnCancle;private DialogFragment dialogFragment;@Overridepublic View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {final View view = inflater.inflate(R.layout.pager_fragment, container, false);String msg = getArguments().getString(EXTRA_MESSAGE);mTvMsg = (TextView) view.findViewById(R.id.tv_msg);mTvMsg.setText(msg);mBtnCancle = (Button) view.findViewById(R.id.btn_cancle);mBtnCancle.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View v) {dialogFragment.dismiss();}});return view;}}
