ViewPager+DialogFragment实现弹窗左右滑动切换

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{

	@Override
    protected 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);
    }

	@Override
	public 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 = "";
	
    @Override
    public 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fragment
        	viewPager.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fragment
		List<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;
        }

        @Override
		public Fragment getItem(int position) {
			return this.fragments.get(position);
		}

        @Override
        public 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;

	@Override
	public 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() {
			
			@Override
			public void onClick(View v) {
				dialogFragment.dismiss();
			}
		});

		return view;
	}

}
