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;
}

}
