安卓碎片重叠的问题 [英] Android: fragments overlapping issue

问题描述

我面临着重叠的碎片的问题，当我片段选项卡之间切换，并连接到一个标签视图 下面是我的code，请帮忙

 公共类FragmentManage扩展片段实现ActionBar.TabListener {

    私人片段mFragment;

    @覆盖
    公共查看onCreateView（LayoutInflater充气，容器的ViewGroup，
            捆绑savedInstanceState）{

        视图V = inflater.inflate（R.layout.fragment_manage，集装箱，假）;

        OnClickListener clickListener =新OnClickListener（）{
            公共无效的onClick（视图v）{
                FragmentTransaction英尺= getFragmentManager（）的BeginTransaction（）。
                开关（v.getId（））{
                    案例R.id.imageBtnCategory：
                        如果（mFragment == NULL）{
                            mFragment =新FragmentCategory（）;
                        }
                        ft.replace（android.R.id.content，mFragment）;
                        打破;
                    案例R.id.imageBtnManageKey：
                        如果（mFragment == NULL）{
                            mFragment =新FragmentKeys（）;
                        }
                        ft.replace（android.R.id.content，mFragment）;
                        打破;
                    案例R.id.imageBtnChangePswd：
                        如果（mFragment == NULL）{
                            mFragment =新FragmentChangePwd（）;
                        }
                        ft.replace（android.R.id.content，mFragment）;
                        打破;
                }
                ft.commit（）;
             }
        };

        的ImageButton imageBtnCategory =（的ImageButton）v.findViewById（R.id.imageBtnCategory）;
        的ImageButton imageBtnManageKey =（的ImageButton）v.findViewById（R.id.imageBtnManageKey）;
        的ImageButton imageBtnChangePswd =（的ImageButton）v.findViewById（R.id.imageBtnChangePswd）;

        imageBtnCategory.setOnClickListener（clickListener）;
        imageBtnManageKey.setOnClickListener（clickListener）;
        imageBtnChangePswd.setOnClickListener（clickListener）;

        返回伏;
    }

    公共无效onTabSelected（TAB键，FragmentTransaction英尺）{
        mFragment =新FragmentManage（）;
        ft.add（android.R.id.content，mFragment）;
        ft.attach（mFragment）;
    }

    公共无效onTabUnselected（TAB键，FragmentTransaction英尺）{
        ft.remove（mFragment）;
    }

    公共无效onTabReselected（TAB键，FragmentTransaction英尺）{

    }
}
 

解决方案

只是设置背景颜色与＆LT;片段/＆GT; XML文件中。

解决这个问题。

I am facing a problem of overlapping fragments when i switch between tabs and attach fragments to a tab view below is my code please help

public class FragmentManage extends Fragment implements ActionBar.TabListener {

    private Fragment mFragment;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, 
            Bundle savedInstanceState) {

        View v = inflater.inflate(R.layout.fragment_manage, container, false);

        OnClickListener clickListener = new OnClickListener() { 
            public void onClick(View v) {
                FragmentTransaction ft = getFragmentManager().beginTransaction();
                switch(v.getId()) {
                    case R.id.imageBtnCategory:
                        if (mFragment == null){
                            mFragment = new FragmentCategory();
                        }
                        ft.replace(android.R.id.content, mFragment);
                        break;
                    case R.id.imageBtnManageKey:
                        if (mFragment == null){
                            mFragment = new FragmentKeys();
                        }
                        ft.replace(android.R.id.content, mFragment);
                        break;
                    case R.id.imageBtnChangePswd:
                        if (mFragment == null){
                            mFragment = new FragmentChangePwd();
                        }
                        ft.replace(android.R.id.content, mFragment);
                        break;
                }
                ft.commit();
             }
        };

        ImageButton imageBtnCategory = (ImageButton) v.findViewById(R.id.imageBtnCategory);
        ImageButton imageBtnManageKey = (ImageButton) v.findViewById(R.id.imageBtnManageKey);
        ImageButton imageBtnChangePswd = (ImageButton) v.findViewById(R.id.imageBtnChangePswd);

        imageBtnCategory.setOnClickListener(clickListener);
        imageBtnManageKey.setOnClickListener(clickListener);
        imageBtnChangePswd.setOnClickListener(clickListener);

        return v;
    }

    public void onTabSelected(Tab tab, FragmentTransaction ft) {
        mFragment = new FragmentManage();
        ft.add(android.R.id.content, mFragment);
        ft.attach(mFragment);
    }

    public void onTabUnselected(Tab tab, FragmentTransaction ft) {
        ft.remove(mFragment);
    }

    public void onTabReselected(Tab tab, FragmentTransaction ft) {

    }
}

解决方案

Just set a background color to your <fragment /> in XML file.
