Android 加载进度条加载成功数据为空加载失败无网络等状态不同界面的切换

时间：2020-04-22 10:00:10

咱们在开发过程中经常需要从网络上获取数据。这个时候为了增强用户体验。就可能有如下需求：在获取的数据的中时候显示加载中的UI（获取数据需要一定的时间）、如果获取数据失败显示失败的UI、获取的数据为空的时候显示空数据的UI、数据成功获取到的时候才显示获取到的数据列表。总之一句话就是根据不同的状态现实不同的UI。这也是我们这篇文章的重点．接下来咱么就对这一需求做一个简单的封装。

方式1：封装到BaseActivity/BaseFragment中

一般来说，项目中都会有多个Activity或者Fragment,每个界面都会有一些相同的地方，比如标题栏、无数据界面、网络错误界面，每个界面都写就会显得很重复，也不便于维护。所以这个时候就有必要写一个基类来进行封装，也就是BaseActivity或者BaseFragment.

无数据和网络错误的情况。对于上边的标题栏，可能有多种情况，有标题栏，无标题栏，是否有返回按钮，右边是否显示文字或图片。这些情况我们都可以写在基类中。这些公用的界面都是写在BaseActivity的对应的xml文件中。

view_base_state_layout.xml

<?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="/apk/res/android"android:id="@+id/rootView"android:layout_width="match_parent"android:layout_height="match_parent"android:orientation="vertical"><TextViewandroid:id="@+id/title_bar"android:layout_width="match_parent"android:layout_height="44dp"android:gravity="center"android:background="@color/white"android:text="标题"android:textColor="#000000"android:textSize="18sp"android:textStyle="bold" /><LinearLayoutandroid:id="@+id/view_progress"android:layout_width="match_parent"android:layout_height="match_parent"android:layout_below="@id/title_bar"android:layout_gravity="center"android:gravity="center"android:orientation="vertical"><ProgressBarandroid:id="@+id/progress"android:layout_width="wrap_content"android:layout_height="wrap_content" /><TextViewandroid:id="@+id/text_loading"android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_marginTop="10dp"android:text="加载中..." /></LinearLayout><FrameLayoutandroid:id="@+id/view_content"android:layout_width="match_parent"android:layout_height="match_parent"android:layout_below="@id/title_bar"></FrameLayout><LinearLayoutandroid:id="@+id/view_empty"android:layout_width="match_parent"android:layout_height="match_parent"android:layout_below="@id/title_bar"android:gravity="center"><TextViewandroid:id="@+id/text_tip"android:layout_width="wrap_content"android:layout_height="wrap_content"android:text="暂无数据" /></LinearLayout></RelativeLayout>

BaseActivity

/*** Cerated by xiaoyehai* Create date : /11/11 12:14* description :加载进度条，请求成功，请求数据为空，请求失败，无网络等状态不同界面的切换*/public abstract class BaseActivity extends AppCompatActivity {private RelativeLayout mRootView;private View mViewProgress;private FrameLayout mViewContent;private View mViewEmpty;private TextView mTextTip;private TextView mTvTitleBar;@Overrideprotected void onCreate(@Nullable Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.view_base_state_layout);findViews();init();}public void initTitleBar(boolean isShow, String title) {mTvTitleBar.setText(title);if(isShow) {mTvTitleBar.setVisibility(View.VISIBLE);}else {mTvTitleBar.setVisibility(View.GONE);}}public void showProgressView() {showView(R.id.view_progress);}public void showContentView() {showView(R.id.view_content);}public void showEmptyView() {showView(R.id.view_empty);}public void showEmptyView(int resId) {showEmptyView();mTextTip.setText(resId);}/*** 请求数据为空，请求失败，无网络等状态都用同一个布局** @param msg*/public void showEmptyView(String msg) {showEmptyView();mTextTip.setText(msg);}public void showView(int viewId) {for (int i = 1; i < mRootView.getChildCount(); i++) {if (mRootView.getChildAt(i).getId() == viewId) {mRootView.getChildAt(i).setVisibility(View.VISIBLE);} else {mRootView.getChildAt(i).setVisibility(View.GONE);}}}private void findViews() {mRootView = findViewById(R.id.rootView);mTvTitleBar = findViewById(R.id.title_bar);mViewProgress = findViewById(R.id.view_progress);mViewContent = (FrameLayout) findViewById(R.id.view_content);mViewEmpty = findViewById(R.id.view_empty);mTextTip = (TextView) findViewById(R.id.text_tip);mViewEmpty.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View v) {onReload();}});//将当前界面的布局添加到BaseActivity中去View realContentView = LayoutInflater.from(this).inflate(getLayoutId(), mViewContent, true);}public void onReload() {}protected abstract int getLayoutId();protected abstract void init();}

使用

public class SecondActivity extends BaseActivity {@Overrideprotected int getLayoutId() {return R.layout.activity_second;}@Overrideprotected void init() {initTitleBar(true, "SecondActivity");loadData();}//模拟加载数据private void loadData() {showProgressView();new Handler().postDelayed(new Runnable() {@Overridepublic void run() {int code = 202;switch (code) {case 200:showContentView();break;case 201:showEmptyView("暂无数据");break;case 202:showEmptyView("加载失败");break;case 203:showEmptyView("无网络");break;}}}, 2000);}@Overridepublic void onReload() {super.onReload();loadData();}}

BaseFragment

public abstract class BaseFragment extends Fragment implements View.OnClickListener {protected Context mContext;private View mViews;private FrameLayout mRootView;private View mViewProgress;private FrameLayout mViewContent;private View mViewEmpty;private TextView mTextTip;private TextView mTvTitleBar;@Overridepublic void onCreate(@Nullable Bundle savedInstanceState) {super.onCreate(savedInstanceState);mContext = getActivity();}@Nullable@Overridepublic View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {mViews = inflater.inflate(R.layout.view_base_state_layout, container, false);findViews();return mViews;}@Overridepublic void onActivityCreated(@Nullable Bundle savedInstanceState) {super.onActivityCreated(savedInstanceState);setRealContentView();init();}public void initTitleBar(boolean isShow, String title) {mTvTitleBar.setText(title);if (isShow) {mTvTitleBar.setVisibility(View.VISIBLE);} else {mTvTitleBar.setVisibility(View.GONE);}}private void findViews() {mRootView = mViews.findViewById(R.id.rootView);mTvTitleBar = mViews.findViewById(R.id.title_bar);mViewProgress = mViews.findViewById(R.id.view_progress);mViewContent = (FrameLayout) mViews.findViewById(R.id.view_content);mViewEmpty = mViews.findViewById(R.id.view_empty);mTextTip = (TextView) mViews.findViewById(R.id.text_tip);mViewEmpty.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View v) {onReload();}});}protected void onReload() {}private void setRealContentView() {View realContentView = LayoutInflater.from(getActivity()).inflate(getLayoutId(), mViewContent, true);}public void showProgressView() {showView(R.id.view_progress);}public void showContentView() {showView(R.id.view_content);}public void showEmptyView() {showView(R.id.view_empty);}public void showEmptyView(int resId) {showEmptyView();mTextTip.setText(resId);}public void showEmptyView(String msg) {showEmptyView();mTextTip.setText(msg);}public void showView(int viewId) {for (int i = 1; i < mRootView.getChildCount(); i++) {if (mRootView.getChildAt(i).getId() == viewId) {mRootView.getChildAt(i).setVisibility(View.VISIBLE);} else {mRootView.getChildAt(i).setVisibility(View.GONE);}}}protected abstract int getLayoutId();protected abstract void init();}

方式2：自定义一个控件来切换布局

使用

public class ThirdActivity extends BaseActivity2 {private TextView mTvContent;private FrameLayout mFlContainer;@Overrideprotected int getLayoutId() {return R.layout.activity_third;}@Overrideprotected void init() {//mFlContainer = findViewById(R.id.fl_container);mTvContent = findViewById(R.id.tv_content);}@Overrideprotected ViewStatusLayout.Builder createViewStatusBuilder() {return super.createViewStatusBuilder()//.setContainer(mFlContainer) //设置父容器//.setUseStatusView(false) //是否使用状态图，有些页面不需要展示无数据页，无网络页.setNoDataTip("暂时没有数据哦").setRetryTip("重新加载").setRetryClickListener(new ViewStatusLayout.IRetryClickListener() {@Overridepublic void click(int viewStatus) {loadData();}});}@Overrideprotected void initData() {loadData();}//模拟加载数据private void loadData() {mViewStatusLayout.switchView(ViewStatus.LOADING_START);new Handler().postDelayed(new Runnable() {@Overridepublic void run() {int code = 202;switch (code) {case 200:mViewStatusLayout.switchView(ViewStatus.HASDATA);mTvContent.setText("content");break;case 201:mViewStatusLayout.switchView(ViewStatus.NODATA);break;case 202:mViewStatusLayout.switchView(ViewStatus.NONETWORK);break;case 203:mViewStatusLayout.switchView(ViewStatus.EMPTY);break;}}}, 2000);}}

还可以在activity_third.xml加上FrameLayout，id写死为view_status_container，其他都不变

如果FrameLayout的id不是view_status_container，要在代码中设置父容器：

<FrameLayoutandroid:layout_below="@id/ctb_title"android:id="@+id/fl_container"android:layout_width="match_parent"android:layout_height="match_parent"/>

@Overrideprotected void init() {mFlContainer = findViewById(R.id.fl_container);}@Overrideprotected ViewStatusLayout.Builder createViewStatusBuilder() {return super.createViewStatusBuilder().setContainer(mFlContainer) //设置父容器//.setUseStatusView(false) //是否使用状态图，有些页面不需要展示无数据页，无网络页.setNoDataTip("暂时没有数据哦").setRetryTip("重新加载").setRetryClickListener(new ViewStatusLayout.IRetryClickListener() {@Overridepublic void click(int viewStatus) {loadData();}});}
