Android 自定义LoddingView效果

在开发当中当我们且切换页面的时候都会有个进度条来告诉我们的用户数据正在加载中，一般会用在faragment和Activity，好啦 直接看代码

public class CommonLoadingView extends FrameLayout {
    //加载时显示文字
    protected TextView mLoadingTextTv;
    public Context mContext;
    //加载错误视图
    protected LinearLayout mLoadErrorLl;
    //加载错误点击事件处理
    private LoadingHandler mLoadingHandler;
    //加载view
    private View loadingView;
    //加载失败view
    private View loadingErrorView;
    //数据为空
    private View emptyView;


    public CommonLoadingView(Context context, AttributeSet attrs) {
        this(context, attrs, 0);
    }

    public CommonLoadingView(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
        mContext = context;
    }

    public void setLoadingHandler(LoadingHandler loadingHandler) {
        mLoadingHandler = loadingHandler;
    }

    public void setLoadingErrorView(View loadingErrorView) {
        this.removeViewAt(1);
        this.loadingErrorView = loadingErrorView;
        this.loadingErrorView.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                if (mLoadingHandler != null) {
                    mLoadingHandler.doRequestData();
                    CommonLoadingView.this.load();
                }
            }
        });
        this.addView(loadingErrorView,1);
    }

    public void setLoadingView(View loadingView) {
        this.removeViewAt(0);
        this.loadingView = loadingView;
        this.addView(loadingView,0);
    }

    @Override
    protected void onFinishInflate() {
        super.onFinishInflate();
        loadingView = inflate(mContext, R.layout.common_loading_view, null);
        loadingErrorView = inflate(mContext, R.layout.network_layout, null);
        emptyView = inflate(mContext, R.layout.empty_layout, null);
        this.addView(loadingView);
        this.addView(loadingErrorView);
        this.addView(emptyView);
        loadingErrorView.setVisibility(GONE);
        emptyView.setVisibility(GONE);
        initView(this);
    }


    public void setMessage(String message) {
        mLoadingTextTv.setText(message);
    }


    private void initView(View rootView) {
        mLoadingTextTv = (TextView) rootView.findViewById(R.id.loading_text_tv);
        mLoadErrorLl = (LinearLayout) rootView.findViewById(R.id.load_error_ll);
        mLoadErrorLl.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                if (mLoadingHandler != null) {
                    CommonLoadingView.this.load();
                    mLoadingHandler.doRequestData();
                }
            }
        });
    }

    public void load(){
        loadingView.setVisibility(VISIBLE);
        loadingErrorView.setVisibility(GONE);
        emptyView.setVisibility(GONE);
    }

    public void load(String message){
        mLoadingTextTv.setText(message);
        loadingView.setVisibility(VISIBLE);
        loadingErrorView.setVisibility(GONE);
        emptyView.setVisibility(GONE);
    }


    public void loadSuccess(){
        this.loadSuccess(false);
    }

    public void loadSuccess(boolean isEmpty){
        loadingView.setVisibility(GONE);
        loadingErrorView.setVisibility(GONE);
        if (isEmpty) {
            emptyView.setVisibility(VISIBLE);
        }else{
            emptyView.setVisibility(GONE);
        }
    }


    public void loadError(){
        loadingView.setVisibility(GONE);
        loadingErrorView.setVisibility(VISIBLE);
    }


    public interface LoadingHandler{
        void doRequestData();
    }
}
我们看一下common_loading_view布局 

我们再看一下corner_dialog里

最后在onCreate()方法里 调用load()方法即可
