StateView 一个轻量级状态显示控件

StateView

StateView一个轻量级的控件, 继承自 View , 吸收了 ViewStub 的一些特性, 初始状态下是不可见的, 不占布局位置, 占用内存少。当进行操作显示空/重试/加载视图后, 该视图才会被添加到布局中。所以当用不到显示视图的时候, 占用内存是很少的。由于目前只有3个视图, 所以至多只会添加3次, 相对于其他具有同样功能的一些控件, StateView更具有优势。

Usage

compile 'com.github.nukc.stateview:library:0.3.2'

添加到布局:

<com.github.nukc.stateview.StateView
        android:id="@+id/stateView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>

显示空视图: mStateView.showEmpty();
显示加载视图: mStateView.showLoading();
显示重试视图: mStateView.showRetry();
显示内容: mStateView.showContent(); //实质就是setVisibility(GONE);
设置重试点击事件:

mStateView.setOnRetryClickListener(new StateView.OnRetryClickListener() {
        @Override
        public void onRetryClick() {
            //do something, no need to call showLoading()
            //不需要调用showLoading()方法, StateView自会调用
        }
    });

或直接在代码中使用:

注入到Activity

mStateView = StateView.inject(Activity activity);
    //如果有actionbar/toolbar
    mStateView = StateView.inject(activity, true);

注入到ViewGroup

mStateView = StateView.inject(ViewGroup parent);

    mStateView = StateView.inject(ViewGroup parent, boolean hasActionBar);

//可用于在Fragment的onCreateView中
    mStateView = StateView.inject(View view);

    mStateView = StateView.inject(View view, boolean hasActionBar);

ChangeLog

Version 0.3.2

进一步测试, 增加Sample; 删除没必要的方法, 考虑到注入不应该遮挡工具栏, 为此增加inject方法

Version 0.3.1

增加静态方法: inject(View view),该参数view必须是viewGroup,可用于在Fragment中

Version 0.3.0

增加静态方法: inject(Activity activity),用于把StateView添加到DecorView中;

inject(ViewGroup parent),用于添加到ViewGroup中

Version: 0.2.4

修复显示LoadingView后还能触摸下层的View

Version: 0.2.3

修复issues #2

Version: 0.2.1

更新gradle和library版本, 增加一个私有方法showView。

Version: 0.2.0

修复v0.1.0版本中当使用layout_below的时候addView可能无法正常显示的问题。

Version: 0.1.0

测试Sample得知：

<com.github.nukc.stateview.StateView
             android:id="@+id/stateView"
             android:layout_width="match_parent"
             android:layout_height="match_parent"
             android:layout_marginTop="100dp"
             tools:visibility="gone" />

使用 android:layout_below="@+id/ll" 的话 , addView有时会无法正常显示，有时却正常。在寻找问题。。

3个按钮错乱多按几次，有几率会出现不显示的情况。
