        <StatusBar />
        <MessageToast ref='toast'/>
        <View style={styles.contentView}>
            
             <TitleButton title='获取成功' style={{width:100,height:40}} onPress={()=>this.onPress('Success')} />
             <TitleButton title='获取失败' style={{width:100,height:40}} onPress={()=>this.onPress('Fail')} />
             <TitleButton title='显示toast' style={{width:100,height:40}} onPress={()=>this.onPress('Toast')} />
             <TitleButton title='显示加载中' style={{width:100,height:40}} onPress={()=>this.onPress('Loading')} />
         </View>
      </View>
      );
  }


onPress(event){

    if(event=='Success'){
      this.refs.toast.showSuccess('获取接口成功');
    }
    else if(event=='Fail'){
      this.refs.toast.showFail('获取接口失败');
    }
    else if(event=='Toast'){
      this.refs.toast.showMessage('哇哈哈哈哈哈哈哈哈哈哈哈哈哈哈哇哈哈哈哈哈哈哈哈哈哈哈哈哈哈');
    }
    else if(event=='Loading'){
      this.refs.toast.showLoading('加载中...',2000);
    }
  }
