TouchableOpacity

Question

'a dokunmadan yürüdüğümde, kullanıcı dokunulduğunda defferent işlevlerini yürütmek istediğim üç TouchableOpacities var.ama ancak, uygulamayı başlattıktan sonra, dokunmadan çalışabilen opakitelerdeki işlevler, sonsuza dek çalıştırılıyor.İşte bunu çözebilirim.

TouchableOpacities

<View style={styles.headerButtonMain}> 
        <View style={styles.headerButton}> 
          <TouchableOpacity style={{ 
           marginRight: 25 
          }} onPress={this.loadListData()}> 
           <Image style={styles.button} source={require('./img/imgCase.png')}/> 
          </TouchableOpacity> 

          <TouchableOpacity style={{ 
           marginRight: 25 
          }} onPress={this.loadCustomerData()}> 
           <Image style={styles.button} source={require('./img/imgCall.png')}/> 
          </TouchableOpacity> 
          <TouchableOpacity style={{ 
           marginRight: 25 
          }} onPress={this._onPressButton}> 
           <Image style={styles.button} source={require('./img/imgCase.png')}/> 
          </TouchableOpacity> 
        </View> 
        <Text style={{ 
         fontSize: 18, 
         color: '#fff', 
         marginLeft: 15, 
         marginTop: 38, 
         marginBottom: 20 
        }}>My Cases</Text> 
       </View> 

sorun onPress bir işlev bekliyor olmasıdır fonksiyonunu

render() { 
      if(this.viewCaseData === true){ 
      var caseList = <View > 
       <ListView dataSource={this.state.dataSource} renderRow={this.renderRow.bind(this)}></ListView> 

      </View> 
    }else{ 
      var caseList = <ScrollView style={{ 
       marginLeft: 10, 
       marginRight: 10 
      }}> 
       <View style={{

veya

<TouchableOpacity onPress={() => this.loadListData()}> 

birincisi (bu bağlar yapabilir ya
