reactjs- React 本机模态定位

(reactjs - React Native Modal Positioning)

发布于 2020-11-27 18:25:48

我使用的是React Native内置的Modal（特别是我使用的是React Native Paper变体）。默认情况下，这似乎在屏幕中间打开。但是，如果你要在Modal中进行一些文本输入，则在屏幕顶部打开或知道键盘的情况下，它会更加有用。但是，我找不到使它正常工作的方法。

我的（简化的）模态代码是：

     <Portal>
      <Modal visible={visibleModalNew} onDismiss={closeModalNew} contentContainerStyle={styles.modalContainer} >
        <View>
          <Title>New</Title>
          <View>
            <TextInput
              mode="outlined"
              label="Data"
              style={{alignSelf:'center', width:'95%'}}
              defaultValue={newData}
              onChangeText={newData=> setNewData(newData)}
              onSubmitEditing={() => handleDone()}
            />
            <Button onPress={() => doSomething()}>Do something</Button>
          </View>
        </View>
      </Modal>
    </Portal>

啊，想通了。我将模态包装在KeyboardAwareView中，从模态中删除了可见的道具，然后将其全部包装在条件渲染中，然后将可见的道具放在那里。似乎按预期工作。
