React Native Keyboard pushing the header(Android)

When the TextInput is onFocus the keyboard keeps pushing the content and the header outside the screen, with or without the KeyboardAvoidingView Component, the behaviour is the same.
I tried the following in the manifest:
android:windowSoftInputMode="adjustPan"
when I changed the above to
android:windowSoftInputMode="adjustResize"
it works fine the header is not being pushed but it pushes all the views which is found under the TextInput above the keyboard which is not desired
android:windowSoftInputMode="adjustNothing"
it shows no effect even if i added the KeyboardAvoidingView Component

TextInput not showing on focus

I have a text input named email or user name when i click on it, it doesn't show the values I type,I think it's because of the screen size, is there anyway I can adjust the Textinput so that when I click on it, the full text input show and I can see my values typed.
The other text inputs underneath it shows, but it doesn't show, should i wrap it in a scrollview, please any help will be nice, Thanks.

This works to me:
Use the Keyboard API from React Native to set listeners on keyboard.
this.keyboardDidShowListener = Keyboard.addListener('keyboardDidShow', this._keyboardDidShow);
this.keyboardDidHideListener = Keyboard.addListener('keyboardDidHide', this._keyboardDidHide);
Use a state variable to set scrollEnabled prop of the ScrollView (that wrap your content) to true or false according to the keyboard is shown or not. So when the keyboard is shown the scroll will be enabled.
At the bottom of your content add a conditional View with some height that is active when the keyboard is shown thus you will be able to scroll.
Remember this:
componentWillUnmount () {
this.keyboardDidShowListener.remove();
this.keyboardDidHideListener.remove();
}

Place your entire code inside ScrollView and use fixed positions for your views. Try it.

There is no onchangetext() event in first and last textInput.try to add it in your code.
constructor(props) {
super(props);
this.state = { email:'',text:'',password:'' };
}
...
<TextInput
onChangeText={(email) => this.setState({email})}
value={this.state.email}
/>
<TextInput
style={{height: 40, borderColor: 'gray', borderWidth: 1}}
onChangeText={(text) => this.setState({text})}
value={this.state.text}
/>
<TextInput
style={{height: 40, borderColor: 'gray', borderWidth: 1}}
onChangeText={(password) => this.setState({password})}
value={this.state.password}
/>
i hope this helps you

We had similar problem for android, This is how we handle it was, may be this will help you to find a better solution.
You need to create a const and assign status bar size as a value.
const NAVBAR_HEIGHT = Platform.select({
ios: { marginTop: 0 },
android: { marginTop: window.height / 8 }
});
Then in the style section should add this line,
marginTop: NAVBAR_HEIGHT.marginTop
Like this,
const styles = StyleSheet.create({
container: {
flex: 1,
backgroundColor: "#E7EBF0",
marginTop: NAVBAR_HEIGHT.marginTop
}
});
This is how we create status bar for our application,
<View style={styles.container}>
{/* if ios status bar will be added to the screen */}
{Platform.OS === "ios" ? (
<Statusbar backgroundColor="#000000" barStyle="light-content" />
) : null}
</View>

After seeing your complete code, I can see you are using the components from NativeBase. If you see the code, it is trying to merge styles and send that to the react native picker.
By looking at the documentation, you are actually setting the styles and I am guessing the native base code is adding another styles which RN does not like.
So, take a look at this documentation, and instead of using the style prop, use the ones provided by the framework:
https://docs.nativebase.io/Components.html#picker-def-headref
See that they have headerStyle, itemStyle, itemTextStyle and textStyle.

Text on Android does not allow nested views. Only nested Texts are allowed (they convert to Spans).

As noted by #ravi-teja, use absolute positioning. Also, your warning arises because styleAttr is not a style attribute (the name is misleading) but a prop. You can also show and hide it programmatically using a boolean (myCondition) (that you can maybe store in your state). You should do something like this:
var ProgressBar = require('ProgressBarAndroid');
// ...
render(){
const {width, heigth} = Dimensions.get('window'); // The dimensions may change due to the device being rotated, so you need to get them in each render.
return (
//...
{this.state.myCondition && <ProgressBar styleAttr={'LargeInverse'} style={{position: 'absolute', left: width/2, height: height/2, justifyContent:'center',alignItems:'center', color:'white'}} />}
//...
}
In addition to that and as others said, you should give a try to ActivityIndicator, since it works for both iOS and Android.
