How to make whole activity scrollable according to the data inside it

问题

I have tried LinearLayout inside which I put several textview. I completely use weights for each and every view. Problem arises when data becomes too much in lenght and textview not shows it completely. I also tried tabletlayout but that thing also not works beacuse ultimately tablelayout is inside linear layout having weight,so it doesn't grows beyond a certain limit. I want to know how can I make a activity scrollable with showing all data while using weights.

Use Scrollview in xml Layout of your activity.

Example: XML code for your activity:

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical"
    android:padding="10dp"
    android:fillViewport="false">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical">
        <ImageView
            android:id="@+id/imageView"
            android:layout_width="wrap_content"
            android:layout_height="200dp"
            android:scaleType="centerCrop"
            android:src="@drawable/image" />

        <Button
            android:id="@+id/button"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="KNOW MORE" />

        <TextView
            android:id="@+id/textView"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="@string/title"
            android:textAppearance="?android:attr/textAppearanceLarge" />

        <TextView
            android:id="@+id/textView2"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="@string/description"
            android:textAppearance="?android:attr/textAppearanceSmall" />
    </LinearLayout>
</ScrollView>

You can Use Scroll View With Linear Layout as well as With Relative layout.

You Can try this code, Just Copy and paste in XML File. U'll Get Your ans :)

You can make your activity scrollable using ScrollView. Its very simple and effective to use.Just copy code of ScrollView from below and paste it in your layout xml file. You can use this ScrollView with Linear as well as Relative Layout also. Just need to remember one thing,ScrollView can have only one child widget.If you want more Children then wrap them into one container.

<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:orientation="vertical">

        <LinearLayout
            android:layout_width="fill_parent"
            android:layout_height="wrap_content">

            <ImageView
                android:id="@+id/imageView1"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:src="@drawable/xyz.png"/>

        </LinearLayout>

        <LinearLayout
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:orientation="horizontal">

            <TextView
                android:id="@+id/textView1"
                android:layout_width="0dp"
                android:layout_height="wrap_content"
                android:layout_weight="1"
                android:text="TextView1"/>

        </LinearLayout>

        <LinearLayout
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:orientation="horizontal">

            <TextView
                android:id="@+id/textView2"
                android:layout_width="0dp"
                android:layout_height="wrap_content"
                android:layout_weight="1"
                android:text="TextView2"/>

            <TextView
                android:id="@+id/textView3"
                android:layout_width="0dp"
                android:layout_height="wrap_content"
                android:layout_weight="1"
                android:text="TextView3"/>

            <TextView
                android:id="@+id/textView4"
                android:layout_width="0dp"
                android:layout_height="wrap_content"
                android:layout_weight="1"
                android:text="TextView4"/>

        </LinearLayout>

        <LinearLayout
            android:layout_width="fill_parent"
            android:layout_height="wrap_content">

            <Button
                android:id="@+id/btn_demo"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_gravity="center_horizontal"
                android:text="Demo" />

        </LinearLayout>

    </LinearLayout>

</ScrollView>

Basically you have to put your entire xml layout inside a scroll view. See the other code examples.
