Issue when using Scrollview inside Dialog

问题

I am inflating a layout inside a dialog, which consist of a scrollview but the layout is not scrolling. I have referred so many questions from stackoverflow but then also its not working. My layout.xml is given below:

<?xml version="1.0" encoding="utf-8"?>
  <ScrollView 
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="fill_parent"
         android:layout_height="match_parent"
        android:layout_margin="5dp"
        android:background="@color/White"
       >

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@color/White"
        android:scrollbars="vertical"
            android:scrollbarAlwaysDrawVerticalTrack="true"
        android:orientation="vertical" >

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center_horizontal"
            android:layout_margin="5dp"
            android:text="Update available"
            android:textColor="#000000" />

        <TextView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_margin="5dp"
            android:gravity="center"
            android:text="@string/upgrade_msg"
            android:textColor="#000000" />

        <ImageView
            android:layout_width="wrap_content"
            android:layout_height="300dp"
            android:layout_margin="3dp"
            android:layout_weight="0.02"
            android:src="@drawable/updateimg2" />

        <Button
            android:id="@+id/btn_upgrade"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_below="@id/tv_forget_pwd"
            android:layout_marginLeft="10dp"
            android:layout_marginRight="10dp"
            android:layout_marginTop="10dp"
            android:background="@color/White"
            android:gravity="center"
            android:text="Upgrade Now"
            android:textColor="@color/Black" />

        <ImageView
            android:id="@+id/imageView1"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_marginLeft="10dp"
            android:layout_marginRight="10dp"
            android:layout_marginTop="10dp"
            android:scaleType="fitXY"
            android:src="@drawable/line_y_h" />

        <Button
            android:id="@+id/btn_remind"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_below="@id/tv_forget_pwd"
            android:layout_marginLeft="10dp"
            android:layout_marginRight="10dp"
            android:layout_marginTop="10dp"
            android:background="@color/White"
            android:gravity="center"
            android:text="Remind Me Later"
            android:textColor="@color/Blue" />

        <ImageView
            android:id="@+id/imageView2"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginLeft="10dp"
            android:layout_marginRight="10dp"
            android:layout_marginTop="10dp"
            android:scaleType="fitXY"
            android:src="@drawable/line_y_h" />
    </LinearLayout>

</ScrollView>

Dialog code

  public void show_Alert_version_custom(String str, final String url,
            final String exitStatus)// use for
    {
        final Dialog dialog = new Dialog(Splash.this);
        dialog.setContentView(R.layout.version_update);
        dialog.setTitle(getString(R.string.alert_title));
        Button dialogButton2 = (Button) dialog.findViewById(R.id.btn_remind);
        dialogButton = (Button) dialog.findViewById(R.id.btn_upgrade);
        ImageView viewLine = (ImageView) dialog.findViewById(R.id.imageView2);


        // if button is clicked, close the custom dialog
        dialogButton.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {}
        });

        // if button is clicked, close the custom dialog
        dialogButton2.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {}
        });

        dialog.show();
    }

回答1:

android:fillViewport="true" in ScrollView solved my problem. Now its scrolling even inside dialog.

回答2:

You can use simply below code on ScollView. it's working fine.

<ScrollView>
    <LinearLayout android:orientation="vertical"
            android:scrollbars="vertical"
            android:scrollbarAlwaysDrawVerticalTrack="true">

    </LinearLayout>
</ScrollView>
