问题描述

我正在放大一个对话框中的布局，该对话框包含一个滚动视图，但是该布局没有滚动。我已经从stackoverflow提到了很多问题，但是后来也无法正常工作。我的layout.xml文件如下：

 <？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

< ImageView 
 android：layout_width = wrap_content 
 android：layout_height = 300dp 
 android：layout_margin = 3dp 
 android： layout_weight = 0.02 
 android：src = @ drawable / updateimg2 /> 
 
<按钮
 android：id = @ + id / btn_upgrade 
 android：layout_width = fill_parent 
 android：layout_height = wrap_content

 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>

解决方案< ScrollView中的/ div>

android：fillViewport = true解决了我的问题。现在，它甚至可以在对话框中滚动。

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_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();
      }

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