CheckBox bleibt nicht am unteren Ende des Dialogs

Question

In meinem benutzerdefinierten Dialogfeld versuche ich, meine Checkbox unter meinem scrollview zu bleiben, aber es funktioniert nicht. Ich habe versucht, das Kontrollkästchen unter der Scrollview in Xml, aber es erscheint nicht, wenn ich die App ausführen. Was muss getan werden, damit das Kontrollkästchen am unteren Rand des Dialogfelds (unterhalb der Bildlaufansicht) bleibt und nicht Teil der Bildlaufansicht ist, wenn ich es blättern lasse? Ich möchte nicht, dass meine Checkbox mit dem Scrollview blättert.

java

LayoutInflater inflater = LayoutInflater.from(this); 
View dialog_layout = inflater.inflate(R.layout.fragment_overlay, (ViewGroup) findViewById(R.id.Overlay_linearLayout)); 
AlertDialog.Builder db = new AlertDialog.Builder(this); 
db.setView(dialog_layout); 
db.setPositiveButton("OK", new DialogInterface.OnClickListener() { 
}); 
db.show();

Answer 1

Try checkbox und ScrolView innerhalb neuer LinearLayout und checkbox wie dies außerhalb des ScrollView setzen zu setzen :

<LinearLayout 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:orientation="vertical"> 

    <ScrollView android:id="@+id/Overlay_scrollView" 
       xmlns:android="http://schemas.android.com/apk/res/android" 
       android:layout_width="fill_parent" 
       android:layout_height="0dp" 
       android:layout_weight="1"> 

     <TableLayout android:id="@+id/Overlay_tableLayout" 
        xmlns:android="http://schemas.android.com/apk/res/android" 
        android:layout_width="fill_parent" 
        android:layout_height="wrap_content" 
        android:weightSum="1.0"> 

       <ImageView 
        android:layout_width="0px" 
        android:layout_height="80dp" 
        android:layout_weight="0.3" 
        android:src="@drawable/ic_launcher"/> 

       <TextView 
        android:id="@+id/MapOverlay_textView0" 
        android:layout_width="0px" 
        android:layout_weight="0.7" 
        android:text="tion0"/> 


       <ImageView 
        android:layout_width="0px" 
        android:layout_height="80dp" 
        android:layout_weight="0.3" 
        android:src="@drawable/ic_launcher"/> 

       <TextView 
        android:id="@+id/MapOverlay_textView1" 
        android:layout_width="0px" 
        android:layout_weight="0.7" 
        android:text="dada"/> 


       <ImageView 
        android:layout_width="0px" 
        android:layout_height="80dp" 
        android:layout_weight="0.3" 
        android:src="@drawable/ic_launcher"/> 

       <TextView 
        android:id="@+id/MapOverlay_textView2" 
        android:layout_width="0px" 
        android:layout_weight="0.7" 
        android:text="ruction2"/> 


       <ImageView 
        android:layout_width="0px" 
        android:layout_height="80dp" 
        android:layout_weight="0.3" 
        android:src="@drawable/ic_launcher"/> 

       <TextView 
        android:id="@+id/MapOverlay_textView3" 
        style="@android:style/TextAppearance.Medium" 
        android:layout_width="0px" 
        android:layout_weight="0.7" 
        android:text="_instruction3"/> 


     </TableLayout> 
    </ScrollView> 

    <CheckBox 
     android:id="@+id/skip" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:text="Don't show this again"/> 
</LinearLayout> 

UPDATE

Wie xml Datei aufzublasen und zu dialog

LayoutInflater inflater = getLayoutInflater(); 
View dialoglayout = inflater.inflate(R.layout.dialog_layout, null); 
AlertDialog.Builder builder = new AlertDialog.Builder(this); 
builder.setView(dialoglayout); 
builder.show();

Versuchen Sie dies für Ihre Layout-Datei festgelegt. Es ist Ihre XML-Datei mit einigen Änderungen.

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
