Android, verhindern ImageButton von Stretching TableLayout

Question

Also, ich versuche, eine benutzerdefinierte Tastatur mit ImageButton in der unteren linken Ecke, aber das Bild weigert sich zu verkleinern, als ob ich mit wrap_content. wrap_content Eigenschaft wird nie verwendet.

Ausgang (was ich will - auf der linken Seite, was ich bekommen haben - auf der rechten Seite):

Answer 1

Ich habe mir ein Problem gestellt. TableRow Element war nicht in der Lage, ein Element im Inneren zu verengen. Also eine Antwort ist - TableRow Element durch LinearLayot zu ersetzen.

Answer 2

Vorschlag: eine Tastatur zu entwerfen, Sie können nur Linearlayout mit geeigneten Werten für das Gewicht und Gewicht Attribut verwenden.

Ihr Bild Taste wie diese in einem Layout Wrap wird

<RelativeLayout android:style="@style/CalculatorButton"> 
         <ImageButton 
          android:id="@+id/imageButton1" 
          android:layout_centerInParent="true" 
          android:layout_width="20dp" 
          android:layout_height="20dp" 
          android:layout_column="2" 
          android:scaleType="fitCenter" 
          android:src="@drawable/hj" /> 
        </RelativeLayout> 

ursprüngliche Höhe des Bildes betrachtet werden. Also gib besser die Breite und Höhe des Bildes an.
