POandroid :Customizing Button with dynamic values
text
Body
copied!<p>I want to customize Buttons for my application. The application has a color picker where the user will select color and I have to set that particular start/end color to the buttons. These colro values will be stored in an object "Utility". </p> <p>Basically from start only, I want to use "Utility" object to set colors for background, text color, font, etc. And again when the color is changed by the user I got to change it to the buttons and refresh them. And also to save colors in a file, so next time user starts app, it comes up with the last color selected. </p> <p>I couldn't find <code><selector></code> to be the best option, as I wont be able to change the color in xml. What can be the best option for such requirement ?</p> <p><strong>UPDATIONS :</strong> @jitendra, from your answer I got somethign helpful. I use GradientDrawable to set colors of my buttons. In my onCreate() of the Activity, I call a method RefreshComponents() that sets the background of root, text color/size of buttons and gradient colors of the buttons. It works properly, but the only problem I see is the on applying GradientDrawable to the button the gap between 2 buttons is lost. </p> <p>This is the image WITHOUT applying GradientDrawable : <img src="https://i.stack.imgur.com/bL7EU.png" alt="enter image description here"></p> <p><strong>On applying GradientDrawable the output is :</strong> <img src="https://i.stack.imgur.com/Byg4n.png" alt="enter image description here"></p> <p>You see the size of button is increased a bit from all the sides. If I apply to next button also, they both touch eachother. My xml for the above is :</p> <pre><code><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/mainroot" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" android:paddingTop="35dip" android:paddingBottom="35dip" android:paddingLeft="35dip" android:paddingRight="35dip"android:gravity="center" > <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/mainrow1" android:layout_width="fill_parent" android:layout_height="wrap_content" android:orientation="horizontal" android:layout_marginBottom="15dip" android:gravity="center_horizontal" > <Button android:text="Accounting" android:id="@+id/accBtn" android:layout_width="80dip" style="@style/TileButtonStyle" /> <Button android:text="Data" android:id="@+id/dataBtn" android:layout_width="80dip" android:layout_height="fill_parent"></Button> <Button android:text="Information" android:id="@+id/infoBtn" android:layout_width="80dip" android:layout_height="fill_parent" android:ellipsize="end"></Button> </LinearLayout> ..... Other lineasr layout with same parameters as above child </code></pre> <p>And the GradientDrawable that I create is :</p> <pre><code> public static GradientDrawable getButtonDrawable(Button btn) { int colors[] = {getStartColor(), getEndColor()}; GradientDrawable grad = new GradientDrawable(GradientDrawable.Orientation.LEFT_RIGHT, colors); grad.setCornerRadius(5f); return grad; } </code></pre> <p>And finally in my onCreate(), I add :</p> <pre><code> GradientDrawable btnGradient = Utility.getButtonDrawable(btn1); btn1.setBackgroundDrawable(btnGradient); </code></pre> <p>What is going wrong here ? Is the margin around the button becoming 0 ? Do I have to set bounds for the grad, or again set LayoutParams for the button ? </p> <p>Any help is appreciative to help me achieve my goal.</p> <p>Thanks</p>
