I have a requirement where I need to show a bar at the bottom of the screen on particu开发者_StackOverflow中文版lar event in the background thread. Also it has to be clickable.
I could consider showing a toast but toasts are not clickable. How can this be done? Im developing on 2.1May be it is useful for you. in layout file write this
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:gravity="bottom"
android:paddingLeft="5px"
android:paddingTop="5px"
android:paddingRight="5px">
<packagename.TransparentPanel
android:id="@+id/transparent_panel"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:paddingTop="5px"
android:paddingLeft="5px"
android:paddingBottom="5px"
android:paddingRight="5px">
<Button android:id="@+id/button_click_me"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Click Me!"/>
</packagename.TransparentPanel>
and create TransparentPanel in your package
public class TransparentPanel extends LinearLayout
{
private Paint innerPaint, borderPaint ;
public TransparentPanel(Context context, AttributeSet attrs) {
super(context, attrs);
init();
}
public TransparentPanel(Context context) {
super(context);
init();
}
private void init() {
innerPaint = new Paint();
innerPaint.setARGB(225, 75, 75, 75);
innerPaint.setAntiAlias(true);
borderPaint = new Paint();
borderPaint.setARGB(255, 255, 255, 255);
borderPaint.setAntiAlias(true);
borderPaint.setStyle(Style.STROKE);
borderPaint.setStrokeWidth(2);
}
public void setInnerPaint(Paint innerPaint) {
this.innerPaint = innerPaint;
}
public void setBorderPaint(Paint borderPaint) {
this.borderPaint = borderPaint;
}
@Override
protected void dispatchDraw(Canvas canvas) {
RectF drawRect = new RectF();
drawRect.set(0,0, getMeasuredWidth(), getMeasuredHeight());
canvas.drawRoundRect(drawRect, 5, 5, innerPaint);
canvas.drawRoundRect(drawRect, 5, 5, borderPaint);
super.dispatchDraw(canvas);
}
}
set this where you need.
You can display a dialog and change de android:background to android:background="@android:drawable/toast_frame"
If you want the same style you can use a layout With the toast's background and then apply it a animation that make the layout grow from button.
I will show a PopupWindow for a notification on top of the current activity. Found it through Google. Thanks to all for your replies.
