如何以编程方式更改主屏幕小部件的形状颜色

Question

I want my homescreen widget to be a rectangle with corners so I have a shape drawable. The solid color, however, needs to change on the press of a button to match my text background color. I am able to change my text background color in this way:

RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.widget);

backgroundColor = colors[mCounter];
views.setInt(R.id.appwidget_text, "setBackgroundColor", backgroundColor);

I tried the following but no luck:

views.setInt(R.drawable.layout_bg, "setBackgroundColor", backgroundColor);

I have also tried changing the backgroundTint of my widget, and the following:

views.setInt(R.id.appwidget_layout, "setBackgroundTint", backgroundColor);

This does not do anything either.

Is there a solution?

Answer 1

int[] color = new int[2];
color[0] = Color.parseColor("#000000");
color[1] = Color.parseColor("#000000");

View view = new RelativeLayout(this);
GradientDrawable drawable = (GradientDrawable) view.getBackground();

drawable.setColors(color);

try this. for your problem,

int[] color = new int[2];
color[0] = Color.parseColor("#000000");
color[1] = Color.parseColor("#000000");
GradientDrawable drawable = (GradientDrawable) views.getBackground();
drawable.setColors(color);

hope it will helps. :)
