Add the widget to your layout
<az.plainpie.PieView
android:id="@+id/pieView"
android:layout_width="200dp"
android:layout_height="200dp"
plainpie:inner_pie_padding="30"
plainpie:percentage="75"
plainpie:percentage_size="70"
plainpie:inner_text_visibility="true"/>Remember to add a namespace for the library in your layout:
xmlns:plainpie="http://schemas.android.com/apk/res-auto"You can customize the widget from the layout file, or from the activity once you obtain a reference to it:
PieView pieView = (PieView) findViewById(R.id.pieView);
pieView.setPercentageBackgroundColor(getResources().getColor(R.color.customColor2));
pieView.setInnerText("A");
You can animate the fill of the percentage bar:
PieView animatedPie = (PieView) findViewById(R.id.animated_pie_view_1);
PieAngleAnimation animation = new PieAngleAnimation(animatedPie);
animation.setDuration(5000);
//This is the duration of the animation in millis animatedPie.startAnimation(animation);
You can update any color of the widget:
PieView pieView = (PieView) findViewById(R.id.pieView);
// Change the color fill of the bar representing the current percentage pieView.setPercentageBackgroundColor(getResources().getColor(R.color.customColor1));
// Change the color fill of the background of the widget, by default is transparent pieView.setMainBackgroundColor(getResources().getColor(R.color.customColor5));
// Change the color of the text of the widget pieView.setTextColor(getResources().getColor(R.color.customColor12));
If required you can also change the area covered by the inner circle of the widget to change its appearence:
PieView pieView = (PieView) findViewById(R.id.pieView);
// Change the thickness of the percentage bar pieView.setPieInnerPadding(50);
And finally update the text if you want the widget to represent other thing or even toggle the visibility of its center text:
PieView pieView = (PieView) findViewById(R.id.pieView);
// Update the visibility of the widget text pieView.setInnerTextVisibility(View.VISIBLE);
// Change the text of the widget pieView.setInnerText("A");
// Change the text size of the widget pieView.setPercentageTextSize(35);
| Without inner text | With a label instead of a percentage |
