使用说明：

Usage

Declare button inside your layout XML file:

<com.dd.CircularProgressButton
    android:id="@+id/btnWithText"
    android:layout_width="196dp"
    android:layout_height="64dp"
    android:layout_marginTop="16dp"
    android:textColor="@color/white"
    android:textSize="18sp"
    app:textComplete="@string/Complete"
    app:textError="@string/Error"
    app:textIdle="@string/Upload" />

Button state depends on progress:

• normal state [0]
• progress state [1-99]
• success state [100]
• error state [-1]

To change progress use CircularProgressButton.setProgress(int value) method.

Idle state

CircularProgressButton.setProgress(0)

• To change text app:textIdle="@string/Upload"
• To change background color app:colorIdle="@color/green"

Progress state 1

CircularProgressButton.setProgress(1) will automatically morph button from idle (square shape) state to progress (circle shape) state.

To change indicator color app:colorIndicator="@color/blue"

To change indicator background color app:colorIndicatorBackground="@color/grey"

To change circle background color app:colorProgress="@color/white"

Progress state 50

CircularProgressButton.setProgress(50)

Complete state 100

CircularProgressButton.setProgress(-1)

• To change text app:textError="@string/Error"
• To change background color app:colorError="@color/red"

Error state -1

CircularProgressButton.setProgress(-1)

• To change text app:textComplete="@string/Complete"
• To change background color app:colorComplete="@color/green"

You can set rounded corners

app:cornerRadius="48dp"

You can use icons for complete & error states

app:iconComplete="@drawable/ic_action_accept"

app:iconError="@drawable/ic_action_cancel"
