2.Action Process Button

操作指南
https://github.com/dmytrodanylyk/android-process-button/wiki/User-Guide#action-process-button
xml佈局：

<com.dd.processbutton.iml.ActionProcessButton
    android:id="@+id/btnSignIn"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginBottom="16dp"
    android:text="Sign_in"
    android:textColor="@android:color/white"
    android:textSize="18sp"
    custom:pb_colorComplete="@color/green_complete"    //setprogress(100)
    custom:pb_colorNormal="@color/blue_normal"             //setprogress(0)
    custom:pb_colorPressed="@color/blue_pressed"          //
    custom:pb_colorProgress="@color/purple_progress"
    custom:pb_textComplete="Success"
    custom:pb_textProgress="Loading"
    custom:pb_textError="Error"
    custom:pb_colorError="@color/red_error" />
 

custom:pb_colorComplete="@color/green_complete"會報錯的話參考
xmlns:custom=“http://schemas.android.com/apk/res-auto”
例如：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              xmlns:tools="http://schemas.android.com/tools"
              android:layout_width="match_parent"
              android:layout_height="match_parent"
              xmlns:app="http://schemas.android.com/apk/res-auto"
              xmlns:custom="http://schemas.android.com/apk/res-auto"
              android:orientation="vertical">
        <!--進度為[100]時顯示的背景顏色-->
        custom:pb_colorComplete
        <!--進度為[100]時顯示的文字-->
        custom:pb_textComplete
        <!--l載入進度為[1-99]時顯示的顏色]-->
        custom:pb_colorProgress
        <!--進度為[1-99]時顯示的文字]-->
        custom:pb_textProgress
        <!--當進度為[-1]時將顯示的文字-->
        custom:pb_textError="Error"
        <!--進度為[-1]時顯示的背景顏色-->
        custom:pb_colorComplete
 

通過Java程式碼控制它

ActionProcessButton btnSignIn = (ActionProcessButton) findViewById(R.id.btnSignIn);
btnSignIn.setMode(ActionProcessButton.Mode.PROGRESS);

//有進度的進度條
// no progress
button.setProgress(0);
// progressDrawable cover 50% of button width, progressText is shown
button.setProgress(50);
// progressDrawable cover 75% of button width, progressText is shown
button.setProgress(75);
// completeColor & completeText is shown
button.setProgress(100);

//顯示無盡進度條
btnSignIn.setMode(ActionProcessButton.Mode.ENDLESS);
// 設定進度> 0以啟動進度指示器動畫
button.setProgress(1);
