先看下效果：

寫個進度條調用類：

package com.xiayiye.yhsh.flowerdialog;import android.app.Activity; import android.app.AlertDialog; import android.content.Context; import android.content.DialogInterface;/*** 網絡請求加載對話框以及普通的alertDialog*/ public class DialogUtils {private Context mContext;private LoadingDialog loadingDialog;public DialogUtils(Context context) {this.mContext = context;}/*** 顯示菊花以及菊花下方的文字提示，點擊外部不可取消，點擊返回可以取消* 不接收回調接收回調*/public void showLoadingWithLabel(String text) {loadingDialog = LoadingDialog.create(mContext).setLabel(text).show();}/*** 顯示菊花以及菊花下方的文字提示，點擊外部不可取消，點擊返回可以取消* 接收回調*/public void showLoadingWithLabel(String text, DialogInterface.OnCancelListener onCancelListener) {loadingDialog = LoadingDialog.create(mContext).setLabel(text).setCancellableListener(onCancelListener).show();}/*** @Param cancelable 設置為false 返回按鈕不可用 若為true 直接調用{@link #showLoadingWithLabel}的監聽方法* 顯示菊花以及菊花下方的文字提示，點擊外部不可取消，點擊返回可以取消* 不接收回調接收回調*/public void showLoadingWithLabel(String text, boolean cancelable) {loadingDialog = LoadingDialog.create(mContext).setLabel(text).setCancellable(cancelable).show();}/*** 僅顯示一個菊花 不接收取消回調* 默認點擊外部不可取消 ，點擊返回按鈕可以dismiss*/public void showLoading() {loadingDialog = LoadingDialog.create(mContext).show();}/*** 僅顯示一個菊花 并且有 cancel回調* 默認點擊外部不可取消 ，點擊返回按鈕可以dismiss*/public void showLoading(DialogInterface.OnCancelListener onCancelListener) {loadingDialog = LoadingDialog.create(mContext).setCancellableListener(onCancelListener).show();}/*** @Param cancelable 設置為false 返回按鈕不可用 若為true 直接調用{@link #showLoading}的監聽方法* 顯示菊花，點擊外部不可取消* 不接收回調*/public void showLoading(boolean cancelable) {loadingDialog = LoadingDialog.create(mContext).setCancellable(cancelable).show();}/*** dismiss*/public void dismissLoading() {if (loadingDialog!=null)loadingDialog.dismiss();}/*** 無title 一個positivebutton 點擊外部以及返回按鈕均不可取消* 點擊button消失** @param message* @param textPositiveButton* @param onDismissListener null時不監聽dismiss*/public void showAlertDialog(String message, String textPositiveButton, DialogInterface.OnDismissListener onDismissListener) {if(!((Activity) mContext).isFinishing()) {new AlertDialog.Builder(mContext).setCancelable(false).setMessage(message).setPositiveButton(textPositiveButton, new DialogInterface.OnClickListener() {@Overridepublic void onClick(DialogInterface dialog, int which) {dialog.dismiss();}}).setOnDismissListener(onDismissListener).show();}}}

2.工具類里面涉及到的LoadingDialog類如下：

package com.xiayiye.yhsh.flowerdialog;import android.annotation.SuppressLint; import android.app.Dialog; import android.content.Context; import android.content.DialogInterface; import android.graphics.Color; import android.graphics.drawable.ColorDrawable; import android.os.Bundle; import android.view.Gravity; import android.view.View; import android.view.ViewGroup; import android.view.Window; import android.view.WindowManager;

LoadingDialog涉及到的BackgroundLayout類

package com.xiayiye.yhsh.flowerdialog;import android.annotation.TargetApi; import android.content.Context; import android.graphics.drawable.GradientDrawable; import android.os.Build; import android.util.AttributeSet; import android.widget.LinearLayout;/*** from https://github.com/Kaopiz/KProgressHUD* 增加了一個正方形顯示* update minionshuang*/ public class BackgroundLayout extends LinearLayout {private float mCornerRadius;private int mBackgroundColor;public BackgroundLayout(Context context) {super(context);init();}public BackgroundLayout(Context context, AttributeSet attrs) {super(context, attrs);init();}@TargetApi(Build.VERSION_CODES.HONEYCOMB)public BackgroundLayout(Context context, AttributeSet attrs, int defStyleAttr) {super(context, attrs, defStyleAttr);init();}@SuppressWarnings("deprecation")private void init() {int color = getContext().getResources().getColor(R.color.colorLoadingProgressBg);initBackground(color, mCornerRadius);}private void initBackground(int color, float cornerRadius) {GradientDrawable drawable = new GradientDrawable();drawable.setShape(GradientDrawable.RECTANGLE);drawable.setColor(color);drawable.setCornerRadius(cornerRadius);if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {setBackground(drawable);} else {setBackgroundDrawable(drawable);}}public void setCornerRadius(float radius) {mCornerRadius = ScaleUtils.dip2px(radius);initBackground(mBackgroundColor, mCornerRadius);}public void setBaseColor(int color) {mBackgroundColor = color;initBackground(mBackgroundColor, mCornerRadius);}//正方形顯示@Overrideprotected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {super.onMeasure(widthMeasureSpec, heightMeasureSpec);int width = getMeasuredWidth();int height = getMeasuredHeight();int size = Math.max(width, height);setMeasuredDimension(size, size);} }

BackgroundLayout里面涉及到的尺寸工具類ScaleUtils

package com.xiayiye.yhsh.flowerdialog;import android.content.res.Resources;/*** dp px sp 轉化工具**/ public class ScaleUtils {private ScaleUtils() {}public static int dip2px(float f) {return Math.round((Resources.getSystem().getDisplayMetrics().density * f) + 0.5f);}public static int px2dip(float f) {return Math.round((f / Resources.getSystem().getDisplayMetrics().density) + 0.5f);}public static int px2sp(float f) {return Math.round((f / Resources.getSystem().getDisplayMetrics().scaledDensity) + 0.5f);}public static int sp2px(float f) {return Math.round((Resources.getSystem().getDisplayMetrics().scaledDensity * f) + 0.5f);}}
