android之修改系统自带ProgressDialog样式

1.ProgressDialog默认样式是当前Activity的theme所定义的ProgressDialog样式。

继承自父类AlertDialog的style.

AlertDialog的源码

     static int resolveDialogTheme(Context context, int resid) {        if (resid == THEME_TRADITIONAL) {            return com.android.internal.R.style.Theme_Dialog_Alert;        } else if (resid == THEME_HOLO_DARK) {            return com.android.internal.R.style.Theme_Holo_Dialog_Alert;        } else if (resid == THEME_HOLO_LIGHT) {            return com.android.internal.R.style.Theme_Holo_Light_Dialog_Alert;        } else if (resid == THEME_DEVICE_DEFAULT_DARK) {            return com.android.internal.R.style.Theme_DeviceDefault_Dialog_Alert;        } else if (resid == THEME_DEVICE_DEFAULT_LIGHT) {            return com.android.internal.R.style.Theme_DeviceDefault_Light_Dialog_Alert;        } else if (resid >= 0x01000000) {   // start of real resource IDs.            return resid;        } else {            TypedValue outValue = new TypedValue();            context.getTheme().resolveAttribute(com.android.internal.R.attr.alertDialogTheme,                    outValue, true);            return outValue.resourceId;        }    }

2.引用系统的样式，引用不到com.android.internal.R.style.Theme_Holo_Dialog_Alert，而是通过ProgressDialog.THEME_HOLO_LIGHT来引用系统自定义ProgressDialog样式。

ProgressDialog dialog = new ProgressDialog(this, ProgressDialog.THEME_HOLO_LIGHT);
dialog.setTitle("登录");
dialog.setMessage("正在登录，请稍后...");
// dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setCanceledOnTouchOutside(false);
dialog.setCancelable(true);
dialog.show();

3.引用自定义ProgressDialog样式
