我正在使用pass sdk v1.2.1，根据programming guide，有一种方法可以更改指纹对话框中显示的待机文本。该指南说您必须检查功能A star (*) next to a name means that the command is disabled.
是否可以调用Spass.DEVICE_FINGERPRINT_AVAILABLE_PASSWORD，如下所示：
changeStandbyString我尝试在带有Android 6.0和Galaxy S5 Android 5.x.x的Galaxy S5上使用它我都得到了异常
if(pass.isFeatureEnabled(Spass.DEVICE_FINGERPRINT_AVAILABLE_PASSWORD)) {
mSpassFingerprint.changeStandbyString("Touch your fingerprint or press the button for launching own menu”);
}
看起来有点奇怪的是，如果IllegalStateException: setStandbyString is not supported.
中的方法返回true，则会调用异常，结果与检查时调用的方法相同
changeStandbyString看起来好像有什么不对，有什么想法吗？
这是使用android studio调试时生成的代码：
isFeatureEnabled(Spass.DEVICE_FINGERPRINT_AVAILABLE_PASSWORD);
请注意，方法public void changeStandbyString(String var1) {
this.f();
if(this.d()) {
throw new IllegalStateException("setStandbyString is not supported.");
} else if(var1 == null) {
throw new IllegalArgumentException("the standby text passed is null.");
} else if(var1.length() > 100) {
throw new IllegalArgumentException("the standby text passed is longer than 100 characters.");
} else {
this.m = var1;
}
}
public boolean isFeatureEnabled(int var1) {
if(this.a == null) {
throw new IllegalStateException("initialize() is not Called first.");
} else {
switch(var1) {
case 0:
return this.a.a();
case 1:
case 2:
return this.a.b();
case 3:
return this.a.c();
case 4:
return this.a.d();
default:
throw new IllegalArgumentException("type passed is not valid");
}
}
}
是在两种情况下调用的方法，当您检查要素以查看是否启用以及何时更改文本时，d()看起来应该{ {1}}，就像其他方法一样：
if(!this.d())此处changeStandbyString仅在public void setDialogTitle(String var1, int var2) {
this.f();
if(!this.b()) {
throw new IllegalStateException("setDialogTitle is not supported.");
} else if(var1 == null) {
throw new IllegalArgumentException("the titletext passed is null.");
} else if(var1.length() > 256) {
throw new IllegalArgumentException("the title text passed is longer than 256 characters.");
} else if(var2 >>> 24 != 0) {
throw new IllegalArgumentException("alpha value is not supported in the titleColor.");
} else {
this.f = var1;
this.g = var2 + -16777216;
}
}
返回false时发生，这是throw new IllegalStateException("setDialogTitle is not supported."); this.b()时isFeaturedEnabled调用的方法。

编程指南doc是错误的。如果isFeatureEnabled(Spass. DEVICE_FINGERPRINT_AVAILABLE_PASSWORD)返回false，则可以激活此功能。您可以查看code samples，详细了解如何使用此功能。
