java–查找Xposed模块的钩子方法

我正在尝试制作一个Xposed模块.
我首先阅读了一个教程,其中包含了操作时钟的指令.
代码如下：

package de.robv.android.xposed.mods.tutorial;
import static de.robv.android.xposed.XposedHelpers.findAndHookMethod;
import android.graphics.Color;
import android.widget.TextView;
import de.robv.android.xposed.IXposedHookLoadPackage;
import de.robv.android.xposed.XC_MethodHook;
import de.robv.android.xposed.callbacks.XC_LoadPackage.LoadPackageParam;
public class Tutorial implements IXposedHookLoadPackage {
public void handleLoadPackage(final LoadPackageParam lpparam) throws Throwable {
if (!lpparam.packageName.equals("com.android.systemui"))
return;
findAndHookMethod("com.android.systemui.statusbar.policy.Clock", lpparam.classLoader, "updateClock", new XC_MethodHook() {
@Override
protected void afterHookedMethod(MethodHookParam param) throws Throwable {
TextView tv = (TextView) param.thisObject;
String text = tv.getText().toString();
tv.setText(text + " :)");
tv.setTextColor(Color.RED);
}
});
}
}


我想现在制作我自己的模块,在输入模式锁之后我必须执行一些操作.进入模式后,我想读取模式并根据模式执行一些操作.
请在这方面帮助我.
我甚至无法确定要挂钩的方法.
我试图在http://grepcode.com/project/repository.grepcode.com/java/ext/com.google.android/android/找到它

谢谢！

解决方法:

我在android git的keyguard源代码中搜索了一下,我找到了this方法,你应该挂钩this方法.在此方法中,您可以在正确的时间直接访问模式.

findAndHookMethod("com.android.internal.widget.LockPatternUtils", lpparam.classLoader, "checkPattern", List.class /*You need to name the attribute's data type, I'm still not sure if List.class is enough, as the type is List*/, new XC_MethodHook() {
@Override
protected void afterHookedMethod(MethodHookParam param) throws Throwable {
List pattern = param.args[0];
// Proceed…
}
});


稍微多一点,我找到了一个静态方法,您可以使用它将模式转换为String以获得更好的可用性：LockPatternUtils.patternToString()

Class[] c = new Class[1];
c[0] = List.class;
XposedHelpers.callStaticMethod(XposedHelpers.findClass("com.android.internal.widget.LockPatternUtils", lpparam.classLoader), "patternToString", c, pattern);
