一、在基类Help.cpp文件中加入：
int copyToClipboard(const std::string& paras) {
#if (CC_TARGET_PLATFORM == CC_PLATFORM_ANDROID)
JniMethodInfo minfo;
if (JniHelper::getStaticMethodInfo(minfo, "org/cocos2dx/cpp/AppActivity","copyToClipboard", "(Ljava/lang/String;)I"))
{
jstring jstr = minfo.env->NewStringUTF(paras.c_str());
int code = minfo.env->CallStaticIntMethod(minfo.classID, minfo.methodID, jstr);
return code;
}
#endif
return -1;
}
二、在Help.h中加入：
//复制到剪贴板
int copyToClipboard(const std::string& paras);
三、在需要调用的地方直接调用，比如按下一个按钮复制：
void Spread::buttonEventWithCopy(cocos2d::Ref *ref, cocos2d::ui::Widget::TouchEventType type)
{
if (type == cocos2d::ui::Widget::TouchEventType::ENDED)
{
copyToClipboard("copytext");
}
}
四、编辑安卓包下org/cocos2dx/cpp/AppActivity.java文件
public class AppActivityextends Cocos2dxActivity {
static AppActivitysgsActivity;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
sgsActivity =this;
}
//参数要加final关键字，否则内部类不能访问
static public int copyToClipboard(final String text) {
final Context context =sgsActivity;//参数要加final关键字，否则内部类不能访问
try {
Log.d("cocos2dx","copyToClipboard " + text);
Runnable runnable =new Runnable() {
public void run() {
android.content.ClipboardManager clipboard = (android.content.ClipboardManager)context.getSystemService(Context.CLIPBOARD_SERVICE);
android.content.ClipData clip = android.content.ClipData.newPlainText("Copied Text",text);
clipboard.setPrimaryClip(clip);
}
};
//getSystemService运行所在线程必须执行过Looper.prepare()
//否则会出现Can't create handler inside thread that has not called Looper.prepare()
sgsActivity.runOnUiThread(runnable);
}catch (Exception e) {
Log.d("cocos2dx","copyToClipboard error");
e.printStackTrace();
return -1;
}
return 0;
}
}
