我正在开发一个Android应用程序，我正在从我的另一个类2扩展我的类1，并且其他类2从片段扩展。当我尝试使用intent从类1调用其他类时，我得到错误。我还在Manifest文件中注册了新类。 名为抽象片段的第1类是：
public abstract class AbstractFragment extends Fragment implements IFragment {
/**
* Fragment title
*/
private String mTitle;
/**
* Enable or not the fragment
*/
protected boolean mEnable;
/**
* Setter for the field mTitle
*
* @param mTitle
* the mTitle to set
*/
public void setTitle(final String mTitle) {
this.mTitle = mTitle;
}
/**
* Setter for the field mEnable
*
* @param mEnable
* the mEnable to set
*/
public void setEnable(final boolean mEnable) {
this.mEnable = mEnable;
}
@Override
public String getTitle() {
return mTitle;
}
@Override
public boolean isEnable() {
return mEnable;
}
}
Class 2，其名称为CardDetailFragment：
public class CardDetailFragment extends AbstractFragment {
/**
* Card to display
*/
private EmvCard mCard;
/**
* Empty view
*/
private LinearLayout mEmptyView;
/**
* Card view
*/
private ScrollView mScrollView;
/**
* Card number
*/
private TextView mCardNumber;
/**
* Card validity
*/
private TextView mCardValidity;
/**
* Image view
*/
private ImageView mImageView;
/**
* Extended layout
*/
private TableLayout mExtendedLayout;
/**
* Method used to create a new instance of the fragment
*
* @param pCard
* EmvCard
* @param pTitle
* fragment title
* @return fragment
*/
Button pay;
public static IFragment newInstance(final EmvCard pCard, final String pTitle) {
CardDetailFragment ret = new CardDetailFragment();
ret.setEnable(true);
ret.setTitle(pTitle);
ret.setCard(pCard);
return ret;
}
@Override
public View onCreateView(final LayoutInflater inflater, final ViewGroup container, final Bundle savedInstanceState) {
return inflater.inflate(R.layout.card_detail, container, false);
}
@Override
public void onViewCreated(final View view, final Bundle savedInstanceState) {

// Set OCR-A typeface

pay=(Button)view.findViewById(R.id.button1);
pay.setBackgroundColor(Color.BLACK);
pay.setTextColor(Color.WHITE);
// Update content
updateContent();
pay.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent in = new Intent(getActivity(),CaptureSignature.class);
startActivity(in);
}
});
}
/**

*/
private void updateContent() {
if (getActivity() != null) {
if (mCard != null) {
mEmptyView.setVisibility(View.GONE);
mScrollView.setVisibility(View.VISIBLE);
// Update content
mCardNumber.setText(CardUtils.formatCardNumber(mCard.getCardNumber(), mCard.getType()));
SimpleDateFormat format = new SimpleDateFormat("MM/yy", Locale.getDefault());
mCardValidity.setText(format.format(mCard.getExpireDate()));
mImageView.setImageResource(CardUtils.getResourceIdCardType(mCard.getType()));
// Extended card data

}
// card AID
if (StringUtils.isNotEmpty(mCard.getAid())) {
createRaw(getString(R.string.extended_title_AID), CardUtils.formatAid(mCard.getAid()));
}
// Card Application label
if (StringUtils.isNotEmpty(mCard.getApplicationLabel())) {
createRaw(getString(R.string.extended_title_application_label), mCard.getApplicationLabel());
}

}
// Pin try left
createRaw(getString(R.string.extended_title_pin_try), mCard.getLeftPinTry() + " "
+ getString(R.string.extended_title_times));
// Atr desc
if (mCard.getAtrDescription() != null && !mCard.getAtrDescription().isEmpty()) {
createRaw(getString(R.string.extended_title_possible_bank), StringUtils.join(mCard.getAtrDescription(), "\n"));
}
} else {
mEmptyView.setVisibility(View.VISIBLE);
mScrollView.setVisibility(View.GONE);
}
}
}
/**
* Method used to create a row in the section "Extended card detail"
*
* @param pKeyName
* key title
* @param pValue
* key value
*/
private void createRaw(final String pKeyName, final String pValue) {
View v = View.inflate(getActivity(), R.layout.tablelayout_raw, null);
TextView title = (TextView) v.findViewById(R.id.extended_raw_title);
title.setText(pKeyName);
TextView content = (TextView) v.findViewById(R.id.extended_raw_content);
content.setText(pValue);
mExtendedLayout.addView(v);
}
public void update(final EmvCard pCard) {
mCard = pCard;
updateContent();
}
/**

*

*/
public void setCard(final EmvCard mCard) {
this.mCard = mCard;
}

我试图调用的类名为CaptureSignature。 错误日志是：

答案 0 :(得分：0)
更改此
<activity android:name=".activity.CaptureSignature"></activity>
到这个
<activity android:name=".fragment.viewPager.impl.CaptureSignature"></activity>
或提供您的活动的完整路径
<activity android:name="com.github.devnied.emvnfccard.fragment.viewPager.impl.CaptureSignature"></activity>
