我正在文本视图中添加复制粘贴功能.我已经添加了代码registerForContextMenu(detailedText);还有
android:textIsSelectable =“true”在xml.When我试图复制它工作得很好,但当它指向文本视图的第一个位置,而不是我们尝试选择文本,它会抛出错误,我显示如下.我该怎么解决呢?请帮帮我.
<TextView android:id="@+id/datailtext" android:layout_width="match_parent" android:layout_height="wrap_content" android:textIsSelectable="true" android:layout_below="@+id/EMPTY" android:text="@string/detailed_text" />

更新代码
好吧,我想在文本视图Android 2.3上实现复制粘贴功能,我已经做了这么远的代码,我详细的下面.有更好的建议在Android 2.3中实现请帮助我.
detailedText.setOnLongClickListener(new OnLongClickListener() { @SuppressLint("NewApi") @Override public boolean onLongClick(View v) { // TODO Auto-generated method stub Log.d("LOG","Detail text long pressed"); int startIndex = detailedText.getSelectionStart(); int endIndex = detailedText.getSelectionEnd(); Log.d("LOG","startIndex "+ startIndex + "endIndex " + endIndex);///here get index -1,-1 for startIndex and endIndex in less than android 4.4 i dont know why? String YouExtracted = stringYouExtracted.substring(startIndex,endIndex); int sdk = android.os.Build.VERSION.SDK_INT; if (sdk < android.os.Build.VERSION_CODES.HONEYCOMB) { android.text.ClipboardManager clipboard = (android.text.ClipboardManager) getSystemService(Context.CLIPBOARD_SERVICE); clipboard.setText(detailedText.getText().toString()); } else { android.content.ClipboardManager clipboard = (android.content.ClipboardManager) getSystemService(Context.CLIPBOARD_SERVICE); android.content.ClipData clip = android.content.ClipData .newPlainText("COPYTEXT",detailedText.getText().toString()); clipboard.setPrimaryClip(clip); } return true; } }); setupSocialNetworkingLinks(); } /*@Override public void onCreateContextMenu(ContextMenu menu,View v,ContextMenuInfo menuInfo) { //user has long pressed your TextView menu.add(0,v.getId(),"COPYTEXT"); //cast the received View to TextView so that you can get its text TextView yourTextView = (TextView) detailedText; int startIndex = detailedText.getSelectionStart(); int endIndex = detailedText.getSelectionEnd(); String YouExtracted = detailedText.getText().toString(); //place your TextView's text in clipboard if(android.os.Build.VERSION.SDK_INT < android.os.Build.VERSION_CODES.HONEYCOMB) { android.text.ClipboardManager clipboard = (android.text.ClipboardManager) getSystemService(Context.CLIPBOARD_SERVICE); clipboard.setText(YouExtracted); } else { android.content.ClipboardManager clipboard = (android.content.ClipboardManager) getSystemService(Context.CLIPBOARD_SERVICE); android.content.ClipData clip = android.content.ClipData.newPlainText("COPYING",YouExtracted); clipboard.setPrimaryClip(clip); } } */
解决方法
这有点迟了,但是你使用的是自定义的LinkMovementMethod?我发现了相同的异常,但是一旦我将setCustomMovementMethod注释出来,异常就会消失.
不知道为什么会发生这种情况.
