你可以编码你从视图中进行选择，并复制到剪贴板中的文本。 然后，如果您将该代码粘贴到任何其他应用程序中，则只能看到编码的字符串。 在您的应用程序，你需要粘贴到您的视图之前对数据进行解码

在这里，我将提供代码来支持我的发言：

public class MainActivity extends Activity {

EditText editText;

private ClipboardManager myClipboard;

private ClipData myClip;

String base64;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

myClipboard = (ClipboardManager) getSystemService(CLIPBOARD_SERVICE);

editText = (EditText) findViewById(R.id.editText3);

editText.setCustomSelectionActionModeCallback(new Callback() {

@Override

public boolean onPrepareActionMode(ActionMode mode, Menu menu) {

// TODO Auto-generated method stub

return false;

}

@Override

public void onDestroyActionMode(ActionMode mode) {

// TODO Auto-generated method stub

}

@Override

public boolean onCreateActionMode(ActionMode mode, Menu menu) {

// TODO Auto-generated method stub

return true;

}

@Override

public boolean onActionItemClicked(ActionMode mode, MenuItem item) {

// TODO Auto-generated method stub

switch (item.getItemId()) {

case android.R.id.copy:

int min = 0;

int max = editText.getText().length();

if (editText.isFocused()) {

final int selStart = editText.getSelectionStart();

final int selEnd = editText.getSelectionEnd();

min = Math.max(0, Math.min(selStart, selEnd));

max = Math.max(0, Math.max(selStart, selEnd));

}

// Perform your definition lookup with the selected text

final CharSequence selectedText = editText.getText()

.subSequence(min, max);

String text = selectedText.toString();

byte[] data = null;

try {

data = text.getBytes("UTF-8");

} catch (UnsupportedEncodingException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

base64 = Base64.encodeToString(data, Base64.DEFAULT);

myClip = ClipData.newPlainText("text", base64);

myClipboard.setPrimaryClip(myClip);

Toast.makeText(getApplicationContext(), "Text Copied",

Toast.LENGTH_SHORT).show();

// Finish and close the ActionMode

mode.finish();

return true;

case android.R.id.cut:

return true;

case android.R.id.paste:

int min2 = 0;

int max2 = editText.getText().length();

if (editText.isFocused()) {

final int selStart = editText.getSelectionStart();

final int selEnd = editText.getSelectionEnd();

min2 = Math.max(0, Math.min(selStart, selEnd));

max2 = Math.max(0, Math.max(selStart, selEnd));

}

// Perform your definition lookup with the selected text

final CharSequence selectedText2 = editText.getText()

.subSequence(min2, max2);

String text2 = selectedText2.toString();

ClipData abc = myClipboard.getPrimaryClip();

ClipData.Item item11 = abc.getItemAt(0);

String text1 = item11.getText().toString();

byte[] dataDecode = Base64.decode(text1, Base64.DEFAULT);

String textDecode = null;

try {

textDecode = new String(dataDecode, "UTF-8");

} catch (UnsupportedEncodingException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

editText.getText().replace(min2, max2, textDecode, 0,

textDecode.length());

Toast.makeText(getApplicationContext(), "Text Pasted",

Toast.LENGTH_SHORT).show();

// mode.finish();

return true;

default:

break;

}

return false;

}

});

}

}

这里我试图重写它出现在行动中复制和粘贴方法当用户长时间点击EditText栏时， 我的解决方案是隐藏其他应用程序中的数据的替代方法。

粘贴弹出当你在文本插入手柄和粘贴选项，然后单击当您选择一些文本和长点击它说到这，都是从我的观察不同出现。

为了用浆糊弹出的工作，我创建了一个自定义的EditText类和I类定义做所需的任务的方法。这是...

/**

* An EditText, which notifies when something was cut/copied/pasted inside it.

*/

public class MonitoringEditText extends EditText {

private final Context context;

private ClipboardManager myClipboard;

String base64;

EditText editText = (EditText) findViewById(R.id.editText3);

/*

* Just the constructors to create a new EditText...

*/

public MonitoringEditText(Context context) {

super(context);

this.context = context;

}

public MonitoringEditText(Context context, AttributeSet attrs) {

super(context, attrs);

this.context = context;

}

public MonitoringEditText(Context context, AttributeSet attrs, int defStyle) {

super(context, attrs, defStyle);

this.context = context;

}

@Override

public boolean onTextContextMenuItem(int id) {

myClipboard = (ClipboardManager) context

.getSystemService(Context.CLIPBOARD_SERVICE);

boolean consumed = super.onTextContextMenuItem(id);

switch (id) {

// case android.R.id.cut:

// onTextCut();

// break;

case android.R.id.paste: // here I am catching that pop up paste event

try {

onTextPaste();

} catch (UnsupportedEncodingException e1) {

// TODO Auto-generated catch block

e1.printStackTrace();

}

break;

// case android.R.id.copy:

// onTextCopy();

//

}

return consumed;

}

// /**

// * Text was pasted into the EditText.

// * @throws UnsupportedEncodingException

// */

public void onTextPaste() throws UnsupportedEncodingException {

int min2 = 0;

int max2 = editText.getText().length();

if (editText.isFocused()) {

final int selStart = editText.getSelectionStart();

final int selEnd = editText.getSelectionEnd();

min2 = Math.max(0, Math.min(selStart, selEnd));

max2 = Math.max(0, Math.max(selStart, selEnd));

}

ClipData abc = myClipboard.getPrimaryClip();

ClipData.Item item = abc.getItemAt(0);

String text = item.getText().toString(); //text is my encoded data

byte[] data = Base64.decode(text, Base64.DEFAULT);

String text1 = new String(data, "UTF-8"); //text1 is decoded data

editText.getText().replace(min2, max2, text1);

String fullText = editText.getText().toString();

editText.setText(fullText.replace(text, ""));

}
