我的继承人份额菜单代码（XML）：

<menu xmlns:android="http://schemas.android.com/apk/res/android"> 
<item android:id="@+id/menu_share" 
     android:title="Share"

</menu> 

而且继承人我的java：

package com.example.Encryptor_Kik; 

import android.app.Activity; 
import android.content.Intent; 
import android.os.Bundle;

    super.onCreate(savedInstanceState); 
    setContentView(R.layout.decryption); 
} 
@Override 
public boolean onCreateOptionsMenu(Menu menu) { 
    MenuInflater menuInflater = getMenuInflater(); 
    menuInflater.inflate(R.menu.menu2, menu); 
    MenuItem shareItem = menu.findItem(R.id.menu_share); 

    ShareActionProvider mShare = (ShareActionProvider)shareItem.getActionProvider(); 
    Intent shareIntent = new Intent(Intent.ACTION_SEND); 
    shareIntent.setAction(Intent.ACTION_SEND); 
    shareIntent.setType("text/plain"); 
    shareIntent.putExtra(Intent.EXTRA_TEXT, "Hi"); 
    mShare.setShareIntent(shareIntent); 


    return super.onCreateOptionsMenu(menu); 
} 




}

的问题是，你的代码是在onCreateOptionsMenu和创造它的EditText的时间是空的，所以text是空的。您需要添加一个侦听器来更改文本。这里是全代码 -

public class Decryptor extends Activity { 
EditText e; 
private ShareActionProvider mShare; 
@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.decryption); 
    e=(EditText)findViewById(R.id.YourID); 
    e.addTextChangedListener(commonTextWatcher); 


    TextWatcher commonTextWatcher 
    = new TextWatcher(){ 

    @Override 
    public void afterTextChanged(Editable s) { 
    String text=e.getText.toString(); 
    Intent shareIntent = new Intent(Intent.ACTION_SEND); 
    shareIntent.setAction(Intent.ACTION_SEND); 
    shareIntent.setType("text/plain"); 
    shareIntent.putExtra(Intent.EXTRA_TEXT, text); 
    if (mShare != null) { 
    mShare.setShareIntent(shareIntent); 
    } 
    } 

    @Override 
    public void beforeTextChanged(CharSequence s, int start, int count, 
    int after) { 
    // TODO Auto-generated method stub 

    } 

    @Override 
    public void onTextChanged(CharSequence s, int start, int before, 
    int count) { 
    // TODO Auto-generated method stub 

    }}; 
} 
@Override 
public boolean onCreateOptionsMenu(Menu menu) { 
    MenuInflater menuInflater = getMenuInflater(); 
    menuInflater.inflate(R.menu.menu2, menu); 
    MenuItem shareItem = menu.findItem(R.id.menu_share); 
    String text=e.getText.toString(); 
    mShare = (ShareActionProvider)shareItem.getActionProvider(); 
    Intent shareIntent = new Intent(Intent.ACTION_SEND); 
    shareIntent.setAction(Intent.ACTION_SEND); 
    shareIntent.setType("text/plain"); 
    shareIntent.putExtra(Intent.EXTRA_TEXT, text); 
    mShare.setShareIntent(shareIntent); 


    return super.onCreateOptionsMenu(menu); 
} 
}
