Question

您好我正在尝试开发和应用程序，需要从一个编辑文本框发送文本到另一个应用程序，如Kik，我已经做了共享菜单，我只需要让它从我的编辑文本框发送文本

继承我的共享菜单代码（XML）：

<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="@+id/menu_share"
      android:title="Share"
      android:orderInCategory="100"
      android:showAsAction="ifRoom"
      android:actionProviderClass= "android.widget.ShareActionProvider" />

</menu>

继承我的java：

package com.example.Encryptor_Kik;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.MenuItem;
import android.widget.ShareActionProvider;

public class Decryptor extends Activity {

@Override
public void onCreate(Bundle savedInstanceState) {
    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);
}




}

问题是您的代码位于onCreateOptionsMenu，在创建代码时，EditText为空，因此text为空。您需要添加一个用于更改文本的侦听器。这是完整的代码 -

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);
}
}

如何将文本从编辑文本框发送到另一个应用程序？
