ForceClose on .getString？

Question

我试图将字符串从一个活动拉到另一个活动，但是每次我试图打开一个活动时，我都会在.getString上得到一个强制命令。

Logcat错误

调用字符串的活动

public class ThisActivity extends Activity{

private TextView reciever;
private String rec;

@Override
public void onCreate(Bundle savedInstanceState){
    super.onCreate(savedInstanceState);
    setContentView(R.layout.elayout);

    reciever = (TextView) findViewById (R.id.Reciver);
    rec = 
        getIntent()
        .getExtras()
        .getString
        ("send");
    reciever.setText(rec);

}

具有字符串的活动

public class OtherActivity extends Activity{
private EditText sendto;
private Button save;

@Override
public void onCreate(Bundle savedInstanceState){
    super.onCreate(savedInstanceState);
    setContentView(R.layout.emailactivity);

    sendto = (EditText) findViewById(R.id.sendto);
    save = (Button) findViewById(R.id.Save);

    save.setOnClickListener(new OnClickListener(){
        public void onClick(View v){
            Intent intent = new Intent (EmailActivity.this,EmailSettings.class);
            intent.putExtra("send", sendto.getText().toString());
            startActivity(intent);
        }
    });
}
}

谢谢你的帮助。

Answer 1

尝试使用getIntent().getStringExtra("send");

如果您想检查是否有额外费用，请使用：

getIntent().hasExtra("send");

Answer 2

尝试从getString()函数中删除空异常
