这就是错误： PendingIntent类型中的方法getBroadcast(Context, int, Intent, int)不适用于参数（new View.OnClickListener(){}, int, Intent, int）错误

这是MainActivity.java的代码：

    import android.app.Activity;
    import android.os.Bundle;
    import android.provider.Telephony.Sms;
    import android.telephony.SmsManager;
    import android.view.View;

    import android.widget.EditText;
    import android.widget.Toast;

    import android.content.BroadcastReceiver;
    import android.content.Context;
    import android.content.Intent;
    import android.content.IntentFilter;
    public class MainActivity extends Activity

    {
    Button btnSendSMS;
    EditText txtPhoneNo;
    EditText txtMessage;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) 
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);        

        btnSendSMS = (Button) findViewById(R.id.btnSendSMS);
        txtPhoneNo = (EditText) findViewById(R.id.txtPhoneNo);
        txtMessage = (EditText) findViewById(R.id.txtMessage);

        btnSendSMS.setOnClickListener(new View.OnClickListener() 
        {
            public void onClick(View v) 
            {                
                String phoneNo = txtPhoneNo.getText().toString();
                String message = txtMessage.getText().toString();

            registerReceiver(new BroadcastReceiver() {
                @Override
                public void onReceive(Context arg0, Intent arg1) {
                    switch (getResultCode()) {
                        case Activity.RESULT_OK:
                            Toast.makeText(getBaseContext(), "SMS delivered", Toast.LENGTH_SHORT).show();
                            break;
                        case Activity.RESULT_CANCELED:
                            Toast.makeText(getBaseContext(), "SMS not delivered", Toast.LENGTH_SHORT).show();
                            break;
                    }
                }
            }, new IntentFilter(DELIVERED));

            SmsManager sms = SmsManager.getDefault();
            sms.sendTextMessage(phoneNo, null, message, sentPI, deliveredPI);
        }

    });
}

}

我正在尝试发送预定的自动短信发送，但我不会对此错误做多少。 PLEAS帮助。

如错误所示，您传入的上下文存在问题。用getApplicationContext（）

替换它 
    PendingIntent sentPI = PendingIntent.getBroadcast(getApplicationContext(), 0, new Intent(SENT), 0);

    PendingIntent deliveredPI = PendingIntent.getBroadcast(getApplicationContext(), 0, new Intent(DELIVERED), 0);

只需更换这两行！

更新：

我只是尝试了它并且它有效！

两条线的问题都是一样的。方法getBroadcast()期待一个上下文作为它的第一个参数。当您调用此方法时，您位于匿名内部类中，在本例中为onClickListener类。当您提供this关键字作为第一个参数时，this引用该onClickListener类。您需要的是获取当前所在应用程序的上下文并将其提供给该方法。您可以通过更改导致此类行的错误来实现此目的。

PendingIntent sentPI = PendingIntent.getBroadcast(MainActivity.getApplication(), 0, new Intent(SENT), 0);
PendingIntent deliveredPI = PendingIntent.getBroadcast(MainAcitivty.getApplication(), 0, new Intent(DELIVERED), 0);

将this替换为MainActivity.getApplication()。
