不确定这是否有效，但我正尝试从CustomerCall活动向Toledo活动发送Toast消息。android - 将烤面包从一项活动传递给另一项活动

一旦司机选择取消。敬酒需要发送到RiderHome活动，说“司机取消了请求”

这可以做到吗？

CustomerCall

btnCancel = (Button)findViewById(R.id.btnDecline); 
    btnCancel.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 
       cancelBooking(); 
     } 
    }); 
} 
private void cancelBooking() { 
    Intent intent = new Intent(getBaseContext(), RiderHome.class); 
    String cancel = "cancel" 
    intent.putExtra("cancel", cancel); 
    startActivity(intent); 
    Toast.makeText(CustomerCall.this, "The Driver has cancelled 
    the request", Toast.LENGTH_LONG).show(); 
}

RiderHome

public class RiderHome extends AppCompatActivity 
    implements NavigationView.OnNavigationItemSelectedListener, OnMapReadyCallback, 
    GoogleApiClient.ConnectionCallbacks, 
    GoogleApiClient.OnConnectionFailedListener, 
    LocationListener { 
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_home); 
    } 
}

你可以做到这一点way-：

private void cancelBooking() { 
    Intent intent = new Intent(getBaseContext(), RiderHome.class); 
    String cancel = "cancel" 
    intent.putExtra("user_cancelled",cancel); 
    startActivity(intent); 
    Toast.makeText(CustomerCall.this, "The Driver has cancelled 
    the request", Toast.LENGTH_LONG).show(); 
}

在此传递一个字符串值，指示驾驶员取消请求

和RiderHome活动，你可以，如果你检查正在通过以下方式获取该值：

Intent intent=getIntent(); 
intent.getExtras(); 
if(intent.hasExtra("user_cancelled")) 
{ 
    You can print your toast here. 
}

，而不是（烤面包与活动 - 吐司的生命是死的，当活动结束）

Toast.makeText(CustomerCall.this, "The Driver has cancelled 
the request", Toast.LENGTH_LONG).show();

到（使用背景！它会生存）

Toast.makeText(getBaseContext(), "The Driver has cancelled 
the request", Toast.LENGTH_LONG).show();
