android - 停止广播接收器时出现问题

Question

我正在做一个会说出来电者姓名的应用程序。它有一个主活动和两个广播接收器，用于监控来电和短信。从该接收器开始，它会启动一项服务，以说出呼叫者的姓名。

我面临的问题是

  I want to start ans stop this broadcast receivers from the UI.i mean with the help of two buttons.

有可能吗，如果可以，我该怎么做？

Answer 1

Sure. When you want to start it, call registerReceiver. When you want it off, call unregisterReceiver.

Answer 2

在按钮单击注册接收器：

YourReceiver mReceiver ;
btnRegister.setOnClickListener(new OnClickListener() {
                @Override
                public void onClick(View v) {
                                  IntentFilter filter = new IntentFilter(your action filter);
                     mReceiver = new YourReceiver();
                                 registerReceiver(mReceiver, filter);
    }
});

未注册的接收者：

 btnRegister.setOnClickListener(new OnClickListener() {
                @Override
                public void onClick(View v) {
try
        {

            unregisterReceiver(mReceiver);
        }catch(IllegalArgumentException ex)
        {
            //your message.
        }
    }
});

希望这可以帮助...
