如何在Android中单击按钮时停止发送正在循环发送的消息

Question

I want to know how can I stop message sending in a loop.
When I press stop, messages are still sent.
I have provided a stop() method.

for (i = 0; i < copy; i++) {
                new Handler().postDelayed(new Runnable() {

                    @Override
                    public void run() {
                        if(stop!=1)
                            sms.sendTextMessage(number,null,message,sentPIn,pdelint);
                    }

                }, 25000);


stop method

int stop=0;

public void st(View view){
    Button b=(Button)findViewById(R.id.button2);
    b.setText("Stopped");
    stop=1;
}

Answer 1

Modify St function to this

public void st() {
     Button b = (Button) findViewById(R.id.button);
     @Override
     b.setOnClickListener(new View.OnClickListener() {
           b.setText("Stopped!");
           stop=1;
     });
}

The problem was u were not using an listener to detect button press. It is not advisable to change the button text use a text view instead!

Answer 2

Most likely he has set onClick attribute in the xml, although only he'll be able to clarify that.

I'm saying that because I see View as a parameter in the method st(View v) .

Although if the attribute onClick is not set in xml @Audi 's solution would be good. Though on the contrary if the attribute has been set in the xml then you should check if view.getId() == R.id.button then apply a button cast to your view and set its text to "Stopped".
