Question

我在android活动中创建了2个按钮，这些按钮与不同的类相关联，每个类有4到5个按钮，每个按钮都被编码用于向特定的人发送消息。但是当我在我的设备上运行它时，应用程序崩溃了。

这是我的代码：

callButton.setOnClickListener(new OnClickListener(){
    @Override
    public void onClick(View v) {
        Intent i = new Intent(Intent.ACTION_DIAL, Uri.parse("tel:" + telephone-number));
        startActivity(i);
    }
});

有人能告诉我应用程序崩溃的原因吗？

protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.second);

        Button z = (Button) findViewById(R.id.button1);
        z.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View l) {
                // TODO Auto-generated method stub
                String messageToSend = "Come Out Bro....";
                 String fnumber = "03339579504";    
                 SmsManager.getDefault().sendTextMessage(fnumber, null, messageToSend, null,null);


            }
        });

        Button x = (Button) findViewById(R.id.button2);
        x.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View y) {
                // TODO Auto-generated method stub
                String messageSend = "Come Out Bro....";
                 String snumber = "03339023418";    
                 SmsManager.getDefault().sendTextMessage(snumber, null, messageSend, null,null);

            }
        });


        Button c = (Button) findViewById(R.id.butt4);
    c.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View u) {
            // TODO Auto-generated method stub
            String ToSend = "Come Out Bro....";
             String anumber = "03443444720";    
             SmsManager.getDefault().sendTextMessage(anumber, null, ToSend, null,null);



        }
    });

    Button v = (Button) findViewById(R.id.butt5);
    v.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View i) {
            // TODO Auto-generated method stub

            String kmessageToSend = "Come Out Bro....";
             String knumber = "03139644916";    
             SmsManager.getDefault().sendTextMessage(knumber, null, kmessageToSend, null,null);     

        }

    });

    Button b = (Button) findViewById(R.id.butt6);
    b.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View o) {
            // TODO Auto-generated method stub
            String almessageToSend = "Come Out Bro....";
             String alnumber = "03451923255";   
             SmsManager.getDefault().sendTextMessage(alnumber, null, almessageToSend, null,null);       



        }
    });

    Button n = (Button) findViewById(R.id.butt3);
    n.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View p) {
            // TODO Auto-generated method stub
            String zamessageToSend = "Come Out Bro....";
             String zanumber = "03015932300";   
             SmsManager.getDefault().sendTextMessage(zanumber, null, zamessageToSend, null,null);       



        }
    });
    }




}

Answer 1

您是否在Manifest中添加了权限？

添加此项以拨打电话并发送消息 -

<uses-permission android:name="android.permission.CALL_PHONE" />
<uses-permission android:name="android.permission.SEND_SMS"/>

如果您有更多按钮执行此类操作，则必须先在Manifest中添加权限。

很多按钮，很多问题（崩溃）
