首先上Main_layout的布局

main_layout的布局
然后Main_Activity的代码

public class MainActivity extends AppCompatActivity {

    private Button button_dial;
    private Button button_smss;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(R.layout.activity_main);
         button_dial = (Button)findViewById(R.id.bt_dial);
        button_smss = (Button)findViewById(R.id.bt_sm);
        button_dial.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent intent  = new Intent(MainActivity.this,Dialing.class);
                startActivity(intent);
            }
        });
        button_smss.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent intent = new Intent(MainActivity.this,SMSS.class);
                startActivity(intent);
            }
        });

    }

}

然后就是dial_layout的截图这是dial_layout的布局
然后该上dialing的代码
`public class Dialing extends Activity {

private Button bt_dial;
private EditText editText_phone;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    setContentView(R.layout.dialing_layout);
    bt_dial = (Button)findViewById(R.id.bt_dialing);
    editText_phone = (EditText)findViewById(R.id.bt_phone);
    bt_dial.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            //获取用户输入的号码
            String et = editText_phone.getText().toString();
            Toast.makeText(Dialing.this,"正在拨号给"+et,Toast.LENGTH_SHORT).show();
            //创建意图
            Intent intent = new Intent();
            //把动作封装到意图当中
            intent.setAction(intent.ACTION_CALL);
            //设置打给谁
            intent.setData(Uri.parse("tel:"+et));
        //拨打电话    startActivity(intent);
        }
    });
}

}
`
短信的layout
这里写图片描述

public class SMS extends Activity {
    private EditText editText_phone;
    private EditText editText_content;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(R.layout.smss_layout);

    }
    public void send(View view){
        editText_content = (EditText) findViewById(R.id.editText_content);
        editText_phone = (EditText) findViewById(R.id.editText_phone);
        //获取收件人信息
        String et_content = editText_content.getText().toString();
        //获取短信内容
        String et_phone = editText_phone.getText().toString();
        //获取短信管理器
        SmsManager sm = SmsManager.getDefault();
        //切割短信，把长短信分成若干条小短信
        ArrayList<String> sms = sm.divideMessage(et_content);
        //发送所有小短信
        for (String string:sms) {
            sm.sendTextMessage(et_phone, null, string, null, null);
        }
    }

}

最后manifests别忘了注册权限<uses-permission android:name="android.permission.CALL_PHONE"></uses-permission> <uses-permission android:name="android.permission.SEND_SMS"></uses-permission>
