发短信和打电话

我们做一个这样的界面

 

 

1、点击按钮，可以唤起 打电话 、发短信的界面

2、长按按钮，直接拨号和发送短信

我们通过在界面上绑定点击监听

            <Button
                android:id="@+id/btn_call"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="拨打电话"
                android:onClick="jumpCall"/>
            <Button
                android:id="@+id/btn_sms"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="发送短信"
                android:onClick="jumpSendMessage"/>

 

通过实现 OnLongClickListener接口，绑定长按监听

 

 然后进行绑定

btn_call.setOnLongClickListener(this);
btn_sms.setOnLongClickListener(this);

 

然后实现方法即可。这里要注意的是，Android 6.0 之后，在申明权限外，还要动态申请权限

if (checkSelfPermission(permission.SEND_SMS) != PackageManager.PERMISSION_GRANTED) {
    // TODO: Consider calling
    //    Activity#requestPermissions
    // here to request the missing permissions, and then overriding
    //   public void onRequestPermissionsResult(int requestCode, String[] permissions,
    //                                          int[] grantResults)
    // to handle the case where the user grants the permission. See the documentation
    // for Activity#requestPermissions for more details.
    ActivityCompat.requestPermissions(this, new String[]{permission.SEND_SMS}, 1);
    //ActivityCompat.shouldShowRequestPermissionRationale(this, permission.CALL_PHONE);
    return;
}
