问题 I have read about this kind of problem here but the answers don\'t seem to be working. I show a Toast when user clicks a button. When the user continously clicks the button the toast keeps on being displayed again and again even when the user exits the activity. The length of the toast is short. Length of the toast cannot be changed as the text is long. This is what i have tried as of now: Toast toast; toast=Toast.makeText(getApplicationContext(),\"text\",Toast.LENGTH_SHORT); if(toast.getView

I have a slider that can be pulled up and then it shows a map. I can move the slider up and down to hide or show the map. When the map is on front, I can handle touch events on that map. Everytime I touch, a AsyncTask is fired up, it downloads some data and makes a Toast that displays the data. Although I start the task on touch event no toast is displayed, not till I close the slider. When the slider is closed and the map is not displayed anymore the Toast appears. Any ideas? Well start the task EDIT: public boolean onTouchEvent(MotionEvent event, MapView mapView){ if (event.getAction() == 1)

问题 When I use Toast to display some popup text on the screen, it displays the text a little bit above the bottom of the screen, which is the default position. Now I want to display it in the middle of screen or somewhere according to my choice. Can anyone guide me how to achieve this? 回答1: From the documentation, Positioning your Toast A standard toast notification appears near the bottom of the screen, centered horizontally.

1.类的构造 1.1类的简单定义 //java public class MainActivity extends AppCompatActivity { ... } //Kotlin class MainActivity : AppCompatActivity() { ... } Kotlin对类的写法有以下特点： <1>省略了关键字public，缘于它默认就是开放的； <2>用冒号“:”代替extends，表示继承关系； <3>进行继承时，父类后面多了括号() class Animal { //类的初始化函数init init { //Kotlin使用println代替Java的System.out.println println("Animal：这是个动物类") } } var animal = Animal()//类的实例创建，忽略new关键字 1.2 类的构造函数 //如果主构函数没有带@符号的注解说明，constructor就可以省略 //class AnimalMain (context:Context, name:String) { class AnimalMain constructor(context:Context, name:String) { init { context.toast("这是只$name") } } //含二级构造函数 class
