当我使用Toast在屏幕上显示一些弹出文本时,它会将文本显示在屏幕底部上方一点的位置,这是默认位置。

现在我想把它显示在屏幕中间,或者根据我的选择显示在某个地方。

有人能指导我如何实现这个目标吗?

Toast toast = Toast.makeText(this, "Custom toast creation", Toast.LENGTH_SHORT);
    toast.setGravity(Gravity.BOTTOM | Gravity.RIGHT,0,0);
    toast.show();

解决方案

fun Context.showToastOnTOP(message: String) = Toast.makeText(this, message, Toast.LENGTH_SHORT)
    .apply { setGravity(Gravity.TOP, 0, 0); show() }

fun Context.showToastOnBOTTOM(message: String) = Toast.makeText(this, message, Toast.LENGTH_SHORT)
    .apply { setGravity(Gravity.BOTTOM, 0, 0); show() }

重要提示:重力只有在应用程序的最大目标为29或更少时才能工作。

从文档来看,

Positioning your Toast A standard toast notification appears near the bottom of the screen, centered horizontally. You can change this position with the setGravity(int, int, int) method. This accepts three parameters: a Gravity constant, an x-position offset, and a y-position offset. For example, if you decide that the toast should appear in the top-left corner, you can set the gravity like this: toast.setGravity(Gravity.TOP|Gravity.LEFT, 0, 0); If you want to nudge the position to the right, increase the value of the second parameter. To nudge it down, increase the value of the last parameter.

Toast toast = Toast.makeText(this, "Custom toast creation", Toast.LENGTH_SHORT);
    toast.setGravity(Gravity.BOTTOM | Gravity.RIGHT,0,0);
    toast.show();

如果你得到一个指示你必须调用makeText的错误,下面的代码将修复它:

Toast toast= Toast.makeText(getApplicationContext(), 
"Your string here", Toast.LENGTH_SHORT);  
toast.setGravity(Gravity.TOP|Gravity.CENTER_HORIZONTAL, 0, 0);
toast.show();
Toast mytoast= Toast.makeText(getApplicationContext(), "Toast Message", 1);  
mytoast.setGravity(Gravity.CENTER_HORIZONTAL, 0, 0);  // for center horizontal
//mytoast.setGravity(Gravity.CENTER_VERTICAL);       // for center vertical 
//mytoast.setGravity(Gravity.TOP);                       // for top
mytoast.show();

上面的代码将帮助你在屏幕中间显示吐司,或者根据你的选择,根据你的需要设置吐司的重力

注意:对于这个过程,你必须使用object of Toast
