如何将Toast的动态位置设置为视图？ [英] How to set Dynamic position of Toast to a View?

问题描述

首先这不是完整的代码

@Override
    public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) 
    {
        Toast toast=Toast.makeText(getApplicationContext(), "", Toast.LENGTH_SHORT);
        toast.setGravity(Gravity.CENTER_HORIZONTAL, 0, 0); 
        View view=toast.getView();
        switch(buttonView.getId())
        {
            case R.id.chkRed: if(chkRed.isChecked())
            {   
                              chkGreen.setChecked(false);
                              chkBlue.setChecked(false);
                              chkYellow.setChecked(false);
                              toast.setText("You Selected Red");
                                toast.setGravity(Gravity.NO_GRAVITY,buttonView.getRight(), chkRed.getTop());
                             //top does not align
                             //it align perfectly to right of checkbox
                              view.setBackgroundColor(Color.RED);
            }
                             break;
}
}

所以现在的问题是我想展示吐司在复选框旁边，我尝试使用 setGravity（），但是它没有工作，已经被击中并尝试了很长时间，但是没有任何进展

So now the problem is that I want to display toast beside checkbox, I tried working with setGravity(), but it just does not workup and have been hit and trying for long time, but with no progress

推荐答案

好的，我终于想出了如何在复选框或其他视图旁边举杯祝酒

ok, i finally figured out how to get toast beside checkbox or another view

1。。您需要在视图屏幕上找到位置，方法是

1. You need to get location on screen of the view, by

buttonView.getLocationOnScreen(location);

有关更多参考，请参见 getLocationOnScreen（int []）

for more Reference, see getLocationOnScreen(int[])

2。。使用

toast.setGravity(Gravity.TOP|Gravity.LEFT,buttonView.getRight()+5, 
location[1]-10);

这里重要的是设置 x坐标烤面包到视图的右侧，
，例如 buttonView.getRight（），并从位置[1]获取y坐标，您可以从 getLocationOnScreen（）

the important thing here is set x-coordinate of toast to right of view, e.g., buttonView.getRight() and get y-coordinate from the location[1] ,which you get from getLocationOnScreen()

public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) 
    {
        Toast toast=Toast.makeText(getApplicationContext(), "", Toast.LENGTH_SHORT);
        toast.setGravity(Gravity.TOP|Gravity.LEFT, 0, 0); 
        View view=toast.getView();
        int location[]=new int[2];
        buttonView.getLocationOnScreen(location);
        switch(buttonView.getId())
        {
            case R.id.chkRed: if(chkRed.isChecked())
            {   
                              chkGreen.setChecked(false);
                              chkBlue.setChecked(false);
                              chkYellow.setChecked(false);
                              toast.setText("You Selected Red");
                              toast.setGravity(Gravity.TOP|Gravity.LEFT,buttonView.getRight()+5, location[1]-10);
                              view.setPadding(1, 1, 1, 1);
                              view.setBackgroundColor(Color.RED);
            }

        }
    }
