如果顯示則隱藏 否則彈出彈窗

if (isSoftShowing()) {
    final View v = (this).getWindow().peekDecorView();
    if (v != null && v.getWindowToken() != null) {
        InputMethodManager imm = (InputMethodManager) getSystemService(INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(v.getWindowToken(), 0);
}
} else 
 
{
    CardPopuUtil.getInstance().showPopu(tvMeBackcardCardtype, tvMeBackcardCardtype, this);
}

判斷是否顯示方法

private boolean isSoftShowing() {

    //獲取當螢幕內容的高度
int screenHeight = this.getWindow().getDecorView().getHeight();
//獲取View可見區域的bottom
Rect rect = new Rect();
//DecorView即為activity的頂級view
this.getWindow().getDecorView().getWindowVisibleDisplayFrame(rect);
 
//考慮到虛擬導航欄的情況（虛擬導航欄情況下：screenHeight = rect.bottom + 虛擬導航欄高度）
    //選取screenHeight*2/3進行判斷
return screenHeight*2/3 > rect.bottom;
}
