Android软键盘工具类
public class SoftKeyboardUtils {/*** 隐藏或显示软键盘* 如果现在是显示调用后则隐藏 反之则显示*/public static void showORhideSoftKeyboard(Activity activity) {InputMethodManager imm = (InputMethodManager) activity.getSystemService(Context.INPUT_METHOD_SERVICE);imm.toggleSoftInput(0, InputMethodManager.HIDE_NOT_ALWAYS);}// 显示软键盘private fun showKeyboard(editText: EditText) {//调用系统输入法editText.postDelayed({val inputManager: InputMethodManager =context.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManagerinputManager.showSoftInput(editText, 0)// SoftKeyboardUtils.showSoftKeyboard(this)}, 60)}// 隐藏软键盘private fun hideShowKeyboard(editText: EditText) {val manager = context.getSystemService(INPUT_METHOD_SERVICE) as InputMethodManagermanager.hideSoftInputFromWindow(editText.windowToken, 0)}/*** 判断软键盘是否显示方法*/public static boolean isSoftShowing(Activity activity) {//获取当屏幕内容的高度int screenHeight = activity.getWindow().getDecorView().getHeight();//获取View可见区域的bottomRect rect = new Rect();//DecorView即为activity的顶级viewactivity.getWindow().getDecorView().getWindowVisibleDisplayFrame(rect);//考虑到虚拟导航栏的情况（虚拟导航栏情况下：screenHeight = rect.bottom + 虚拟导航栏高度）//选取screenHeight*2/3进行判断boolean isOpen = screenHeight * 2 / 3 > rect.bottom + getSoftButtonsBarHeight(activity);LegoLog.d("键盘是否显示：" + isOpen);return isOpen;}/*** 底部虚拟按键栏的高度*/@TargetApi(Build.VERSION_CODES.JELLY_BEAN_MR1)private static int getSoftButtonsBarHeight(Activity activity) {DisplayMetrics metrics = new DisplayMetrics();//这个方法获取可能不是真实屏幕的高度activity.getWindowManager().getDefaultDisplay().getMetrics(metrics);int usableHeight = metrics.heightPixels;//获取当前屏幕的真实高度activity.getWindowManager().getDefaultDisplay().getRealMetrics(metrics);int realHeight = metrics.heightPixels;if (realHeight > usableHeight) {return realHeight - usableHeight;} else {return 0;}}}
注意，在Dialogdismiss之前调用该方法。（先关闭软键盘，再关闭弹窗）
