输入法

当我们弹出一个Dialog时候，如果这个Dialog需要输入数据，然后确定后又需要关闭输入法，一般系统的hide，跟show方法总会有各种问题，最霸道的解决方法就是写一个定时器，定时弹出或者关闭输入法。

import java.util.Timer;import java.util.TimerTask;import android.content.Context;import android.view.View;import android.view.inputmethod.InputMethodManager;import android.widget.EditText;public class InputTools {    //隐藏虚拟键盘      public static void HideKeyboard(View v)      {          InputMethodManager imm = ( InputMethodManager ) v.getContext( ).getSystemService( Context.INPUT_METHOD_SERVICE );             if ( imm.isActive( ) ) {                 imm.hideSoftInputFromWindow( v.getApplicationWindowToken( ) , 0 );                       }          }            //显示虚拟键盘      public static void ShowKeyboard(View v)      {          InputMethodManager imm = ( InputMethodManager ) v.getContext( ).getSystemService( Context.INPUT_METHOD_SERVICE );                     imm.showSoftInput(v,InputMethodManager.SHOW_FORCED);              }            //强制显示或者关闭系统键盘      public static void KeyBoard(final EditText txtSearchKey,final String status)      {                     Timer timer = new Timer();        timer.schedule(new TimerTask(){        @Override        public void run()        {            InputMethodManager m = (InputMethodManager)            txtSearchKey.getContext().getSystemService(Context.INPUT_METHOD_SERVICE);             if(status.equals("open"))             {                 m.showSoftInput(txtSearchKey,InputMethodManager.SHOW_FORCED);              }             else             {                 m.hideSoftInputFromWindow(txtSearchKey.getWindowToken(), 0);              }         }           }, 300);       }            //通过定时器强制隐藏虚拟键盘      public static void TimerHideKeyboard(final View v)      {          Timer timer = new Timer();        timer.schedule(new TimerTask(){        @Override        public void run()        {            InputMethodManager imm = ( InputMethodManager ) v.getContext( ).getSystemService( Context.INPUT_METHOD_SERVICE );                 if ( imm.isActive( ) )            {                     imm.hideSoftInputFromWindow( v.getApplicationWindowToken( ) , 0 );            }             }          }, 10);       }      //输入法是否显示着      public static boolean KeyBoard(EditText edittext)      {          boolean bool = false;          InputMethodManager imm = ( InputMethodManager ) edittext.getContext( ).getSystemService( Context.INPUT_METHOD_SERVICE );             if ( imm.isActive( ) )        {                bool = true;         }            return bool;                }}
