Android強制彈出，隱藏輸入法.

當我們彈出一個Dialog時候，如果這個Dialog需要輸入數據，然后確定后又需要關閉輸入法，一般系統的hide，跟show方法總會有各種問題，最霸道的解決方法就是寫一個定時器，定時彈出或者關閉輸入法。

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 {

    //隱藏虛擬鍵盤
      public static void HideKeyboard(View v)
      {
          InputMethodManager imm = ( InputMethodManager ) v.getContext( ).getSystemService( Context.INPUT_METHOD_SERVICE );     
        if ( imm.isActive( ) ) {     
            imm.hideSoftInputFromWindow( v.getApplicationWindowToken( ) , 0 );   
            
        }    
      }
      
      //顯示虛擬鍵盤
      public static void ShowKeyboard(View v)
      {
          InputMethodManager imm = ( InputMethodManager ) v.getContext( ).getSystemService( Context.INPUT_METHOD_SERVICE );     
        
        imm.showSoftInput(v,InputMethodManager.SHOW_FORCED);    
    
      }
      
      //強制顯示或者關閉系統鍵盤
      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);
       }
      
      //通過定時器強制隱藏虛擬鍵盤
      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);
       }
      //輸入法是否顯示着
      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;
          
      }
}
