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;
}
}
