android隐藏以及显示软键盘

1. //隐藏软键盘   

 ((InputMethodManager)getSystemService(INPUT_METHOD_SERVICE)).hideSoftInputFromWindow(WidgetSearchActivity.this.getCurrentFocus().getWindowToken(), InputMethodManager.HIDE_NOT_ALWAYS);   

  

//显示软键盘,控件可以是EditText,TextView   

((InputMethodManager)getSystemService(INPUT_METHOD_SERVICE)).showSoftInput(控件, 0);  

     2.利用时间来控制软键盘的弹出实例：

public class MainActivity extends Activity {

private Context context;

private EditText mEditText;

/** Called when the activity is first created. */
@Override
  public void onCreate(Bundle savedInstanceState) {
                      super.onCreate(savedInstanceState);
  setContentView(R.layout.main);
  context = this;
  mEditText = (EditText) findViewById(R.id.EditText01);
  mEditText.requestFocus();

  Timer timer = new Timer();
  timer.schedule(new TimerTask() {

   @Override
                 public void run() {
               InputMethodManager m = (InputMethodManager) context.getSystemService   (Context.INPUT_METHOD_SERVICE);
              m.toggleSoftInput(0, InputMethodManager.HIDE_NOT_ALWAYS);
       }

                 }, 1000);
       }
}
