android隱藏以及顯示軟鍵盤

//隱藏軟鍵盤     ((InputMethodManager)getSystemService(INPUT_METHOD_SERVICE)).hideSoftInputFromWindow(WidgetSearchActivity.this.getCurrentFocus().getWindowToken(), InputMethodManager.HIDE_NOT_ALWAYS);       //顯示軟鍵盤,控制項可以是EditText,TextView    ((InputMethodManager)getSystemService(INPUT_METHOD_SERVICE)).showSoftInput(控制項, 0);

     2.利用時間來控制軟鍵盤的彈出執行個體：

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);
       }
}
