Android之鍵盤點擊事件

很簡單，自己儲存著用。就貼出代碼：

package archie.android.activity;import android.app.Activity;import android.os.Bundle;import android.view.KeyEvent;import android.view.MotionEvent;import android.view.View;import android.widget.Button;import android.widget.Toast;public class ActivityEvent extends Activity {private Button ok;    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.main);        ok=(Button) findViewById(R.id.myButton);        ok.setText(R.string.ok);        ok.setOnClickListener(new Button.OnClickListener(){@Overridepublic void onClick(View v) {DisplayToast("點擊了OK按鈕");}});    }    /*鍵按下事件*/    public boolean onKeyDown(int keyCode,KeyEvent event){    switch(keyCode){       case KeyEvent.KEYCODE_DPAD_CENTER:       DisplayToast("按下：中鍵");       break;       case KeyEvent.KEYCODE_DPAD_UP:       DisplayToast("按下：上方向鍵");       break;       case KeyEvent.KEYCODE_DPAD_DOWN:       DisplayToast("按下：下方向鍵");       break;       case KeyEvent.KEYCODE_DPAD_LEFT:       DisplayToast("按下：左方向鍵");       break;       case KeyEvent.KEYCODE_DPAD_RIGHT:       DisplayToast("按下：右方向鍵");       break;    }return super.onKeyDown(keyCode, event);    }    /*釋放按鍵事件*/    public boolean onKeyUp(int keyCode,KeyEvent event){    switch(keyCode){    case KeyEvent.KEYCODE_DPAD_CENTER:    DisplayToast("釋放：中鍵");    break;    case KeyEvent.KEYCODE_DPAD_UP:    DisplayToast("釋放：上方向鍵");    break;    case KeyEvent.KEYCODE_DPAD_DOWN:    DisplayToast("釋放：下方向鍵");    break;    case KeyEvent.KEYCODE_DPAD_LEFT:    DisplayToast("釋放：左方向鍵");    break;    case KeyEvent.KEYCODE_DPAD_RIGHT:    DisplayToast("釋放：右方向鍵");    break;   }return super.onKeyUp(keyCode, event);    }    /*連擊事件*/    public boolean onKeyMultiple(int keyCode,int repeatCount,KeyEvent event){    return super.onKeyMultiple(keyCode, repeatCount, event);    }    /*觸筆事件*/    public boolean onTouchEvent(MotionEvent event){    int iAction=event.getAction();    if(iAction==MotionEvent.ACTION_CANCEL||iAction==MotionEvent.ACTION_DOWN||iAction==MotionEvent.ACTION_MOVE){    return false;    }    //    int x=(int)event.getX();    int y=(int) event.getY();    DisplayToast("觸筆點擊座標:("+Integer.toString(x)+","+Integer.toString(y)+")");return super.onTouchEvent(event);    }private void DisplayToast(String str) {Toast.makeText(this, str, Toast.LENGTH_SHORT).show();}}
