@Override
    public boolean onKeyDown(int keyCode, KeyEvent event)
    {
        if(keyCode == KeyEvent.KEYCODE_BACK){
            //要在這里跳轉啊
            Intent intent = new Intent();
            intent = new Intent(ActivityA.this, ActivityB.class);
            startActivity(intent);
            this.finish();
        }
        return super.onKeyDown(keyCode, event);
    }

但是我監聽返回鍵是返回webview里面瀏覽的上個頁面?。?/p>

在界面中加個按鈕實現界面跳轉，或者在這個Activity中監聽返回按鍵

@Override 
　　public boolean onKeyDown(int keyCode, KeyEvent event) {         
　　//按下鍵盤上返回按鈕
　　if(keyCode == KeyEvent.KEYCODE_BACK){
　　    return true;
　　}　　
　　return super.onKeyDown(keyCode, event);
}
