[color=violet]哈哈，在蘋果手機上玩過類似游戲，在eoe上發現一個兄弟也模仿做了一個，今天趁周末自己也做了一個，借用了那位兄弟的一些美女圖片，應該不涉及版權吧。程序有點yellow，希望iteye管理員高臺貴手 :cry: ，本意是給大家帶來點樂趣。

為保護你的隱私，設置了密碼保護。[/color]
下面貼部分關鍵代碼：
@Override
public void onClick(View v) {
int id = v.getId();
switch (id) {
case R.id.yesBtn: {
SharedPreferences preferences = getSharedPreferences("password",Activity.MODE_PRIVATE);
String pwd = preferences.getString("pwd", "");
if(pwd!=null&&!"".equals(pwd)){
if(password.getText().toString()!=""&&password.getText()!=null&&password.getText().toString().equals(pwd)){
//Toast.makeText(PasswordActivity.this, "密碼一致，請重新輸入密碼", Toast.LENGTH_SHORT).show();
Intent intent = new Intent();
intent.setClass(PasswordActivity.this, SettingsActivity.class);
startActivity(intent);
PasswordActivity.this.finish();
}else{
Toast.makeText(PasswordActivity.this, "密碼不一致，請重新輸入密碼", Toast.LENGTH_SHORT).show();
}
}else{
SharedPreferences ferences = getSharedPreferences("password",Activity.MODE_PRIVATE);
SharedPreferences.Editor editor = ferences.edit();
editor.putString("pwd", password.getText().toString());
editor.commit();
//Toast.makeText(PasswordActivity.this, "已經設置密碼", Toast.LENGTH_SHORT).show();
Intent intent = new Intent();
intent.setClass(PasswordActivity.this, SettingsActivity.class);
startActivity(intent);
PasswordActivity.this.finish();
}


}
break;
case R.id.cancelBtn: {
PasswordActivity.this.finish();
}
break;
}
}

[color=red]下面是下面這張圖片所顯示的界面的實現,底部是一個gallery，顯示大圖用的是ImageSwither這個組件，一點要注意的地方是要實現ViewFactory接口并實現方法makeView();[/color]
