我对我的朋友提供的使用 GUI 处理程序来替代保存共享首选项的 StaticClass 代码感到困惑
我的代码中有以下代码selectlevel.class
public class selectlevel extends Activity {
Button f1, f2, f3;
ImageView f2lock, f3lock;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.selectlevel);
f1 =(Button)findViewById(R.id.f1);
f1.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v){
// TODO Auto-generated method stub
Intent level1 = new Intent ();
level1.setClassName ("com.example.game", "com.example.game.levelone");
startActivity (level1);
}
});
}
f2=(Button)findViewById(R.id.f2);
f2lock=(ImageView)findViewById(R.id.f2lock);
f2.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v){
// TODO Auto-generated method stub
Intent level2 = new Intent ();
level2.setClassName ("com.example.game", "com.example.game.leveltwo");
startActivity (level2);
}
});
}
}
所以我的朋友用 GUI Handler 提供 StaticClass 代码，以便在最新级别时使按钮可见finish();并保存
这是以下代码
static class PlayerProgress {
// We set progress to static, so it would be alive, no matter what activity you're in.
private static int progress = 1;
/**
* Update the player's progress.
* @param levelNumber: latest level number.
*/
public static void updateProgress(int levelNumber) {
progress = levelNumber;
}
/**
* Get the player's progress.
* @return the latest level number.
*/
public static int getPlayerProgress() {
return progress;
}
}
/**
* The gui handler would need to be called, every time you need to update the screen to the
* appropriate level and it's assets. (Buttons, activities ect.)
*
* I would implement a MainActivity, which would handle the different screens.
*
*/
class guiHandler {
public void updateLevel() {
int progress = PlayerProgress.getPlayerProgress();
/*
* Add your
*/
switch(progress) {
case 1:
f2.setVisibility(View.VISIBLE);
f2lock.setVisibility(View.GONE);
break;
case 2:
f3.setVisibility(View.VISIBLE);
f3lock.setVisibility(View.GONE);
break;
// You can expand this to as many levels you'd like.
}
}
}
我只是很困惑如何将我的代码和我朋友提供的 StaticClass 代码结合起来以在最新级别完成时保存按钮可见性
谁能帮我写代码？
更新
我对我的代码进行了这样的更改
f1=(Button)findViewById(R.id.f1);
f1.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v){
// TODO Auto-generated method stub
Intent level1 = new Intent ();
level1.setClassName ("com.example.game", "com.example.game.levelone");
startActivity (level1);
}
});
f2=(Button)findViewById(R.id.f2);
f2lock=(ImageView)findViewById(R.id.f2lock);
f2.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v){
// TODO Auto-generated method stub
Intent level2 = new Intent ();
level2.setClassName ("com.example.game", "com.example.game.leveltwo");
startActivity (level2);
}
});
updateLevels();
}
static class PlayerProgress {
private static int progress = 0;
public static void updateProgress(int levelNumber) {
progress = levelNumber;
}
public static int getPlayerProgress() {
return progress;
}
}
public void updateLevels() {
int progress = PlayerProgress.getPlayerProgress();
switch(progress) {
case 1:
f2.setVisibility(View.VISIBLE);
f2lock.setVisibility(View.GONE);
break;
case 2:
break;
// You can expand this to as many levels you'd like.
}
}
并在我的levelone.class
button1.setOnClickListener(new View.OnClickListener() {
public void onClick(View v){
selectlevel.PlayerProgress.updateProgress(1);
finish();
当levelone.class 完成 f2 按钮仍然消失时，如何解决这个问题？
