我目前制作的游戏扩展了此处的教程： http://www.edu4java.com/en/androidgame/androidgame.html
我目前的屏幕布局如下所示： http://postimg.org/image/ghib8fb87/
如您所见，方向键盘和难度单选按钮不在我的自定义视图中。
编辑：尝试使用SharedPreferences：
在我的MainActivity中，我有RadioButtons和Directional键盘的onClick功能（尚未创建）：
import java.text.DecimalFormat;
import java.util.Timer;
import java.util.TimerTask;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.Window;
import android.widget.TextView;
public class MainActivity extends Activity {
/** Called when the activity is first created. */
private AppPreferences _appPrefs;
int hour = 0;
int minute = 0;
int second = 0;
TextView TimeAliveCounter;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.activity_main);
timer();
}
public void runEasy(View view){
_appPrefs.saveSmsBody("1");
}
public void runMedium(View view){
_appPrefs.saveSmsBody("2");
}
public void runHard(View view){
_appPrefs.saveSmsBody("3");
}
private void timer() {
int locMilSec = 0;
int locSec = 0;
int locMin = 0;
int locHr = 0;
DecimalFormat format = new DecimalFormat("00");
String formatMilliSecond = format.format(locMilSec);
String formatSecond = format.format(locSec);
String formatMinute = format.format(locMin);
String formatHour = format.format(locHr);
millisecond = Integer.parseInt(formatMilliSecond);
second = Integer.parseInt(formatSecond);
minute = Integer.parseInt(formatMinute);
hour = Integer.parseInt(formatHour);
Timer T = new Timer();
TimeAliveCounter = (TextView) findViewById(R.id.TimeAlive);
T.scheduleAtFixedRate(new TimerTask() {
@Override
public void run() {
runOnUiThread(new Runnable() {
@Override
public void run() {
TimeAliveCounter.setText(hour + ":"+ minute + ":"+ second + ":" + millisecond);
second++;
if(second > 59){
second = 0;
minute = minute + 1;
}
}
});
}
}, 1000, 1000);
}
}
我的AppPreferences类：
import android.app.Activity;
import android.content.Context;
import android.content.SharedPreferences;
import android.content.SharedPreferences.Editor;
public class AppPreferences {
public static final String KEY_DIFFICULTY = "difficulty";
private static final String APP_SHARED_PREFS = AppPreferences.class.getSimpleName();
private SharedPreferences _sharedPrefs;
private Editor _prefsEditor;
public AppPreferences(Context context) {
this._sharedPrefs = context.getSharedPreferences(APP_SHARED_PREFS, Activity.MODE_PRIVATE);
this._prefsEditor = _sharedPrefs.edit();
}
public String getDifficulty() {
return _sharedPrefs.getString(KEY_DIFFICULTY, "");
}
public void saveSmsBody(String text) {
_prefsEditor.putString(KEY_DIFFICULTY, text);
_prefsEditor.commit();
}

我的GameLoopThread课程：
import android.graphics.Canvas;
public class GameLoopThread extends Thread {
static final long FPS = 10;
private GameView view;
private boolean running = false;
public GameLoopThread(GameView view) {
this.view = view;
}
public void setRunning(boolean run) {
running = run;
}
@Override
public void run() {
long ticksPS = 1000 / FPS;
long startTime;
long sleepTime;
while (running) {
Canvas c = null;
startTime = System.currentTimeMillis();
try {
c = view.getHolder().lockCanvas();
synchronized (view.getHolder()) {
view.onDraw(c);
}
} finally {
if (c != null) {
view.getHolder().unlockCanvasAndPost(c);
}
}
sleepTime = ticksPS - (System.currentTimeMillis() - startTime);
try {
if (sleepTime > 0)
sleep(sleepTime);
else
sleep(10);
} catch (Exception e) {}
}
}
}
我目前正试图通过单选按钮来改变游戏的难度，但目前正在点击正在崩溃的单选按钮。

（代码是从这个问题转储Android Shared Preferences）
创建课程AppPreferences
public class AppPreferences {
public static final String KEY_DIFFICULTY = "difficulty";
private static final String APP_SHARED_PREFS = AppPreferences.class.getSimpleName(); // Name of the file -.xml
private SharedPreferences _sharedPrefs;
private Editor _prefsEditor;
public AppPreferences(Context context) {
this._sharedPrefs = context.getSharedPreferences(APP_SHARED_PREFS, Activity.MODE_PRIVATE);
this._prefsEditor = _sharedPrefs.edit();
}
public String getDifficulty() {
return _sharedPrefs.getString(KEY_DIFFICULTY, "");
}
public void saveDifficulty(String text) {
_prefsEditor.putString(KEY_DIFFICULTY, text);
_prefsEditor.commit();
}
}
在班级中定义成员
private AppPreferences _appPrefs;
在onCreate中执行此操作
public GameView(Context context, AttributeSet attributeSet) {
super(context);
_appPrefs = new AppPreferences(getApplicationContext());
String difficulty = _appPrefs.getDifficulty();
并在您选择时进行设置
_appPrefs.saveDifficulty("1"); //or "2" or "3"

使用我想调用和修改的简单静态setter和getter方法解决了这个问题。
