enter image description here嘿家伙我在我的Java 1类的工作结束我的项目。我们正在制作记忆/集中游戏。我的问题是，当我点击下一个活动的简单按钮时，应用程序崩溃。我尝试过使用片段和活动，但似乎无法正确使用它。我也尝试过在我的主要活动中使用我需要的布局，以查看是否可以显示它。即使这样，它只是在应用程序启动时崩溃。任何帮助，将不胜感激。xml布局崩溃加载Android应用程序
启动屏幕活动。
package com.bignerdranch.android.memory;
import android.app.Activity;
import android.content.Intent;
import android.media.AudioManager;
import android.media.MediaPlayer;
import android.os.Bundle;
import android.view.Menu;
import android.view.View;
import android.widget.Button;
import android.widget.CheckBox;
public class MemoryActivity extends Activity {
private Button mEasy;
private Button mMedium;
private Button mHard;
private CheckBox mSilence;
public MediaPlayer player;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_memory);
player = new MediaPlayer();
player = MediaPlayer.create(this, R.raw.mkstartmusic);
player.setAudioStreamType(AudioManager.STREAM_MUSIC);
player.setLooping(true);
player.start();
mEasy = (Button)findViewById(R.id.easy);
mEasy.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent easy = new Intent(getApplicationContext(), EasyGame.class);
startActivity(easy);
}
});
mMedium = (Button)findViewById(R.id.medium);
mMedium.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
}
});
mHard = (Button)findViewById(R.id.hard);
mHard.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
}
});
mSilence = (CheckBox)findViewById(R.id.silence);
mSilence.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if(mSilence.isChecked()) {
player.pause();
} else if(mSilence.isChecked() == false) {
player.start();
}
}
});
}
@Override
protected void onStop() {
super.onPause();
if (player != null){
player.stop();
if (isFinishing()){
player.stop();
player.release();
}
}
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.layout.activity_memory, menu);
return true;
}
}
次活动（容易的选择）
package com.bignerdranch.android.memory;
import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.View;
import android.widget.ImageButton;
public class EasyGame extends Activity {
private ImageButton buttOne;
private ImageButton buttTwo;
private ImageButton buttThree;
private ImageButton buttFour;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_easy);
buttOne = (ImageButton)findViewById(R.id.ImageButton01);
buttOne.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
}
});
buttTwo = (ImageButton)findViewById(R.id.ImageButton02);
buttTwo.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
}
});
buttThree = (ImageButton)findViewById(R.id.ImageButton03);
buttThree.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
}
});
buttFour = (ImageButton)findViewById(R.id.ImageButton04);
buttFour.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
}
});
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.layout.activity_easy, menu);
return true;
}
}
这是布局容易的选择

'应用程序崩溃'意味着每个人都搜索崩溃日志。没有人会检查代码。发布堆栈跟踪。 –
