enter image description here嘿傢伙我在我的Java 1類的工作結束我的項目。我們正在製作記憶/集中游戲。我的問題是，當我點擊下一個活動的簡單按鈕時，應用程序崩潰。我嘗試過使用片段和活動，但似乎無法正確使用它。我也嘗試過在我的主要活動中使用我需要的佈局，以查看是否可以顯示它。即使這樣，它只是在應用程序啓動時崩潰。任何幫助，將不勝感激。xml佈局崩潰加載Android應用程序
啓動屏幕活動。

import android.widget.ImageButton;
public class EasyGame extends Activity {

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;
