无法从 OnClickListener 启动 Andengine Activity
Trouble launching Andengine Activity from OnClickListener
我有一个 Activity 仅用于显示主菜单,然后我想在单击按钮后启动一个 Andengine Activity。
public class MainMenuActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.main_menu_layout);
TextView nadpis = (TextView) findViewById(R.id.nadpis);
Typeface tf = Typeface.createFromAsset(getAssets(), "font/DiamondsPearls.ttf");
nadpis.setTypeface(tf);
Button playGame = (Button)findViewById(R.id.playgame);
playGame.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Intent intent = new Intent(this, MonsterTap.class);
startActivity(intent);
}
});
}
}
我看到一条关于行 Intent intent = new Intent(this, MonsterTap.class);
的错误
cannot resolve constructor intent(anonymous android.view.View.OnClickListener, java.lang.class)
我做错了什么?
将 Intent intent = new Intent(this, MonsterTap.class);
替换为 Intent intent = new Intent(MainMenuActivity.this, MonsterTap.class);
以正确传递意图 Context
。
如您所写,this
关键字指的是代表您的 OnClickListener
.
