ImageView를 클릭하면 응용 프로그램이 충돌합니다.

Question

코딩이 시작되었으므로 쉽게 할 수 있습니다.

HERE에 설명 된 지침에 따라 버튼 onClick을 ImageView onClick으로 변경했는데 (한 번 클릭 한 이미지가 다른 활동으로 이동 함) 작동하지 않는 것 같습니다. 내가 뭔가를 놓치고 있는지 궁금 하네. 누군가가 나를 도울 수 있다면, 그것은 좋지 않을까 :)

import android.content.Intent; 
 
import android.os.Bundle; 
 
import android.support.v7.app.AppCompatActivity; 
 
import android.support.v7.widget.Toolbar; 
 
import android.view.View; 
 
import android.view.Menu; 
 
import android.view.MenuItem; 
 
import android.widget.ImageView; 
 

 
public class MainActivity extends AppCompatActivity { 
 

 
    ImageView hotel; **//the image that gets clicked. Don't know if i need 
 
//this in the code or not. nothing seems to point to it 
 

 
    @Override 
 
    protected void onCreate(Bundle savedInstanceState) { 
 
     super.onCreate(savedInstanceState); 
 
     setContentView(R.layout.activity_main); 
 
     Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar); 
 
     setSupportActionBar(toolbar); 
 
     getSupportActionBar().setTitle(null); 
 
    } 
 

 
    public void goToHotelWebView (View view) { 
 
     Intent intent = new Intent(this, hotelwebview.class); 
 
     startActivity(intent); **//The code that I added in from the tutorial** 
 

 
    } 
 
    @Override 
 
    public boolean onCreateOptionsMenu(Menu menu) { 
 
     // Inflate the menu; this adds items to the action bar if it is present. 
 
     getMenuInflater().inflate(R.menu.menu_main, menu); 
 
     return true; 
 
    } 
 

 
    @Override 
 
    public boolean onOptionsItemSelected(MenuItem item) { 
 
     // Handle action bar item clicks here. The action bar will 
 
     // automatically handle clicks on the Home/Up button, so long 
 
     // as you specify a parent activity in AndroidManifest.xml. 
 
     int id = item.getItemId(); 
 

 
     //noinspection SimplifiableIfStatement 
 
     if (id == R.id.action_settings) { 
 
      return true; 
 
     } 
 

 
     return super.onOptionsItemSelected(item); 
 

 

 
     } 
 
    }

그리고 내 .XML 페이지

, 이미지는 온 클릭은 goToHotelWebView로 변경됩니다.

도움 주셔서 감사합니다.

EDIT = LOGCAT에서 오류가 발생했습니다 ... 읽는 중, 작업 표시 줄 디자인에 문제가있는 것 같지만 빈 슬레이트로 새 활동을 만들었으며 앱이 계속 충돌합니다.

오류 설명 : This Activity already has an action bar supplied by the window decor. Do not request Window.FEATURE_SUPPORT_ACTION_BAR and set windowActionBar to false in your theme to use a Toolbar instead.

이 AndroidManifest를 파일을 확인하고 활동 "hotelwebview"에 대한 주제를 확인합니다.

<activity 
      android:name=".hotelwebview" 
      android:configChanges="orientation|keyboardHidden|screenSize" 
      android:theme="@style/AppTheme"/> 

은 다음과 같이 테마를 수정 : 당신의 AndroidManifest.xml에

<!-- Base application theme. --> 
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar"> 
    <!-- Customize your theme here. --> 
    <item name="colorPrimary">@color/colorPrimary</item> 
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item> 
    <item name="colorAccent">@color/colorAccent</item> 
    <item name="windowActionBar">false</item> 
    <item name="windowNoTitle">true</item> 
</style>
