当我尝试从一个活动转移到另一个活动时，它说应用已停止。
两项活动
Welcome.java
public class Welcome extends AppCompatActivity {
ActionBar actionBar;
DrawerLayout drawerLayout;
NavigationView navigationView;
TextView textView;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Get the view from singleitemview.xml
setContentView(R.layout.welcome);

setSupportActionBar(toolbar);

actionBar.setHomeAsUpIndicator(R.drawable.ic_menu_white_24dp);
actionBar.setDisplayHomeAsUpEnabled(true);
textView = (TextView) findViewById(R.id.txtwelcome);
drawerLayout = (DrawerLayout) findViewById(R.id.navigation_drawer_layout);
navigationView = (NavigationView) findViewById(R.id.navigation_view);
if (navigationView != null) {
setupNavigationDrawerContent(navigationView);
}
setupNavigationDrawerContent(navigationView);
}
@Override
public boolean onCreateOptionsMenu(Menu menu){
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
@Override

drawerLayout.closeDrawer(GravityCompat.START);
return true;
case R.id.item_navigation_drawer_settings:

drawerLayout.closeDrawer(GravityCompat.START);
textView.setText(menuItem.getTitle());
Toast.makeText(Welcome.this, "Welcome" + menuItem.getTitle().toString(), Toast.LENGTH_SHORT).show();
drawerLayout.closeDrawer(GravityCompat.START);
Intent intent = new Intent(Welcome.this, SettingsActivity.class);
startActivity(intent);
return true;
case R.id.item_navigation_drawer_help_and_feedback:
menuItem.setChecked(true);
Toast.makeText(Welcome.this, menuItem.getTitle().toString(), Toast.LENGTH_SHORT).show();
drawerLayout.closeDrawer(GravityCompat.START);
return true;
}
return true;
}
});
}
}
追踪：case R.id.item_navigation_drawer_gallery:
我正在从这里开始另一项活动。它说，＆＃34;不幸的是，App被停止＆＃34;。

如果有人介意帮助我，我将不胜感激。如果您需要xmls来查找错误，我也可以上传它。谢谢!!
答案 0 :(得分：0)
您的位图太大，这就是您收到OOM错误的原因，请尝试缩小比例以便解码可以正常工作：
BitmapFactory.Options options = new BitmapFactory.Options();
options.inSampleSize = 5;
但这样做我猜你的图像会模糊不清：
由于我们不想要您可以按照this指南有效加载位图。

您可以尝试在android:largeHeap="true"文件的应用标记中设置AndroidManifest.xml。如下所示：
<application
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:largeHeap="true" />
