Question

我已经采用了Calroid的示例代码并在我的项目中实现了相同的代码。 Follwing是代码。但我得到一个例外您必须在每个案例中提供layout_width属性。我在我的项目中已经尝试了几种方法，但仍然遇到同样的错误。

活动代码

public class CustomActivity extends AppCompatActivity {
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.custom_layout);


            // Set a toolbar to replace the action bar.
            Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
            if (toolbar != null) {
                setSupportActionBar(toolbar);
            }
            getSupportActionBar().setDisplayHomeAsUpEnabled(true);


            FrameLayout frameLayout = (FrameLayout)findViewById(R.id.frame_container);


            CaldroidFragment caldroidFragment = new CaldroidFragment();
            Bundle args = new Bundle();
            Calendar cal = Calendar.getInstance();
            args.putInt(CaldroidFragment.MONTH, cal.get(Calendar.MONTH) + 1);
            args.putInt(CaldroidFragment.YEAR, cal.get(Calendar.YEAR));
            caldroidFragment.setArguments(args);

            FragmentTransaction t = getSupportFragmentManager().beginTransaction();
            t.replace(R.id.calendar1, caldroidFragment);
            t.commit();




        }

        @Override
        public boolean onCreateOptionsMenu(Menu menu) {

            return super.onCreateOptionsMenu(menu);
        }

        @Override
        public boolean onOptionsItemSelected(MenuItem item) {
            switch (item.getItemId()) {
                case android.R.id.home:
                    finish();
                    return true;
            }

            return super.onOptionsItemSelected(item);
        }

        @Override
        public void onBackPressed() {
            // TODO Auto-generated method stub
            super.onBackPressed();
            // Create the interstitial.


         }}

XML代码custom_layout.xml

<android.support.design.widget.CoordinatorLayout
            xmlns:android="http://schemas.android.com/apk/res/android"
            android:layout_width="match_parent"
           android:id="@+id/cordinationLayout"
           android:layout_height="match_parent">

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:orientation="vertical">

            <include  layout="@layout/app_bar"/>


        <FrameLayout
            android:id="@+id/calendar1"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:orientation="vertical" >
            </FrameLayout>
        </LinearLayout>

    </android.support.design.widget.CoordinatorLayout>

Answer 1

查看app_bar文件夹中的layout文件。我认为那里缺少layout_width attribute。将其设置为android:layout_width="match_parent"或android:layout_width="wrap_content"（取决于哪些匹配更好）。

Answer 2

尝试将宽度和高度设置为包含的布局。

      <include  
        layout="@layout/app_bar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"/>
