ベースの活動にナビゲーション引き出しを作成し、主な活動に延びているが、何の結果が主な活動ではありません
私のコードは次のとおりです。BaseActivity Javaコード：
public class BaseActivity extends AppCompatActivity {
DrawerLayout mDrawerLayout;
ListView mDrawerList;
String[] items;
ActionBarDrawerToggle mDrawerToggle;
Toolbar toolbar;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawerList = (ListView) findViewById(R.id.drawer_list);
toolbar = (Toolbar) findViewById(R.id.tool_bar);
setSupportActionBar(toolbar);
items = getResources().getStringArray(R.array.menu);
mDrawerList.setAdapter(new ArrayAdapter<String>(this, R.layout.drawer_list_item, items));
mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout, toolbar, R.string.drawer_open, R.string.drawer_close){
};
mDrawerLayout.addDrawerListener(mDrawerToggle);
mDrawerList.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
selectItem(position);
mDrawerLayout.closeDrawer(mDrawerList);
}
});
}
public void selectItem(int position){
Intent intent;
switch (position)
{
case 0:
intent = new Intent(this,OneActivity.class);
startActivity(intent);
break;
case 1:
intent = new Intent(this,TwoActivity.class);
startActivity(intent);
break;
}
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
if (mDrawerToggle.onOptionsItemSelected(item)) {
return true;
}
return super.onOptionsItemSelected(item);
}
@Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
mDrawerToggle.syncState();
}
@Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
mDrawerToggle.onConfigurationChanged(newConfig);
}
}
そして、ここに私のXMLコードです：
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:toolbar="http://schemas.android.com/apk/res-auto"
android:id="@+id/tool_bar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@color/colorAccent"
toolbar:navigationIcon="@drawable/ic_navigation">
</android.support.v7.widget.Toolbar>
<android.support.v4.widget.DrawerLayout
android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<FrameLayout
android:id="@+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<ListView
android:id="@+id/drawer_list"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:background="@color/colorAccent"
android:choiceMode="singleChoice"
android:divider="@android:color/holo_blue_dark"
android:dividerHeight="1dp">
</ListView>
</android.support.v4.widget.DrawerLayout>
</LinearLayout>
そしてここMainActivityです：
public class MainActivity extends BaseActivity {
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(layout.activity_main);
}
}
は私に正しい答えを示唆して
