这是我的问题。 onOptionsItemSelected() 未在点击抽屉时调用。所以这是我的代码，非常简单......
public class MainActivity extends AppCompatActivity {
private Toolbar toolbar;
private DrawerLayout drawer;
private ActionBarDrawerToggle toggle;
private RelativeLayout aboutUs, feedBack;
private View view;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
view = findViewById(R.id.mainView);
aboutUs = (RelativeLayout) findViewById(R.id.list4);
feedBack = (RelativeLayout) findViewById(R.id.list5);
initToolbar();
drawerInit();
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
if (item.getItemId() == android.R.id.home) {
if (drawer.isDrawerOpen(Gravity.LEFT)) {
drawer.closeDrawer(Gravity.LEFT);
} else {
drawer.openDrawer(Gravity.LEFT);
}
}
return super.onOptionsItemSelected(item);
}
public void initToolbar() {
toolbar = (Toolbar) findViewById(R.id.toolbar_actionbar);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeButtonEnabled(true);
}
public void drawerInit() {
drawer = (DrawerLayout) findViewById(R.id.drawer);
toggle = new ActionBarDrawerToggle(
this, drawer, toolbar, R.string.drawer_open, R.string.drawer_close) {
@Override
public void onDrawerSlide(View drawerView, float slideOffset) {
float moveFactor = (drawerView.getWidth() * slideOffset);
view.setTranslationX(moveFactor);
}
@Override
public void onDrawerClosed(View drawerView) {
super.onDrawerClosed(drawerView);
}
};
drawer.addDrawerListener(toggle);
toggle.setDrawerIndicatorEnabled(true);
toggle.syncState();
}
@Override
protected void onDestroy() {
super.onDestroy();
}
我在 optionsItemSelected 回调中设置了断点，但这对抽屉点击不起作用。
但是抽屉打开了。那么问题出在哪里，我该如何解决呢？谢谢回答......................................
