我无法单击任何菜单项，也无法从右向左滑动以关闭抽屉，但每当抽屉打开并单击屏幕时，它都会立即关闭。
我几乎尝试了在 Stack Overflow 和 Github 上发布的类似问题的所有答案:
public class BottomActivity extends AppCompatActivity
implements GestureOverlayView.OnGesturePerformedListener {
RadioGroup radioGroup;
RadioButton Rd1, Rd2, Rd3, Rd4;
DrawerLayout drawer;
@SuppressLint({"RtlHardcoded", "ClickableViewAccessibility"})
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate( savedInstanceState );
setContentView( R.layout.activity_bottom );
new GestureOverlayView( this );
Objects.requireNonNull( getSupportActionBar() ).setDisplayOptions( ActionBar.DISPLAY_SHOW_CUSTOM );
getSupportActionBar().setCustomView( R.layout.abs_layout_home );
radioGroup = findViewById( R.id.radioGroup );
Rd1 = findViewById( R.id.radioButton );
Rd2 = findViewById( R.id.radioButton2 );
Rd3 = findViewById( R.id.radioButton3 );
Rd4 = findViewById( R.id.radioButton4 );
radioGroup.setOnCheckedChangeListener( new RadioGroup.OnCheckedChangeListener() {
@Override
public void onCheckedChanged(RadioGroup group, int checkedId) {
if (Rd1.isChecked()) {
Intent intent = new Intent( getApplicationContext(), BottomActivity.class );
startActivity( intent );
}
if (Rd2.isChecked()) {
Intent intent1 = new Intent( getApplicationContext(), DashBoard.class );
startActivity( intent1 );
}
if (Rd3.isChecked()) {
Intent intent2 = new Intent( getApplicationContext(), SettingsActivity.class );
startActivity( intent2 );
} else {
if (Rd4.isChecked()) {
Intent intent3 = new Intent( getApplicationContext(), Messages.class );
startActivity( intent3 );
}
}
}
} );
}
@Override
public void onBackPressed() {
if (drawer.isDrawerOpen( GravityCompat.START )) {
drawer.closeDrawer( GravityCompat.START );
} else {
super.onBackPressed();
}
}
public void onDrawerSlide() {
DrawerLayout drawerLayout = findViewById( R.id.DrawerLayout);
drawerLayout.addDrawerListener(
new DrawerLayout.DrawerListener() {
@Override
public void onDrawerSlide(@NonNull View view, float v) {
}
@Override
public void onDrawerOpened(@NonNull View view) {
}
@Override
public void onDrawerClosed(@NonNull View view) {
}
@Override
public void onDrawerStateChanged(int i) {
}
}
);
}
@Override
public void onGesturePerformed(GestureOverlayView overlay, Gesture gesture) {
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle item selection
switch (item.getItemId()) {
case R.id.nav_profile:
startActivity( new Intent(BottomActivity.this, ProfileActivity.class));
return true;
case R.id.nav_settings:
startActivity( new Intent( BottomActivity.this, SettingsActivity.class));
return true;
default:
return super.onOptionsItemSelected(item);
}
}
}

最佳答案
在BottomActivity中将其添加到onCreate中:
NavigationView nav_view;
nav_view = findViewById(R.id.nav_view); //select nav_view from activity_drawer_layout
nav_view.setNavigationItemSelectedListener(this);
在activity_drawer_layout.xml中，将NavigationView放在DrawerLayout的结束标记上方。
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout

关于java - 抽屉导航在单击事件时关闭，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/56401363/
