导航抽屉在单击事件时关闭

Question

---

我无法单击任何菜单项，也无法从右向左滑动以关闭抽屉，尽管每当打开抽屉并单击屏幕时，抽屉都会立即关闭。

我已经在堆栈溢出和Github上尝试过所有发布给类似问题的答案：

 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);
    }
}

}

Answer 1

在 BottomActivity 中将其添加到您的 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。
