如何禁用BottomSheetDialogFragment手指拖动？
我看到了类似的问题,但它们都是关于BottomSheet而不是BottomSheetDialogFragment.
最佳答案
创建MyActivity如下：
public class MyActivity extends AppCompatActivity {
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_my);
new MyBottomSheetFragment().show(getSupportFragmentManager(),"tag");
}
public static class MyBottomSheetFragment extends BottomSheetDialogFragment {
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
BottomSheetDialog bottomSheetDialog = (BottomSheetDialog) super.onCreateDialog(savedInstanceState);
bottomSheetDialog.setContentView(R.layout.sample);
try {
Field mBehaviorField = bottomSheetDialog.getClass().getDeclaredField("mBehavior");
mBehaviorField.setAccessible(true);
final BottomSheetBehavior behavior = (BottomSheetBehavior) mBehaviorField.get(bottomSheetDialog);
behavior.setBottomSheetCallback(new BottomSheetBehavior.BottomSheetCallback() {
@Override
public void onStateChanged(@NonNull View bottomSheet,int newState) {
if (newState == BottomSheetBehavior.STATE_DRAGGING) {
behavior.setState(BottomSheetBehavior.STATE_EXPANDED);
}
}
@Override
public void onSlide(@NonNull View bottomSheet,float slideOffset) {
}
});
} catch (NoSuchFieldException e) {
e.printStackTrace();
} catch (IllegalAccessException e) {
e.printStackTrace();
}
return bottomSheetDialog;
}
}
}
R.layout.sample是一个简单的布局：
你会得到以下输出：
