【问题描述】:
我试图在单击按钮时在我的应用程序中显示底部工作表对话框。但是对话框正在部分打开。我想在单击按钮时完全打开对话框。
我已经尝试了以下代码。
MainActivity.java
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
View showModalBottomSheet = findViewById(R.id.as_modal);
showModalBottomSheet.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
//Initializing a bottom sheet
BottomSheetDialogFragment bottomSheetDialogFragment = new CustomBottomSheetDialogFragment();
//show it
bottomSheetDialogFragment.show(getSupportFragmentManager(), bottomSheetDialogFragment.getTag());
}
});
}
}
CustomBottomSheetDialogFragment.java
public class CustomBottomSheetDialogFragment extends BottomSheetDialogFragment {
@Override
public void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
private BottomSheetBehavior.BottomSheetCallback mBottomSheetBehaviorCallback = new BottomSheetBehavior.BottomSheetCallback() {
@Override
public void onStateChanged(@NonNull View bottomSheet, int newState) {
if (newState == BottomSheetBehavior.STATE_HIDDEN) {
dismiss();
}
}
@Override
public void onSlide(@NonNull View bottomSheet, float slideOffset) {
}
};
@Override
public void setupDialog(Dialog dialog, int style) {
super.setupDialog(dialog, style);
View contentView = View.inflate(getContext(), R.layout.dialog_modal, null);
dialog.setContentView(contentView);
CoordinatorLayout.LayoutParams layoutParams =
(CoordinatorLayout.LayoutParams) ((View) contentView.getParent()).getLayoutParams();
CoordinatorLayout.Behavior behavior = layoutParams.getBehavior();
if (behavior != null && behavior instanceof BottomSheetBehavior) {
((BottomSheetBehavior) behavior).setBottomSheetCallback(mBottomSheetBehaviorCallback);
}
}
}
