用户单击 EditText 时如何禁用软键盘显示？

Question

I created a custom keyboard using CardView, so I don't need the software keyboard when I have an EditText. The thing now is that when I click on EditText the virtual keyboard pops up, is there a way to disable the virtual keyboard?

Here is my fragment code:

public class FragmentQuestion1 extends Fragment {

    private EditText mEditTextQuestion1;

    @Nullable
    @Override
    public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {

        View view = inflater.inflate(R.layout.fragment_question_1, container, false);

        mEditTextQuestion1 = view.findViewById(R.id.edit_text_question_1);
        MyKeyboard keyboard = view.findViewById(R.id.keyboard);
        mEditTextQuestion1.setRawInputType(InputType.TYPE_CLASS_TEXT);
        mEditTextQuestion1.setTextIsSelectable(true);

        InputConnection ic = mEditTextQuestion1.onCreateInputConnection(new EditorInfo());
        keyboard.setInputConnection(ic);

        mEditTextQuestion1.addTextChangedListener(new NumberTextWatcher(mEditTextQuestion1));

mEditTextQuestion1.setOnFocusChangeListener(new View.OnFocusChangeListener() {
            @Override
            public void onFocusChange(View view, boolean hasFocus) {
                if (hasFocus) {
                    getActivity().getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);
                } else {

                }
            }
        });

        return view;
    }

Here is the way I used the EditText in my xml file:

<EditText
            android:id="@+id/edit_text_question_1"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_marginLeft="8dp"
            android:layout_marginRight="8dp"
            android:backgroundTint="#FFFFFF"
            android:inputType="number"
            android:gravity="center"
            android:focusable="true"
            android:focusableInTouchMode="true"
            android:textIsSelectable="true"/>

Edit: Sorry it seems on Focus change is to early as this method is about hiding a softKeyboard not preventing it from showing.

Use an onClickListener works better but you will probably see the keyboard briefly.

And then hide the keyboard with InputMethodManager

See Close/hide the Android Soft Keyboard

Even onClick Seem to be unreliable due to timing issues.

But some example code that works most of the time.

public class MainActivity extends AppCompatActivity {


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        final EditText message = (EditText) findViewById(R.id.message);

        message.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                hideSoftKeyboard(v);
            }
        });

    }

    public void hideSoftKeyboard(View view) {
        InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
        imm.hideSoftInputFromWindow(view.getWindowToken(), 0);
    }
}

Answer 2

I found a solution that works fine and is pretty easy:

Just use mEditTextQuestion1.setEnabled(false); in the inCreateView method to make the EditText not clickable. In my case then the color of the EditText changed to a brighter dark so I added android:textColor="#000" to my xml file.

I had a very similar issue and was able to solve it as follows.

In the Android Manifest, you should add these lines to the activity

   <activity
        android:name=".activities.YourActivity"
        android:windowSoftInputMode="adjustResize|stateAlwaysHidden" />

Within the Activity Class (Java), add this to the onResume method. This will prevent the keyboard from popping up when the activity is resumed

@Override
    protected void onResume() {
        super.onResume();
        this.getWindow().setSoftInputMode(WindowManager.
                LayoutParams.SOFT_INPUT_STATE_HIDDEN); //hide keyboard when your activity is in use
    }

And I added this method to modify the EditText , and called it from onCreate, and whenever I modified my custom keyboard

private void setupSpinItemsCustomKeyboard() {
        Helper.hideAllKeyboard(YourActivity.this);
        fromEditText.setShowSoftInputOnFocus(false); //no response on keyboard touch
        fromEditText.requestFocus();
    }

and this to actually hide the keyboard

public static void hideAllKeyboard(Activity activity) {
        View view = activity.getCurrentFocus();
        if (view != null) {
            InputMethodManager imm = (InputMethodManager) activity.getSystemService(
                    Context.INPUT_METHOD_SERVICE);
            assert imm != null;
            imm.hideSoftInputFromWindow(view.getWindowToken(), 0);
        }
    }
