如何删除已经放大到屏幕的布局

Question

I've created an in-app keyboard with two possible languages.

For each language there's a different layout (the root element of the layouts is merge). I have a 'switch' Button in every layout for switching between the languages.

I've tried to set the layout that currently shown as 'GONE' and then add the second layout, but it doesn't work and instead of changing the layout, it just adding the second layout, and showing it with the second together.

Here is the Class that handles my keyboard.

The place that I handle the language switching is found at the Switch-Case inside the function onClick, case: 'R.id.button_switch':

public class MyKeyboard extends LinearLayout implements View.OnClickListener {

private SparseArray<String> keyValues = new SparseArray<>();
private InputConnection inputConnection;
private Boolean isEnglish;
private Context con;
private View keb;

public MyKeyboard(Context context) {
    this(context, null, 0);
}
public MyKeyboard(Context context, AttributeSet attrs) {
    this(context, attrs, 0);
}
public MyKeyboard(Context context, AttributeSet attrs, int defStyleAttr) {
    super(context, attrs, defStyleAttr);
    init(context, attrs);
}
private void init(Context context, AttributeSet attrs) {
    con = context;
    //english(context);
    hebrew(context);
}

private void hebrew(Context context) {
    isEnglish = false;
    keb = LayoutInflater.from(context).inflate(R.layout.heb_keyboard, this, true);

    findViewById(R.id.button_enter).setOnClickListener(this);
    findViewById(R.id.button_delete).setOnClickListener(this);
    findViewById(R.id.button_switch).setOnClickListener(this);
    findViewById(R.id.button_alef).setOnClickListener(this);
    findViewById(R.id.button_b).setOnClickListener(this);
    findViewById(R.id.button_c).setOnClickListener(this);

    keyValues.put(R.id.button_alef, "א");
    keyValues.put(R.id.button_b, "b");
    keyValues.put(R.id.button_c, "c");
}

private void english(Context context) {
    isEnglish = true;
    keb = LayoutInflater.from(context).inflate(R.layout.en_keyboard, this, true);

    findViewById(R.id.button_enter).setOnClickListener(this);
    findViewById(R.id.button_delete).setOnClickListener(this);
    findViewById(R.id.button_switch).setOnClickListener(this);
    findViewById(R.id.button_a).setOnClickListener(this);
    findViewById(R.id.button_b).setOnClickListener(this);
    findViewById(R.id.button_c).setOnClickListener(this);

    keyValues.put(R.id.button_a, "a");
    keyValues.put(R.id.button_b, "b");
    keyValues.put(R.id.button_c, "c");
}

@Override
public void onClick(View view) {
    if (inputConnection == null)
        return;

    switch (view.getId()) {
        case R.id.button_delete:
            if (TextUtils.isEmpty(inputConnection.getSelectedText(0))) {
                inputConnection.deleteSurroundingText(1, 0);
            } else {
                inputConnection.commitText("", 1);
            }
            break;

        case R.id.button_enter:
            inputConnection.finishComposingText();
            this.setVisibility(INVISIBLE);
            break;

        case R.id.button_switch:
            if (isEnglish)
                hebrew(con);
            else
                english(con);
            break;

        default:
            inputConnection.commitText(keyValues.get(view.getId()), 1);
            break;
    }
}

public void setInputConnection(InputConnection ic) {
    inputConnection = ic;
}
}    

I need to find how to remove the previews layout that were inflated before, and then add the other layout.

Answer 1

如果setVisibility(GONE)未解决，则可以使用FrameLayout并通过以下方式更改其片段：

getSupportFragmentManager().beginTransaction().replace(R.id.main_container, fragment, newTag).commit();

Answer 2

尝试这个

View view = inflate(mContext, R.layout.en_keyboard, this);
