当您的活动打开时，键盘会自动可见，这会导致EditText聚焦。您可以通过在manifest.xml文件的活动标记中写入以下行来禁用键盘。

android:windowSoftInputMode="stateAlwaysHidden|adjustPan"

它可以通过继承EditText并重写onTouchEvent来实现。

class NonFocusableEditText: EditText {

    constructor(context: Context): super(context)
    constructor(context: Context, attrs: AttributeSet?): super(context, attrs)
    constructor(context: Context, attrs: AttributeSet?, defStyleAttr: Int): super(context, attrs, defStyleAttr)

    override fun onTouchEvent(event: MotionEvent?): Boolean {
        return if (isFocusable) super.onTouchEvent(event) else false
    }
}

然后，您可以像普通的EditText一样在版面中使用它：

<com.yourpackage.NonFocusableEditText
        android:id="@+id/editText"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"    
        android:hint="@string/your_hint"
        android:imeOptions="actionDone"
        android:inputType="textNoSuggestions" />

在父布局（例如LinearLayout或ConstraintLayout）中添加标签android:focusableInTouchMode=“true”和android:focusable=“true”将解决该问题。

<!-- Dummy item to prevent AutoCompleteTextView from receiving focus -->
<LinearLayout
    android:focusable="true" 
    android:focusableInTouchMode="true"
    android:layout_width="0px" 
    android:layout_height="0px"/>

<!-- :nextFocusUp and :nextFocusLeft have been set to the id of this component
to prevent the dummy from receiving focus again -->
<AutoCompleteTextView android:id="@+id/autotext"
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content"
    android:nextFocusUp="@id/autotext" 
    android:nextFocusLeft="@id/autotext"/>

当按下按钮时，我使用以下代码阻止EditText窃取焦点。

addButton.setOnClickListener(new OnClickListener() {
    public void onClick(View v) {
        View focused = internalWrapper.getFocusedChild();
        focused.setVisibility(GONE);
        v.requestFocus();
        addPanel();
        focused.setVisibility(VISIBLE);
    }
});

Basically, hide the edit text and then show it again. This works for me as the EditText is **not** in view so it doesn't matter whether it is showing.

You could try hiding and showing it in succession to see if that helps it lose focus.

在Manifest.xml文件的活动标记中添加android:windowSoftInputMode=“stateAlwaysHidden”。

最迟但最简单的答案，只需将其添加到XML的父布局中即可。

android:focusable="true" 
android:focusableInTouchMode="true"
