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"/>

try

edit.setInputType(InputType.TYPE_NULL);

edit.setEnabled(false);

已经提供了很多有效的答案，但我认为我们可以使用以下简单方法做得更好

//set focus to input field
private fun focusHere() {
    findViewById<TextView>(R.id.input).requestFocus()
}

使用任何其他视图id来设置该视图的焦点，以代替R.id.input中的输入。

ListView中的EditText无法正常工作。使用EditText时，最好将TableLayout与自动生成的行一起使用。

简单可靠的解决方案，只需重写此方法：

@Override
public boolean dispatchTouchEvent(MotionEvent ev) {
    View v = getCurrentFocus();

    if (v != null &&
            (ev.getAction() == MotionEvent.ACTION_UP || ev.getAction() == MotionEvent.ACTION_MOVE) &&
            v instanceof EditText &&
            !v.getClass().getName().startsWith("android.webkit.")) {
        int scrcoords[] = new int[2];
        v.getLocationOnScreen(scrcoords);
        float x = ev.getRawX() + v.getLeft() - scrcoords[0];
        float y = ev.getRawY() + v.getTop() - scrcoords[1];

        if (x < v.getLeft() || x > v.getRight() || y < v.getTop() || y > v.getBottom())
            hideKeyboard(this);
    }
    return super.dispatchTouchEvent(ev);
}

public static void hideKeyboard(Activity activity) {
    if (activity != null && activity.getWindow() != null && activity.getWindow().getDecorView() != null) {
        InputMethodManager imm = (InputMethodManager) activity.getSystemService(Context.INPUT_METHOD_SERVICE);
        imm.hideSoftInputFromWindow(activity.getWindow().getDecorView().getWindowToken(), 0);
    }
}

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。
