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);
    }
}

<EditText
    android:layout_width="match_parent"
    android:layout_height="100dp"
    android:id="@+id/etComments"
    android:hint="Comments.."
    android:textSize="14dp"
    android:focusable="false"
    android:textStyle="italic"/>

我找到的唯一解决方案是：

创建LinearLayout（我不知道其他类型的Layout是否有效）设置属性android:focusable=“true”和android:focuableInTouchMode=“true“

并且EditText在开始活动后无法获得焦点

做这个，完成你的工作！

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

您可以通过创建布局宽度和高度设置为0dp的虚拟EditText，并请求对该视图进行聚焦来实现这一点。在xml布局中添加以下代码段：

<EditText
    android:id="@+id/editText0"
    android:layout_width="0dp"
    android:layout_height="0dp"
    android:hint="@string/dummy"
    android:ems="10" 
    >
     <requestFocus />
    </EditText>

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.
