Question

我正在设计一个日志:

UserName:  .....

Password:  .....

     LoginButton

When the activity starts, I want the focus to go to "UserName" textbox and the keyboard to appear.

www.un.org/Depts/DGACM/index_spanish.htm 我使用以下法典:。

    boolean checkFocus=user.requestFocus();
    Log.i("CheckFocus", ""+checkFocus);
    if(checkFocus==true)
    {
    InputMethodManager mgr = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
    mgr.showSoftInput(user, InputMethodManager.SHOW_IMPLICIT);
    }

I don t understand where to write this code to make the keyboard appear when the activity starts and focus is on the "UserName" editText box. Can anyone please guide me?

Answer 1

方案:

edittext.requestFocus();

Through xml:

<EditText...>
    <requestFocus />
</EditText>

Or call onClick method manually.

Answer 2

是的,我回答说,只是ed上了“条形”。档案:

        <activity android:name=".MainActivity"
        android:label="@string/app_name"
        android:windowSoftInputMode="stateAlwaysVisible" />

<代码>youredittext.requestFocus()。按活动分类

oncreate();

并使用上述法典

Answer 4

有了软键板残疾(只有外部键板才允许),我定下来,将 cur子最终转移到埃德特提尔:

editText.setSelection(editText.getText().length)

Answer 5

• 开展以下活动:

android:windowSoftInputMode="adjustResize"

3. 在意见成熟时确定重点:

fun setFocus(view: View, showKeyboard: Boolean = true){
    view.post {
        if (view.requestFocus() && showKeyboard)
            activity?.openKeyboard() // call extension function
    }
}

Answer 6

我知道它太晚了,但只有解决办法对我来说是行之有效的。

edittext.requestFocus()   
edittext.dispatchTouchEvent(MotionEvent.obtain(SystemClock.uptimeMillis(),SystemClock.uptimeMillis(),MotionEvent.ACTION_DOWN,0f,0f,0))    
edittext.dispatchTouchEvent(MotionEvent.obtain(SystemClock.uptimeMillis(),SystemClock.uptimeMillis(),MotionEvent.ACTION_UP,0f,0f,0))

我利用这一机会,以方案方式打开主要板块。

Answer 7

你可以写一下你的法典:

if (TextUtils.isEmpty(username)) {
    editTextUserName.setError("Please enter username");
    editTextUserName.requestFocus();
    return;
}

if (TextUtils.isEmpty(password)) {
    editTextPassword.setError("Enter a password");
    editTextPassword.requestFocus();
    return;
}

Answer 8

这在2023年对我做了出色的工作。

在你想要打开钥匙板的活动的明文档案中添加如下内容。

android:windowSoftInputMode="stateVisible"

在活动/筹资中增加

 if (editText.text.isNullOrEmpty()) {
            editText.requestFocus()
        }

If you do nt add this if clause keyboard will open in activity resume state as well.
