java - Android:键盘未显示在焦点上

Question

我的主要 Activity 中有一个用户名和密码字段，当我们启动应用程序时，键盘将聚焦在用户名字段上。

但是当您折叠键盘然后尝试单击用户名字段时，键盘不会显示，但它适用于密码字段。

这是我的代码:

activity_main.xml

 <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity">

    <RelativeLayout
        android:id="@+id/mainLayout"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_alignParentLeft="true"
        android:layout_alignParentStart="true"
        android:background="#ffffff">

        <EditText
            android:id="@+id/loginText"
            android:layout_width="150dp"
            android:layout_height="wrap_content"
            android:layout_centerHorizontal="true"
            android:layout_centerVertical="true"
            android:enabled="true"
            android:gravity="center"
            android:hint="Login ID"
            android:inputType="textEmailAddress"
            android:textIsSelectable="true"
            android:textStyle="normal" />

        <EditText
            android:id="@+id/passwordText"
            android:layout_width="150dp"
            android:layout_height="wrap_content"
            android:layout_alignLeft="@+id/loginText"
            android:layout_alignStart="@+id/loginText"
            android:layout_below="@+id/loginText"
            android:ems="10"
            android:enabled="true"
            android:foregroundGravity="center"
            android:gravity="center"
            android:hint="Password"
            android:inputType="textPassword" />

        <ImageView
            android:id="@+id/imageView"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_above="@+id/loginText"
            android:layout_alignParentEnd="true"
            android:layout_alignParentLeft="true"
            android:layout_alignParentRight="true"
            android:layout_alignParentStart="true"
            android:layout_alignParentTop="true"
            android:focusableInTouchMode="true"
            android:src="@drawable/img" />

        <Button
            android:id="@+id/loginButton"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_below="@+id/passwordText"
            android:layout_centerHorizontal="true"
            android:layout_marginTop="68dp"
            android:onClick="checkLogin"
            android:text="Login" />
    </RelativeLayout>

    <ScrollView
        android:id="@+id/ScrollView01"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent" />

</RelativeLayout>

MainActivity.java

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    // Start the background Firebase activity
    serviceIntent = new Intent(this, SendNotificationService.class);
    this.stopService(serviceIntent);

    //Attempt to show keyboard
    //RelativeLayout relativeLayout = (RelativeLayout)findViewById(R.id.mainLayout);
    //relativeLayout.clearFocus();

    // Clear userSession
    user_Session = null;

    this.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.menu_main, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
    int id = item.getItemId();

    //noinspection SimplifiableIfStatement
    if (id == R.id.action_settings) {
        return true;
    }

    return super.onOptionsItemSelected(item);
}

public void checkLogin(View view){
    EditText loginEditText = (EditText)findViewById(R.id.loginText);
    EditText passwordEditText = (EditText)findViewById(R.id.passwordText);
    login(loginEditText.getText().toString(), passwordEditText.getText().toString());
}

请帮助我调试问题。

删除loginText EditText 中的android:textIsSelectable="true" 行。
