Android：鍵盤沒有顯示onfocus

Question

我在我的主要活動中有一個用戶名和密碼字段，當我們啓動應用程序時，鍵盤來自用戶名字段。

但是，當您摺疊鍵盤，然後嘗試單擊username字段時，鍵盤不顯示，但它適用於password字段。

這裏是我的代碼：

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()); 
} 

請幫我調試的問題。

Answer 1

在loginText EditText中刪除android:textIsSelectable="true"行。
