Android Google Login Button and Facebook sdk 4+ Bu

问题:

I Am developing an application which use google and facebook integration ...I want to fix height and width of those button...and i want to set Button Text Manualy...

i had tried so far

<com.facebook.login.widget.LoginButton
       xmlns:fb="http://schemas.android.com/apk/res-auto"
       android:id="@+id/connectWithFbButton"  
       android:layout_width="match_parent"
       android:layout_height="50dp"
       android:layout_marginLeft="10dp"
       android:layout_marginRight="10dp"
       android:text="@string/fbloginText"
       android:layout_marginTop="30dp"
/>

<com.google.android.gms.common.SignInButton
        android:id="@+id/signin"
        android:layout_width="match_parent"
        android:layout_height="50dp"
        android:text="@string/googleloginText" 
        android:layout_marginLeft="10dp"
        android:layout_marginRight="10dp"
        android:layout_marginTop="20dp"/>

although i had attemted something like this

    fb:login_text="Login"
    fb:logout_text="Logout"

         or 

    facebook:login_text="Login" 

But i Got Error::=>No resource identifier found for attribute 'login_text' in package 'com.test.b2c'

or in by coding

    loginButton = (LoginButton) findViewById(R.id.connectWithFbButton);
     loginButton.setText("Login");

Now My layout Look Something Like This

I also want to set Height And width of this buttons .. ... help me friends .....thx in advance

UPDATE

I have no direct problem in setting width what am I really concern is the inconsistent HEIGHT shown in the picture. I need to find better way(s) to make those buttons height equally nd set Text to those Button.

If we wanna change custom text of Facebook Login ..

Go to that Facebook library project And go to string.xml

you will find something like this

  <string name="com_facebook_loginview_log_in_button_long">Log in with facebook </string>

Replace this with your custom text

Although if you want to change custom text of Google Plus you can

From OnCreate call this

 setGooglePlusButtonText(signinButton,"your custom text");

//Text Change Method Of Google Plus

protected void setGooglePlusButtonText(SignInButton signInButton,
    String buttonText) {
    for (int i = 0; i < signInButton.getChildCount(); i++) {
    View v = signInButton.getChildAt(i);

       if (v instanceof TextView) {
           TextView tv = (TextView) v;
           tv.setTextSize(15);
           tv.setTypeface(null, Typeface.NORMAL);
           tv.setText(buttonText);
         return;
         }
      }
}

For Height inconsistancy of facebook i had add padding to Facebook Button XML

android:paddingTop="20dp"
android:paddingBottom="20dp"

回答2:

This xml code for style customizes my app's facebook login button like in the picture (in text and button size).

<com.facebook.login.widget.LoginButton
    android:id="@+id/login_button"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_marginTop="40dip"
    android:paddingTop="10dp"
    android:paddingBottom="10dp"
    android:textSize="20sp"
    facebook:com_facebook_login_text="Facebook"
    facebook:com_facebook_logout_text="Facebook" />

Result:

Add linear layout and add these 2 button in it :

<LinearLayout 
    android:id="@+id/parentLinear" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent"
    android:orientation="vertical" >

<com.facebook.login.widget.LoginButton
       xmlns:fb="http://schemas.android.com/apk/res-auto"
       android:id="@+id/connectWithFbButton"  
       android:layout_width="wrap_content"
       android:layout_height="50dp"
       android:layout_marginLeft="10dp"
       android:layout_marginRight="10dp"
       android:text="@string/fbloginText"
       android:layout_marginTop="30dp" />

<com.google.android.gms.common.SignInButton
        android:id="@+id/signin"
        android:layout_width="wrap_content"
        android:layout_height="50dp"
        android:text="@string/googleloginText" 
        android:layout_marginLeft="10dp"
        android:layout_marginRight="10dp"
        android:layout_marginTop="30dp" />
</LinearLayout>

This will give Correct Height, Width and Margin for both button

You have to change android:layout_width to either wrap_content, or a specific size, preferably in dp's (e.g. 20dp, 30dp, 40dp).

As for the error, it is probably shown because you didn't edit your strings.xml, try using Android Studio, it will automatically create these values for you, and will also show you a preview of your app.

回答5:

You just need to change the

android:layout_width="any size in dps"
android:layout_height="any size in dps"

and for setting the buttons manually you can concern with the specific docs. i,e check it or this is a good example.

回答6:

In your Facebook Widget add the following:

android:paddingTop="20dp"
android:paddingBottom="20dp"
loginView:login_text="your custom text here"

UPDATE

You also need to include this:

xmlns:loginView="http://schemas.android.com/apk/res-auto"

<com.facebook.login.widget.LoginButton
    xmlns:fb="http://schemas.android.com/apk/res-auto"
