Android: disegnabile accanto a TextView con peso per ogni TextView in LinearLayout

Question

Sto cercando di ottenere il risultato come mostrato in Pic1. Provato a impostare la gravità, il paddingleft ecc., Ma l'immagine estraibile si trova all'estremità destra e non accanto a Testo (mostrato nella foto 2 ). Qualcuno può suggerire come allineare l'immagine accanto a TextView? Anche come impostare la dimensione del drawable?

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:layout_width="fill_parent" 
android:layout_height="wrap_content" 
android:orientation="horizontal" 
android:background="@drawable/separator" 
    android:padding="10dp"> 

<TextView 
    android:id="@+id/sms" 
    android:layout_width="0dp" 
    android:layout_height="wrap_content" 
    android:layout_marginLeft="2dp" 
    android:layout_marginRight="2dp" 
    android:layout_weight="1" 
    android:drawableEnd="@drawable/message" 
    android:drawableRight="@drawable/message" 
    android:gravity="center" 
    android:paddingLeft="3dp" 
    android:paddingRight="3dp" 
    android:text="SMS" /> 

<TextView 
    android:id="@+id/call" 
    android:layout_width="0dp" 
    android:layout_height="wrap_content" 
    android:layout_weight="1" 
    android:drawableEnd="@drawable/call" 
    android:drawableRight="@drawable/call" 
    android:gravity="center" 
    android:text="CALL" /> 

<TextView 
    android:id="@+id/email" 
    android:layout_width="0dp" 
    android:layout_height="wrap_content" 
    android:layout_weight="1" 
    android:gravity="center" 
    android:drawableEnd="@drawable/mail" 
    android:drawablePadding="3dp" 
    android:drawableRight="@drawable/mail" 
    android:text="MAIL" /> 

Answer 1

Creato un pulsante personalizzato che pretende molto bisogno di nesting di layout e in grado di allineare le immagini disegnabili come richiesto.

button.xml file di layout:

<Button xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@+id/custom_button" 
    style="@style/custom_button" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_gravity="center" 
    android:drawablePadding="5dp" 
    android:gravity="center" /> 

personalizzato Button Classe:

public class DrawableAlignedButton extends RelativeLayout { 

    private View view; 
    private Button button; 

    /** 
    * @param context 
    *   used to inflate the View. 
    * @param attrs 
    *   XML defined attributes. 
    */ 
    public DrawableAlignedButton(final Context context, final AttributeSet attrs) { 
    super(context, attrs); 
    init(context, attrs); 
    } 

    /** 
    * @param context 
    *   used to inflate the View. 
    */ 
    public DrawableAlignedButton(final Context context) { 
    super(context); 
    init(context, null); 
    } 

    /** 
    * @param context 
    *   used to inflate the View. 
    * @param attrs 
    *   XML defined attributes. 
    * @param style 
    *   the style for the View. 
    */ 
    public DrawableAlignedButton(final Context context, final AttributeSet attrs, final int style) { 
    super(context, attrs, style); 
    init(context, attrs); 
    } 

    private void init(final Context context, final AttributeSet attributeSet) { 
    view = ((Activity) getContext()).getLayoutInflater().inflate(R.layout.button, this, true); 
    button = (Button) view.findViewById(R.id.custom_button); 

    String buttonText = null; 
    int drawableStart = 0; 
    int drawableEnd = 0; 

    if (attributeSet != null) { 
     final TypedArray a = context.getTheme().obtainStyledAttributes(attributeSet, R.styleable.CustomButtonStyle, 0, 0); 
     buttonText = a.getString(R.styleable.CustomButtonStyle_buttonText); 
     drawableStart = a.getResourceId(R.styleable.CustomButtonStyle_buttonDrawableStart, 0); 
     drawableEnd = a.getResourceId(R.styleable.CustomButtonStyle_buttonDrawableEnd, 0); 
     a.recycle(); 
    } 

    FontUtil.getInstance(context).useNormalRegularFont(button); 

    if (buttonText != null) { 
     button.setText(buttonText); 
    } 

    button.setCompoundDrawablesRelativeWithIntrinsicBounds(drawableStart, 0, drawableEnd, 0); 
    } 

    /** 
    * Sets the button text. 
    * 
    * @param text 
    *   the text to be set. 
    */ 
    public void setButtonText(final String text) { 
    if (button != null) { 
     button.setText(text); 
    } 
    } 

    /** 
    * Sets the drawable to the button. 
    * 
    * @param drawableStart 
    *   the drawable to set at the beginning of the text. 
    * @param drawableEnd 
    *   the drawable to set at the end of the text. 
    */ 
    public void setDrawableStart(final int drawableStart, final int drawableEnd) { 
    if (button != null) { 
     button.setCompoundDrawablesRelativeWithIntrinsicBounds(drawableStart, 0, drawableEnd, 0); 
    } 
    } 

} 

Come si usa in XML:

<com.package.view.DrawableAlignedButton 
     xmlns:drawableAlignedButton="http://schemas.android.com/apk/res-auto" 
     android:layout_width="0dp" 
     android:layout_height="wrap_content" 
     android:layout_weight="1" 
     android:background="@drawable/transparent_button_selector" 
     drawableAlignedButton:buttonDrawableStart="@drawable/small_active" 
     drawableAlignedButton:buttonText="Button Text" /> 

Answer 2

cercare di costruire intorno a questo.

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:background="@android:color/transparent" 
    android:orientation="horizontal" 
    android:padding="10dp"> 

    <LinearLayout 
     android:layout_width="0dp" 
     android:layout_height="wrap_content" 
     android:gravity="center" 
     android:layout_weight="1"> 

     <TextView 
      android:id="@+id/sms" 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:layout_marginLeft="2dp" 
      android:layout_marginRight="2dp" 
      android:gravity="center" 
      android:drawableRight="@drawable/message" 
      android:text="SMS" /> 
    </LinearLayout> 

    <LinearLayout 
     android:layout_width="0dp" 
     android:layout_height="wrap_content" 
     android:gravity="center" 
     android:layout_weight="1"> 

     <TextView 
      android:id="@+id/call" 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:drawableRight="@drawable/call" 

      android:gravity="center" 
      android:text="CALL" /> 
    </LinearLayout> 

    <LinearLayout 
     android:layout_width="0dp" 
     android:layout_height="wrap_content" 
     android:gravity="center" 
     android:layout_weight="1"> 

     <TextView 
      android:id="@+id/email" 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:drawableRight="@drawable/mail" 
      android:gravity="center" 
      android:text="MAIL" /> 
    </LinearLayout> 
</LinearLayout> 

Answer 3

Il problema principale è che, si sta impostando il layoutWidth = 0DP e peso 1. Questo rende ogni TextView prendere larghezza massima in base al peso. Il drawableRight/drawableEnd imposta la risorsa drawable da disegnare sul bordo più a destra della vista. Se vuoi mantenere questo layout, basta avvolgerlo in un altro viewGroup come @Dhinakaran ha mostrato. Un approccio migliore sarebbe utilizzare un layout di scheda .

Invece di utilizzare più layout lineari, è possibile utilizzare un layout relativo.

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout

    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"

      android:src="@android:drawable/btn_star"/> 
    </RelativeLayout> 

    <RelativeLayout

      android:layout_centerVertical="true" 
      android:layout_toEndOf="@+id/textView2" 
      android:layout_toRightOf="@+id/textView2" 
      android:src="@android:drawable/btn_star"/> 
    </RelativeLayout> 

    <RelativeLayout 
     android:layout_width="match_parent" 
     android:layout_height="50dp" 
     android:layout_gravity="bottom" 
     android:layout_weight=".33" 
     android:gravity="center_horizontal|center_vertical">

      android:text="Small Text" 
      android:textAppearance="?android:attr/textAppearanceSmall"/> 

     <ImageView 
      android:id="@+id/imageView3" 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:layout_centerVertical="true" 
      android:layout_toEndOf="@+id/textView3" 
      android:layout_toRightOf="@+id/textView3" 
      android:src="@android:drawable/btn_star"/> 
    </RelativeLayout> 
</LinearLayout>
