java.lang.RuntimeException：Canvas：試圖繪製太大的位圖

Question

<android.support.design.widget.FloatingActionButton 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:clickable="true" 
    app:fabSize="normal" 
    app:srcCompat="@mipmap/ic_launcher" 
    android:id="@+id/floatingActionButton" 
    android:layout_gravity="bottom|end" 
    android:layout_marginRight="20dp" 
    android:layout_marginBottom="20dp" 
    app:backgroundTint="#54ddde" /> 

目前，浮動按鈕的圖像是android。但我想改變爲'加'形象。

般這個

<android.support.design.widget.FloatingActionButton 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:clickable="true" 
    app:fabSize="normal" 
    android:src="@drawable/img_plus" 
    android:id="@+id/floatingActionButton" 
    android:layout_gravity="bottom|end" 
    android:layout_marginRight="20dp" 
    android:layout_marginBottom="20dp" 
    app:backgroundTint="#54ddde" /> 

但是我只改變形象，應用程序已經停止。我真的很尷尬。 有人可以幫助我。

這裏是日誌貓的錯誤。

做它progamatically，試試這個。

ImageView icon = new ImageView(this); // Create an icon 
    icon.setImageDrawable(getResources().getDrawable(R.drawable.add_user)); 

    //set the appropriate background for the main floating action button along with its icon 
    FloatingActionButton factionButton = new FloatingActionButton.Builder(this) 
      .setContentView(icon) 
      .setBackgroundDrawable(R.drawable.selector_floating_button) 
      .build();
