1. 样式与主题

<?xml version="1.0" encoding="utf-8"?> 
<resources> 
  <style name="MyRedTheme" parent="android:Theme.Light"> 
    <item name="android:textAppearance">@style/MyRedTextAppearance</item> 
  </style> 
  <style name="MyRedTextAppearance" parent="@android:style/TextAppearance"> 
    <item name="android:textColor">#F00</item> 
    <item name="android:textStyle">bold</item> 
  </style> 
</resources> 
<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:orientation="vertical" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    > 
<TextView 
     
    android:layout_width="fill_parent"  
    android:layout_height="wrap_content"  
    android:text="This is red, isn't it?" 
    /> 
</LinearLayout> 
2.

public class RedTextView extends TextView{ 
    public RedTextView(Context context, AttributeSet attrs) { 
        super(context, attrs); 
        setTextColor(Color.RED); 
    } 
} 
<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:orientation="vertical" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    > 
<org.example.RedTextView   
    android:layout_width="fill_parent"  
    android:layout_height="wrap_content"  
    android:text="This is red, isn't it?" 
    /> 
</LinearLayout> 

Xcode代码提示生成源代码程序块默认格式如下，注意左花括号的位置：

if ( condition ) {
    do ...
}

因为以前的使用习惯，我想让自动生成的左右花括号都单独成行，变成下面的样子：

if ( condition )
{
    do ...
}

在Terminal里面，运行下面命令，然后重启Xcode：

defaults write com.apple.Xcode XCCodeSenseFormattingOptions -dict BlockSeparator "\n"

import java.util.HashMap;
import java.util.List;

import android.content.Context;
import android.view.View;
import android.view.ViewGroup;
import android.widget.SimpleAdapter;

public class SpecialAdapter extends SimpleAdapter {
	private int[] colors = new int[] { 0x30FF0000, 0x300000FF };

	public SpecialAdapter(Context context, List<HashMap<String, String>> items, int resource, String[] from, int[] to) {
		super(context, items, resource, from, to);
	}

	@Override
	public View getView(int position, View convertView, ViewGroup parent) {
	  View view = super.getView(position, convertView, parent);
	  int colorPos = position % colors.length;
	  view.setBackgroundColor(colors[colorPos]);
	  return view;
	}
}

SpecialAdapter adapter = new SpecialAdapter(this,fillMaps,R.layout.grid_item,from,to);
...
