自定义对话框设置style

  <style name="TipsDialog" parent="@android:Theme.Dialog">
        <item name="android:windowFrame">@null</item>
        <item name="android:windowFullscreen">true</item>
        <item name="android:windowNoTitle">true</item>
        <item name="android:windowIsTranslucent">false</item> 
        <item name="android:windowBackground">@null</item>
        <item name="android:windowIsFloating">true</item>
        <item name="android:windowContentOverlay">@null</item>
    </style>

  <style name="myDialogTheme" parent="android:Theme.Dialog">
        <item name="android:windowFrame">@null</item>
        <item name="android:windowIsFloating">true</item>
        <item name="android:windowIsTranslucent">false</item> 
        <item name="android:windowNoTitle">true</item><!--除去title-->
        <item name="android:windowContentOverlay">@null</item> 
        <item name="android:backgroundDimEnabled">false</item>
        <item name="android:windowBackground">@null</item><!--除去背景色-->

一般我们将一些公共属性抽象出来做为一个个style,在xml中直接引用style即可，既减少了代码而且在style发生变化的时候一处改变所引用的地方均变化

    <style name="layout_match_parent">
        <item name="android:layout_width">match_parent</item>
        <item name="android:layout_height">match_parent</item>
    </style>

    <style name="layout_wrap_content">
        <item name="android:layout_width">wrap_content</item>
        <item name="android:layout_height">wrap_content</item>
    </style>

    <style name="layout_weight_horizontal">
        <item name="android:layout_width">0dip</item>
        <item name="android:layout_height">match_parent</item>
    </style>

    <style name="layout_weight_vertical">
        <item name="android:layout_width">match_parent</item>
        <item name="android:layout_height">0dip</item>
    </style>

具体使用方式：例如我们需要自定义一个dialog,不需要dialog的title代码如下：

/**
 * 图片放大dialog
 * 
 * @author jone
 * 
 *         2014年5月13日 com.tiza.tree.xingchang_line.widget
 * 
 */
public class ImageDialog extends Dialog implements
		android.view.View.OnClickListener {

	public ImageDialog(Context context, int theme) {
		super(context, theme);
	}

	ImageView imageView;
	Button repeatButton;
	Button cancleButton;
	View rootView;
	LayoutInflater inflater;

	public static final int POSITIVE = 1;

	public static final int NEGATIVE = 2;

	public ImageDialog(Context context) {
		//调用自定义的style,用来去掉dialog默认的title
		this(context, R.style.MyDialog);
		inflater = LayoutInflater.from(context);
		init();
		wm = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);
		dm = new DisplayMetrics();
		wm.getDefaultDisplay().getMetrics(dm);
		screenWidth = dm.widthPixels;
		screenHeight = dm.heightPixels;
		Log.i("tag", screenHeight+":"+screenHeight);
	}

	public Button getRightButton(){
		return repeatButton;
	}
	
	private void init() {
		rootView = inflater.inflate(R.layout.xc_img_dialog, null);
		setContentView(rootView);
		imageView = (ImageView) rootView.findViewById(R.id.xc_big_img_);
		repeatButton = (Button) rootView.findViewById(R.id.xc_big_left);
		cancleButton = (Button) rootView.findViewById(R.id.xc_big_right);
		repeatButton.setOnClickListener(this);
		cancleButton.setOnClickListener(this);
	}

	public void setImageView(BitmapDrawable drawable) {
		imageView.setImageDrawable(drawable);
	}

	public void setDialogLayoutParamtrs(){
		LayoutParams params = new LayoutParams(screenWidth-20, screenHeight-200);
		params.setMargins(10, 25, 10, 10);
		imageView.setLayoutParams(params);
	}

	public interface ImageListener {
		public void onButtonClick(int id);
	}

	public ImageListener listener;
	private DisplayMetrics dm;
	private WindowManager wm;
	private int screenWidth;
	private int screenHeight;

	public void setImageListener(ImageListener listener) {
		this.listener = listener;
	}

	@Override
	public void onClick(View v) {

		switch (v.getId()) {
		case R.id.xc_big_left:
			if (listener != null) {
				listener.onButtonClick(POSITIVE);
			}
			break;
		case R.id.xc_big_right:
			if (listener != null) {
				listener.onButtonClick(NEGATIVE);
			}
			break;
		default:
			break;
		}
	}
