设置自定义的Dialog的大小不管用？？？

[Jack---Jiao]

activity中

share = (Button) findViewById(R.id.shareBtn);
		share.setOnClickListener(new OnClickListener() {

			@Override
			public void onClick(View arg0) {
				// TODO Auto-generated method stub
				//初始化一个自定义的Dialog
                Dialog dialog = new ShareDialog(CartoonActivity.this,  R.style.ShareDialog);
                /*
                 * 将对话框的大小按屏幕大小的百分比设置
                 */
                WindowManager.LayoutParams params =dialog.getWindow().getAttributes();  // 获取对话框当前的参数值        
                params.height = (int) (ConstantApplication.getInstance().getScreenHeight());
                params.width = (int) (ConstantApplication.getInstance().getScreenWidth());
                dialog.getWindow().setAttributes(params);
                dialog.show();
			}
		});

这是自定义dialog类

public class ShareDialog extends Dialog {
	Context context;

	public ShareDialog(Context context) {
		super(context);
		// TODO Auto-generated constructor stub
		this.context = context;
	}

	public ShareDialog(Context context, int theme) {
		super(context, theme);
		this.context = context;
	}

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		// TODO Auto-generated method stub
		super.onCreate(savedInstanceState);
		this.setContentView(R.layout.share_dialog);
	}

}

这是自定义dialog样式

 <style name="ShareDialog" parent="@android:Theme.Dialog">
        <item name="android:windowFrame">@null</item>   <!--边框-->
        <item name="android:windowNoTitle">true</item> 
        <item name="android:windowBackground">@drawable/share_dialog_bg</item>
        <item name="android:windowIsFloating">true</item>
        <item name="android:windowContentOverlay">@null</item>
    </style>

dialog 的onCreateDialog里设置： dialog.setContentView(layoutview,params); layoutview 是绑定了你要加载的dialog 的布局
