Dialog 边角 Dialog 棱角

<style name="loading_dialog" parent="android:Theme.Dialog">        <item name="android:windowFrame">@null</item>        <!-- Dialog的windowFrame框为无 -->        <item name="android:windowBackground">@color/transparent</item>        <!-- 设置dialog的背景 -->        <item name="android:windowNoTitle">true</item>        <!-- 是否显示title -->        <item name="android:windowIsTranslucent">true</item>        <!-- 是否半透明 -->        <item name="android:windowIsFloating">true</item>        <!-- 是否浮现在activity之上 -->        <item name="android:windowContentOverlay">@null</item>        <!-- 也是个drawable，定义contentoverlay的背景 -->        <item name="android:backgroundDimEnabled">false</item>        <!-- 背景是否模糊显示 -->    </style>

Dialog loadingDialog = new Dialog(context, R.style.loading_dialog); // 创建自定义样式dialogloadingDialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));

加载数据时调用的方法：

LodingDialog dialog = new LodingDialog(this);

dialog.show();// 显示加载条

dialog.dismiss();// 关闭加载进度条

LodingDialog.java

public class LodingDialog extends Dialog {    private Context context;    private ImageView imagLoading;    private Animation operatingAnim;    public LodingDialog(Context context) {        super(context, R.style.loading_dialog);        this.context = context;    }    @Override    protected void onCreate(Bundle savedInstanceState) {        // TODO Auto-generated method stub        super.onCreate(savedInstanceState);        setContentView(R.layout.loading);        imagLoading = (ImageView)findViewById(R.id.loading);        operatingAnim = AnimationUtils.loadAnimation(context, R.anim.cirle);        LinearInterpolator lin = new LinearInterpolator();        operatingAnim.setInterpolator(lin);        imagLoading.startAnimation(operatingAnim);    }    @Override    public void show() {        // TODO Auto-generated method stub        if (imagLoading != null) {            imagLoading.startAnimation(operatingAnim);        }        super.show();    }    @Override    public void dismiss() {        // TODO Auto-generated method stub        if (imagLoading != null) {            imagLoading.clearAnimation();        }        super.dismiss();    }        @Override    public boolean onTouchEvent(MotionEvent event) {        // TODO Auto-generated method stub        if (event.getAction()==MotionEvent.ACTION_MOVE) {            dismiss();            return true;        }        return super.onTouchEvent(event);    }    @Override    public boolean onKeyDown(int keyCode, KeyEvent event) {        // TODO Auto-generated method stub        if (keyCode == KeyEvent.KEYCODE_BACK && event.getRepeatCount() == 0) {            dismiss();            return true;        }        return super.onKeyDown(keyCode, event);    }}

styles.xml 样式切忌不可忘记

<style name="loading_dialog" parent="android:style/Theme.Dialog">        <item name="android:windowFrame">@null</item>        <item name="android:windowNoTitle">true</item>        <item name="android:windowBackground">@drawable/transpant_bg</item>        <item name="android:windowIsFloating">true</item>        <item name="android:windowContentOverlay">@null</item>        <item name="android:backgroundDimEnabled">false</item>    </style>

loading.xml

<?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:background="#00ffffff"    android:orientation="vertical"    android:gravity="center">   <ImageView       android:id="@+id/loading"       android:layout_width="wrap_content"       android:layout_height="wrap_content"       android:layout_centerInParent="true"       android:src="@drawable/yj_refresh"/> <!-- 就是你要的加载图片 -->   </RelativeLayout>

到此就算是dialog加载进度条就算完成了...
