android 自定义Dialog页面加载中效果的进度条 Dialog 边角 Dialog 棱角

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dialog
loadingDialog.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...
