Android loading Dialog 自定義

                看到IOS端做了這個加載數據的效果,爲了保持UI一致,就自定義了Loading Dialog ! 


先看一下大概的效果:



下面就是代碼部分:

   res/drawable/

        

<?xml version="1.0" encoding="utf-8"?>
<rotate xmlns:android="http://schemas.android.com/apk/res/android"
    android:fromDegrees="0"
    android:pivotX="50%"
    android:pivotY="50%"
    android:toDegrees="360" >
    <shape
        android:innerRadiusRatio="3"
        android:shape="ring"
        android:thicknessRatio="20"
        android:useLevel="false"
        >

        <gradient
            android:centerColor="@color/colorAccent" // 主題控件顏色,可以根據需要給定
            android:centerY="0.50"
            android:endColor="@color/colorAccent"
            android:startColor="#00ffffff"
            android:type="sweep"
            android:useLevel="false" />
    </shape>

</rotate>

 Dialog主要佈局:

       layout/ 

        

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/ll_dialog"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingTop="15dp"
    android:paddingRight="25dp"
    android:paddingLeft="25dp"
    android:paddingBottom="5dp"
    android:gravity="center">

   

    <ProgressBar
        android:id="@+id/pb_progress_bar"
        android:layout_width="50dp"
        android:layout_height="50dp"
        android:indeterminateDrawable="@drawable/progressbar"
        android:indeterminateDuration="700"
        android:visibility="visible"
        />

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_margin="7dp"
        android:text="New Text"
        android:id="@+id/tv_loading"
        android:layout_gravity="center_horizontal" />
</LinearLayout>

   主要代碼部分:

        java:

         

/**
 *
 * @param context
 * @param isAlpha 是否需要透明度
 * @param message 顯示加載的內容
 * @return
 */
public static Dialog writeDialog(Context context,boolean isAlpha,String message){
    Dialog progressDialog = new Dialog(context);
    progressDialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
    if (isAlpha){
        WindowManager.LayoutParams lp= progressDialog.getWindow().getAttributes();
        lp.alpha=0.8f;
        progressDialog.getWindow().setAttributes(lp);
    }
    LayoutInflater inflater = LayoutInflater.from(context);
    View v = inflater.inflate(R.layout.dialog, null);
    LinearLayout layout = (LinearLayout) v.findViewById(R.id.ll_dialog);
    ProgressBar pb_progress_bar = (ProgressBar) v.findViewById(R.id.pb_progress_bar);
    pb_progress_bar.setVisibility(View.VISIBLE);

    TextView tv  = (TextView) v.findViewById(R.id.tv_loading);

    if (message==null||message.equals("")){
        tv.setVisibility(View.GONE);
    }else{
        tv.setText(message);
        //R.color.colorAccent 我是拿的主題控件顏色,可以根據需要給
  tv.setTextColor(context.getResources().getColor(R.color.colorAccent)); } progressDialog.setContentView(layout, new LinearLayout.LayoutParams( LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.MATCH_PARENT)); return progressDialog;}

Activity:

    java:

    progressDialog = DialogUtil.writeDialog(this,false,"正在加載");
    progressDialog.show();
    progressDialog.setCanceledOnTouchOutside(false);//設置點擊屏幕加載框不會取消(返回鍵可以取消)
