使进度条透明背景

我使用this library作为进度指示器，而我通过网络服务完成后台工作。我想在进度条显示时让背景透明。有没有什么方法可以使窗口透明编程，就像使用进度对话框一样？使进度条透明背景

public class MainActivity extends AppCompatActivity{ 
 

 
    private EditText email, pass; 
 
    private SessionManager session; 
 
    private SQLiteHandler db; 
 
    private AVLoadingIndicatorView pb; 
 
    private static final String LOGIN = "http://ubooktoday.com/android/login"; 
 

 
    @Override 
 
    protected void onCreate(Bundle savedInstanceState) { 
 
     super.onCreate(savedInstanceState); 
 
     setContentView(R.layout.activity_main); 
 
     
 
     email = (EditText)findViewById(R.id.et1); 
 
     pass = (EditText)findViewById(R.id.et2); 
 

 
     session = new SessionManager(getApplicationContext()); 
 
     db = new SQLiteHandler(getApplicationContext()); 
 
     pb = new AVLoadingIndicatorView(this); 
 

 
     if (session.isLoggedIn()) { 
 
      startActivity(new Intent(MainActivity.this, ListVActivity.class)); 
 
      finish(); 
 
     } 
 
    } 
 
    
 
    public void login(View view){ 
 

 
     if (!email.getText().toString().equals("") && !pass.getText().toString().equals("")) { 
 
      loginRequest(); 
 
     }else{ 
 
      Toast.makeText(getApplicationContext(), "Please enter the details", Toast.LENGTH_SHORT).show(); 
 
     } 
 
     
 

 
    } 
 

 
    private void loginRequest() { 
 

 
     startAnim(); 
 

 
     StringRequest stringRequest = new StringRequest(Request.Method.POST, LOGIN, 
 
       new Response.Listener<String>() { 
 
        @Override 
 
        public void onResponse(String response) { 
 

 
         stopAnim(); 
 

 
         try { 
 
          JSONObject jObj = new JSONObject(response); 
 

 
          String status = jObj.getString("status"); 
 

 
          // Now check status value 
 
          if (status.equals("0")) { 
 

 
           Toast.makeText(getApplicationContext(), jObj.getString("message"), Toast.LENGTH_LONG).show(); 
 
          } else if (status.equals("1")) { 
 

 
           session.setLogin(true); 
 
           db.addUser(jObj.getString("spa_name"), jObj.getString("user_id")); 
 

 
           startActivity(new Intent(MainActivity.this, ListVActivity.class)); 
 
           finish(); 
 

 

 

 
          } 
 
         } catch (JSONException e) { 
 
          // JSON error 
 
          e.printStackTrace(); 
 
          Toast.makeText(getApplicationContext(), "Json error: " + e.getMessage(), Toast.LENGTH_LONG).show(); 
 
         } 
 
        } 
 
       }, new Response.ErrorListener() { 
 
      @Override 
 
      public void onErrorResponse(VolleyError error) { 
 
       Toast.makeText(getApplicationContext(), "VolleyError" + error.toString(), Toast.LENGTH_LONG).show(); 
 
      } 
 
     }) { 
 
      @Override 
 
      protected Map<String, String> getParams() { 
 
       Map<String, String> params = new HashMap<String, String>(); 
 
       params.put("email", email.getText().toString()); 
 
       params.put("pass", pass.getText().toString()); 
 
       return params; 
 
      } 
 

 
     }; 
 

 
     RequestQueue requestQueue = Volley.newRequestQueue(getApplicationContext()); 
 
     requestQueue.add(stringRequest); 
 
    } 
 

 
    public void startAnim(){ 
 
     findViewById(R.id.avloadingIndicatorView).setVisibility(View.VISIBLE); 
 
     
 
    } 
 

 
    public void stopAnim(){ 
 
     findViewById(R.id.avloadingIndicatorView).setVisibility(View.GONE); 
 
     
 
    } 
 
}

试试这个。创建自定义对话框类

public class CShowProgress { 
public static CShowProgress mCShowProgress; 
public Dialog mDialog; 

public CShowProgress() { 
} 

public static CShowProgress getInstance() { 
    if (mCShowProgress== null) { 
     mCShowProgress= new CShowProgress(); 
    } 
    return mCShowProgress; 
} 

public void showProgress(Context mContext) { 
    mDialog= new Dialog(mContext); 
    mDialog.requestWindowFeature(Window.FEATURE_NO_TITLE); 
    mDialog.setContentView(R.layout.custom_progress_layout); 
    mDialog.findViewById(R.id.progress_bar).setVisibility(View.VISIBLE); 
    mDialog.getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT)); 
    mDialog.setCancelable(true); 
    mDialog.setCanceledOnTouchOutside(true); 
    mDialog.show(); 
} 

public void hideProgress() { 
    if (mDialog!= null) { 
     mDialog.dismiss(); 
     mDialog= null; 
    } 
    } 
}

相应的XML custom_progress_layout.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    xmlns:app="http://schemas.android.com/apk/res-auto" 
    android:background="@android:color/transparent" 
    android:orientation="vertical"> 

    <com.wang.avi.AVLoadingIndicatorView 
    android:id="@+id/progress_bar" 
    app:indicator="SemiCircleSpin" 
    app:indicator_color="@android:color/black" 
    android:layout_width="50dp" 
    android:layout_height="50dp" 
    android:visibility="visible" /> 
</RelativeLayout>

以及活动

CShowProgress cShowProgress = CShowProgress.getInstance(); 
    cShowProgress.showProgress(Activity.this);

，并通过调用

cShowProgress.hideProgress();

隐藏

希望这会有所帮助。

它确实有效！谢啦。 –

快乐的编码咩:) :) @SomnathPal – Sanoop

@Sanoop请：我已经尝试了很多方式与这个库，但动画不开始，图像显示静态。可能这与我的线性布局有关系吗？非常感谢你，并感到很抱歉。 – statosdotcom

试试这个方法：

ProgressDialog pd = new ProgressDialog(Login.this,R.style.MyProgressTheme); 
pd.setCancelable(false); 
pd.setProgressStyle(android.R.style.Widget_ProgressBar_Small); 
pd.show();

，创造主题价值观\ styles.xml

<style name="MyProgressTheme" parent="android:Theme.Holo.Dialog"> 
    <item name="android:alertDialogStyle">@style/MyDialogStyle</item> 
    <item name="android:windowBackground">@color/transparent</item> 
    <item name="android:textColorPrimary">#FFFFFF</item> 
    <item name="android:backgroundDimEnabled">false</item> 
    <item name="android:textColor">#FFFFFF</item> 
    <item name="android:textStyle">normal</item> 
    <item name="android:textSize">12sp</item> 
</style>

，并添加这个主题价值观\ styles.xml

<style name="MyDialogStyle"> 
    <item name="android:bottomBright">@color/transparent</item> 
    <item name="android:bottomDark">@color/transparent</item> 
    <item name="android:bottomMedium">@color/transparent</item> 
    <item name="android:centerBright">@color/transparent</item> 
    <item name="android:centerDark">@color/transparent</item> 
    <item name="android:centerMedium">@color/transparent</item> 
    <item name="android:fullBright">@color/transparent</item> 
    <item name="android:fullDark">@color/transparent</item> 
    <item name="android:topBright">@color/transparent</item> 
    <item name="android:topDark">@color/transparent</item> 
</style>

并添加值\ colors.xml

<color name="transparent">#00000000</color>

编辑1

<com.wang.avi.AVLoadingIndicatorView 
    android:id="@+id/avloadingIndicatorView" 
    android:layout_width="wrap_content" //or your custom size 
    android:layout_height="wrap_content" //or your custom size 
    android:visibility="visible" //visible or gone 
    app:indicator="BallPulse" 
    app:indicator_color="your color" 
    android:background="@android:color/transparent" 
    />

这种力量帮助你。

我想要有相同的进度条库，而不是使用进度对话框。可能吗？ @Sathish –

试试我编辑的答案 –

它不能正常工作 –
