每個活動中的常見進度條Android

Question

我已經修改瞭解決方案。我能夠得到進度條，但進度條永遠不會隱藏

這裏是類創建相對佈局的進度條

public class ProgressBarHandler { 
    private ProgressBar mProgressBar; 
    private Context mContext; 
    private View _baseView; 
    private View _hideView; 
    public ProgressBarHandler(Context context,View baseView, View hideView) { 
     mContext = context; 
     _baseView = baseView; 
     _hideView = hideView; 

     ViewGroup layout = (ViewGroup) _baseView;//((Activity) context).findViewById(android.R.id.content).getRootView(); 

     mProgressBar = new ProgressBar(context, null, android.R.attr.progressBarStyleLarge); 
     mProgressBar.setIndeterminate(true); 

     RelativeLayout.LayoutParams params = new 
       RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.MATCH_PARENT); 

     RelativeLayout rl = new RelativeLayout(context); 

     rl.setGravity(Gravity.CENTER); 
     rl.addView(mProgressBar); 

     layout.addView(rl, params); 

     hide(); 
    } 

    public void show() { 
     mProgressBar.setVisibility(View.VISIBLE); 
     _hideView.setVisibility(View.INVISIBLE); 
    } 

    public void hide() { 
     mProgressBar.setVisibility(View.INVISIBLE); 
     _hideView.setVisibility(View.VISIBLE); 
    } 
} 

這是我的xml文件

這裏是活動類調用進度條

public class ProfileActivity extends AppCompatActivity { 

    FrameLayout profile_root_layout; 
    CoordinatorLayout layot_to_hide; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_profile); 
     profile_root_layout = (FrameLayout) findViewById(R.id.profile_activity); 
     layot_to_hide = (CoordinatorLayout) findViewById(R.id.layout_to_hide); 
     new userProfileTask().execute(); 
    } 




    public class userProfileTask extends AsyncTask<Void, Void, Boolean> { 
     @Override 
     protected void onPreExecute() { 
      new ProgressBarHandler(getBaseContext(),profile_root_layout,layot_to_hide).show(); 
      super.onPreExecute(); 
     } 

     @Override 
     protected Boolean doInBackground(Void... params) { 
      try { 
       Thread.sleep(2000); 

      } catch (InterruptedException e) { 
       e.printStackTrace(); 
      } 

      return null; 
     } 

     @Override 
     protected void onPostExecute(Boolean aBoolean) { 

      new ProgressBarHandler(getBaseContext(),profile_root_layout,layot_to_hide).hide(); 
     } 
    } 

} 

進度條永遠不會hides.Whe我正在犯錯誤。

Answer 1

然後做一個單獨的類使與該參數的靜態方法就可以了參數包含活動......呼籲烏爾活動這種方法，並在其中

Answer 2

它非常簡單，你可以在做傳遞活動名稱多種方式。 1）您可以定義基本活動並編寫進度對話框的代碼，並從BaseActivity中使用Progressdialog擴展所有活動。 2）你可以有自定義的單獨的類，並在所有活動中使用。 等

這裏是一個很好的例子，你可以像這個例子一樣修改你的代碼。 ProgressHud

或者也使用它。

Answer 3

我建議創建一個對話框，並在活動課這樣調用

dialog = new Dialog(getActivity(), android.R.style.Theme_Black); 
    View views = LayoutInflater.from(getActivity()).inflate(R.layout.activity_dialog, null); 
    dialog.requestWindowFeature(Window.FEATURE_NO_TITLE); 
    dialog.getWindow().setBackgroundDrawableResource(R.color.feed_item_bg); 
    dialog.setContentView(views); 
    dialog.show(); 

，並在你的異步任務onPostExecute駁回對話框

dialog.dismiss(); 

Answer 4

public static void getProgress(Activity activity,FrameLayout relativeLayout){ 
final ProgressBar pb; 
int progressStatus = 0; 
final Handler handler = new Handler(); 
pb = new ProgressBar(activity, null, android.R.attr.progressBarStyleHorizontal); 
LayoutParams lp = new LayoutParams(550,LayoutParams.WRAP_CONTENT); 
pb.setLayoutParams(lp); 
LayoutParams params = (LayoutParams) pb.getLayoutParams(); 
pb.setLayoutParams(params); 
pb.getProgressDrawable().setColorFilter(Color.BLUE, PorterDuff.Mode.SRC_IN); 
relativeLayout.addView(pb); 
new Thread(new Runnable() { 
@Override 
public void run() { 
int progressStatus = 0; 
while(progressStatus < 100){ 
progressStatus +=1; 
try{ 
Thread.sleep(20); 
}catch(InterruptedException e){ 
e.printStackTrace(); 
} 
final int finalProgressStatus = progressStatus; 
handler.post(new Runnable() { 
@Override 
public void run() { 
pb.setProgress(finalProgressStatus); 
} 
}); 
} 
} 
}).start(); // Start the operation 
}
