如何设置自定义布局以进入对话框背景？

Question

标题中的问题)请帮助我)我想从中做出这个

那

我试过实现它.

mProgressDialog = new ProgressDialog(this);
mProgressDialog.getWindow().setContentView(R.layout.footcloth);
mProgressDialog.setMessage(Constants.PROGRESS_DIALOG_MESSAGE);
mProgressDialog.show();

但是这个代码抛出异常

java.lang.RuntimeException: Unable to start activity ComponentInfo{im.anticafe.anticafeim/im.anticafe.anticafeim.activities.HomeActivity}: android.util.AndroidRuntimeException: requestFeature() must be called before adding content

此代码在活动BottomBarActivity中实现

abstract public class BottomBarActivity extends AppCompatActivity implements View.OnClickListener {

    private static final String TAG = "bottomBarActivity";
    private int mWidth;
    private ProgressDialog mProgressDialog;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        ...
        mProgressDialog = new ProgressDialog(this);
        mProgressDialog.getWindow().setContentView(R.layout.footcloth);
        mProgressDialog.setMessage(Constants.PROGRESS_DIALOG_MESSAGE);
        mProgressDialog.show();
        ...
    }

    ...
}

而这项活动正在其他方面扩展.所以,请帮我解决我的问题,谢谢)

有2个答案

1. 如果您想在"进度"对话框中更改背景的颜色(透明度),我建议您使用片段并切换它们.在片段中,您可以设置任何属性并放入ProgressBar

完成重新加载后,您可以再次切换回或另一个片段

2. 如果你想改变进度对话框

   public class TransparentProgressDialog extends Dialog {
   
     public TransparentProgressDialog(Context context) {
       super(context, R.style.TransparentProgressDialog);
   
       WindowManager.LayoutParams wlmp = getWindow().getAttributes();
   
       wlmp.gravity = Gravity.CENTER_HORIZONTAL;
       getWindow().setAttributes(wlmp);
       setTitle(null);
       setCancelable(false);
       setOnCancelListener(null);
       View view = LayoutInflater.from(context).inflate(
               R.layout.progress_dialog, null);
       setContentView(view);
      }
   }
   

在你的活动中使用

TransparentProgressDialog pd = new TransparentProgressDialog(context);
pd.show();

....

if (pd.isShowing()){
            pd.dismiss();
        }
