Question

我的应用使用以编程方式生成的TableLayouts显示在RelativeLayout上方。 TableLayout中的第一行包括一个分配了onClickListener的TextView。 TableLayouts使用TranslateAnimation显示在屏幕的BOTTOM上。令人费解的是，正在听到咔嗒声，但只是在ActionBar正下方的屏幕顶部。另外只有一个听众正在开火。我必须承认我对此感到困惑。我以为使用android:descendantFocusability="blocksDescendants">会解决它，但没有这样的运气。在将设计转换为ListView之前（我不想这样做）我希望StackOverflow专家可以帮助解决这个问题。

以下是显示2个生成的TableLayouts的屏幕截图： screenshot

这是RelativeLayout父级：

<View

这是生成可点击按钮的代码。 Button位于该行的第二列。图像位于第一列

    // Add NAME to 1st row 
      watchAreaName[overlayNumber] = new Button(this); // findViewById(R.id.WatchArea_Name);
      watchAreaName[overlayNumber].setText("\"" + ControlPanel.pWatchAreaName[GPS_unit_selected][iWatch] + "\" Watch Activity");
      watchAreaName[overlayNumber].setPadding(1, 1, 1, 1); // left, top, right, bottom
      watchAreaName[overlayNumber].setTextSize(HEADER_ROW1_TEXT_SIZE);
      watchAreaName[overlayNumber].setTextColor(Color.WHITE); // deep blue=parseColor("#00297C")
      watchAreaName[overlayNumber].setTypeface(null, Typeface.BOLD);
      watchAreaName[overlayNumber].setGravity(Gravity.CENTER); // (Gravity.CENTER_VERTICAL | Gravity.LEFT)
      watchAreaName[overlayNumber].setFocusable(false); 
      watchAreaName[overlayNumber].setId(GPSTrackerOverlayLayout_ids[overlayNumber]);  //set ID equivalent to parent
      watchAreaName[overlayNumber].setTag(iWatch+ "=|"+ControlPanel.pWatchAreaName[GPS_unit_selected][iWatch]+ "|");

  // Add to parent TableRow, then set LayoutParams
    headerRow[overlayNumber].addView(watchAreaName[overlayNumber]);
    TableRow.LayoutParams watchAreaName_layout_params = (TableRow.LayoutParams) watchAreaName[overlayNumber].getLayoutParams();
    watchAreaName_layout_params.column = SECOND_COLUMN; // place in 2nd column
    watchAreaName_layout_params.height = HEADER_ROW1_HEIGHT; // TableRow.LayoutParams.WRAP_CONTENT;
    watchAreaName_layout_params.width = 0;  //COLUMN_LABELS_WIDTH;
    watchAreaName_layout_params.weight = (float) .85;
    watchAreaName_layout_params.span = 1; // span this many columns (optional)
    watchAreaName[overlayNumber].setLayoutParams(watchAreaName_layout_params); // 
    watchAreaName[overlayNumber].setBackgroundColor(watchAreaColorIds[watchAreaBackgroundColorSelections[overlayNumber]]); 
    watchAreaName[overlayNumber].setClickable(true);
    watchAreaName[overlayNumber].setOnClickListener(new ShowHideOverlayListener());

 // add finished Header row to TableLayout parent
    GPSTrackerOverlayLayout[overlayNumber].addView(headerRow[overlayNumber], new TableLayout.LayoutParams(TABLE_MATCH_PARENT, TABLE_WRAP_CONTENT)); // width, height
    headerRow[overlayNumber].setFocusable(false);

Android：为什么只能在屏幕顶部听到点击而不是分配的视图？
