Question

我正在尝试对包含一些textView的布局进行扩充。当我将它添加到tableRow时，该布局中的textViews会重叠。换句话说，我猜想layout_width和layout_height被忽略了。

但是当我在充气后添加rowView.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT));时，什么都没有出现。

TableRow tableRow = new TableRow(this);
TableRow.LayoutParams lp = new TableRow.LayoutParams(TableRow.LayoutParams.MATCH_PARENT, TableRow.LayoutParams.WRAP_CONTENT);
tableRow.setLayoutParams(lp);

View rowView = getLayoutInflater().inflate(R.layout.layout_result_row, null);
rowView.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT));
loadResultRow(rowView, result); //This method sets the text of the textViews
tableRow.addView(rowView);
tableLayout.addView(tableRow);

Answer 1

膨胀的布局已经有了布局参数，所有的chid视图都没有使用新的布局参数重绘。如果您希望在充气后获得与之前相同的视图，则可以使用以下代码。

 TableLayout tableLayout = new TableLayout(getApplicationContext());
    tableLayout.setBackgroundColor(Color.RED);
    TableRow tableRow = new TableRow(this);
    TableRow.LayoutParams lp = new 
   TableRow.LayoutParams(TableRow.LayoutParams.MATCH_PARENT,TableRow.LayoutParams.WRAP_CONTENT);
    tableRow.setLayoutParams(lp);

    View rowView = getLayoutInflater().inflate(R.layout.activity_main, null);
    tableLayout.setStretchAllColumns(true);
   // rowView.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT));
   // loadResultRow(rowView, result); //This method sets the text of the textViews
    tableRow.addView(rowView);
    tableLayout.addView(tableRow);
    setContentView(tableLayout);

Answer 2

而不是：

TableRow.LayoutParams lp = new TableRow.LayoutParams(
                   TableRow.LayoutParams.MATCH_PARENT, TableRow.LayoutParams.WRAP_CONTENT);

尝试：

TableLayout.LayoutParams lp = new TableLayout.LayoutParams(
             TableLayout.LayoutParams.MATCH_PARENT, TableLayout.LayoutParams.WRAP_CONTENT);

将夸张的布局儿童添加到TableRow时，它们会相互重叠
