在表视图中添加布局
我在xml中创建了一个代码，使用tablerow创建了一个tablelayou，每个tablerow都有3个线性布局。 第一个线性布局的宽度= 40dp，高度= 90dp。第二个linearlayout的宽度= 0dp，高度= 90dp，权重= 1，第三个linearlayout等于de first。所以我有这个结果：
所以我需要在java上创建相同的布局，我使用相同的配置但是对齐很糟糕。我该怎么做呢？看，
我把边框显示对齐。这是java代码：
int wlienar = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 40, getResources().getDisplayMetrics());
int hlienar = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 90, getResources().getDisplayMetrics());
int wLienarUserDataBeer = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 0, getResources().getDisplayMetrics());
int hLienarUserDataBeer = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 90, getResources().getDisplayMetrics());
int wUserPicture = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 40, getResources().getDisplayMetrics());
int hUserPicture = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 40, getResources().getDisplayMetrics());
int wLogoBeer = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 40, getResources().getDisplayMetrics());
int hLogoBeer = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 40, getResources().getDisplayMetrics());
int margim = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 5, getResources().getDisplayMetrics());
Bitmap bmImage = BitmapFactory.decodeResource(getResources(),R.mipmap.eu);
iconViewRound.setImageBitmap(bmIcon);
imageViewRound.setImageBitmap(bmImage);
/* Find Tablelayout defined in main.xml */
TableLayout tl = (TableLayout) findViewById(R.id.feeds_table);
GradientDrawable border = new GradientDrawable();
border.setColor(0xFFFFFFFF); //white background
border.setStroke(1, 0xFF000000); //black border with full opacity
for(int i=0 ; i < 10 ; i++) {
/*create a linear layout to user picture*/
LinearLayout linearUserPicture = new LinearLayout(this);
linearUserPicture.setOrientation(LinearLayout.VERTICAL);
linearUserPicture.setBackground(border);
LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(wlienar, hlienar);
layoutParams.setMargins(0, 0, margim, 0);
// layoutParams.gravity = Gravity.NO_GRAVITY;
RoundedImageView imageView = new RoundedImageView(this, null);
imageView.setImageResource(R.mipmap.eu);
//setting image position
imageView.setLayoutParams(new ViewGroup.MarginLayoutParams(wUserPicture, hUserPicture));
linearUserPicture.addView(imageView, layoutParams);

答案 0 :(得分：0)
您需要向LienarLayout提供LayoutParams。将layout_width设置为match_parent，它将填充单元格的中间部分。但是还有一个问题：TextViews应该推送LinearLayout，但它们不会。问题是您正在构建没有属性的所有这些视图。例如，TextView有几个构造函数。对于代码实例化，您应该使用
TextView myTextView = new TextView(context, attributeSet);
其中attributeSet是AttributeSet（http://developer.android.com/reference/android/util/AttributeSet.html）。这将允许您以与在xml中相同的方式操作TextView。到目前为止，他们可能都有默认宽度，不剪辑其内容，所以一切都很好。通过使用attributeSet，您也可以控制textviews宽度。
EDIT :: 我发现我错了，你在调用addView（）时提供了LayoutParams。
在这一行：
LinearLayout.LayoutParams layoutParamsUserDataBeer = new LinearLayout.LayoutParams(0, hLienarUserDataBeer,1);
将宽度设置为0，将权重设置为1，这与其他布局设置为WRAP_CONTENT的事实冲突。 请尝试改为：
LinearLayout.LayoutParams layoutParamsUserDataBeer = new LinearLayout.LayoutParams(ViewGroup.MATCH_PARENT, hLienarUserDataBeer,0);

在katzenhut和我的朋友Afonso的帮助下
在我的tablerow中我有3列，所以第一列是数字0，第二列是数字1，第三列是数字2，就像一个列从0开始的数组。所以默认情况下，表格布局中的列是WRAP_CONTENT ，在表格布局中应该设置为MATCH_PARENT的列，在我的情况下第二列是MATCH_PARENT，所以我添加这一行：
tl.setColumnStretchable( 1, true );
对齐保持良好，完整代码：
TableLayout tl = (TableLayout) findViewById(R.id.feeds_table);
tl.setColumnStretchable( 1, true ); // this line fix the error
for(int i=0 ; i < 10 ; i++) {
