我创建了一系列按钮.现在我想找到按钮的高度和宽度,为此我使用了getWidth()和getHeight().但问题是它总是返回0.为什么会发生这种情况?我发送了我的代码,请检查是否有任何问题.
int x,y;
LinearLayout layoutVertical = (LinearLayout) findViewById(R.id.liVLayout);
LinearLayout rowLayout = null;
LayoutParams param = new LinearLayout.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT, 1);
//Create Button
for (int i = 0; i<6; i++)
{
rowLayout = new LinearLayout(this);
rowLayout.setWeightSum(7);
layoutVertical.addView(rowLayout, param);
for(int j=0; j<7; j++)
{
m_pBtnDay[i][j] = new Button(this);
rowLayout.addView(m_pBtnDay[i][j], param);
m_pBtnDay[i][j].setOnLongClickListener(this);
m_pBtnDay[i][j].setGravity(Gravity.CENTER_HORIZONTAL | Gravity.CENTER_VERTICAL);
m_pBtnDay[i][j].setTextSize(12);
}
}
x = m_pBtnDay[i][j].getWidth();
y = m_pBtnDay[i][j].getHeight();
Log.d("width", Integer.toString(x));
Log.d("Height", Integer.toString(y));
return true;
