android布局和布局参数

android线性布局：

    myLinearLayout = new LinearLayout(this); 

    myLinearLayout.setOrientation(LinearLayout.VERTICAL);

    myLinearLayout.setBackgroundColor(android.graphics.Color.WHITE);

LinearLayout布局参数：

    LinearLayout.LayoutParams param1 = new LinearLayout.LayoutParams(

         LinearLayout.LayoutParams.FILL_PARENT,

        LinearLayout.LayoutParams.WRAP_CONTENT);

    myTextView = new TextView(this);

    myTextView.setText(R.string.title);
    myTextView.setTextColor(getResources().getColor(R.drawable.blue));

//使用布局参数，添加控件

    myLinearLayout.addView(myTextView, param1);

//如果控件已经添加了

    LinearLayout.LayoutParams linearParams = (LinearLayout.LayoutParams) content.getLayoutParams();
        linearParams.height = (int) (dm.heightPixels*0.89);
        imageview.setLayoutParams(linearParams);
