似乎我不是第一个动态创建TableLayOut的人.问题是,当我将TableRow对象添加到TableLayout时,我的android应用程序崩溃并完成了意外错误.
我想做的事？
我想用下一个项目布局创建对话框
-------------------
|Custom |____|____| <-- Something like property grid
|graphic|____|____|
|view |____|____|
| |____|____|
-------------------
关闭按钮
为了做到这一点,我正在使用下一个方法.
1.创建DialogLayout类
2.创建Dialog类
public class DialogLayout extends LinearLayout
{
private CustomView m_view;
private TableLayout m_layout;
private TableRow m_row0;
private TextView m_propName;
private EditText m_propValue;
public DialogLayout(Context context)
{
super(context);
Init(context);
}
private void Init(Context context)
{
setOrientation(LinearLayout.HORIZONTAL);
m_layout = new TableLayout(context);
m_layout.setLayoutParams(new TableLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
m_layout.setStretchAllColumns(true);
m_propName= new TextView(context);
m_propName.setText("PropName:");
m_propValue = new EditText(context);
m_propValue.setText("--");
m_row0 = new TableRow(context);
m_row0.addView(m_propName);
m_row0.addView(m_propValue);
m_layout.addView(m_row0, new TableLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
m_view= new CustomView(context);
int h = (int) Math.min(m_layout.getHeight(), 600);
if (h < 600)
h = 600;
LinearLayout.LayoutParams adapt = new LayoutParams(300, h);
m_view.setLayoutParams(adapt);
addView(m_view);
addView(m_layout);
setFocusable(true);
setFocusableInTouchMode(true);
}
}
对话类：
public class Dialog
{
private Builder m_dialog = null;
private DialogLayout m_layout = null;
public Dialog(Context context)
{
m_layout = new DialogLayout(context);
m_dialog = new AlertDialog.Builder(context);
m_dialog.setTitle("My dialog");
m_dialog.setView(m_layout);
m_dialog.setNegativeButton("Close button", null);
}
public void show()
{
m_dialog.show(); // Seems to be it does not correctly calls m_dialog.show()!!!
}
}
我检查了应用程序崩溃的下一个原因
>如果我的自定义视图没问题？ – 是的,没关系.它对应用程序行为没有任何影响
>如果还有其他原因？ – 是的这很奇怪,但只有当我试图将m_row0放入m_layout时app才会崩溃.但是当我在评论代码行时
m_layout.addView(m_row0,新的TableLayout.
LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT));
一切都开始正常,但没有桌子.
预先感谢您的任何帮助.

解决方法:
您应该使用TableRow.LayoutParams而不是TableLayout.LayoutParams.
