android 动态生成tablelayout 动态tablelayout创建的android应用程序崩溃

时间：2023-03-24 21:27:02

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 |____|____|

|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.
