TableLayOut の動的な作成に問題があるのは、私が初めてではないようです。問題は、TableRow オブジェクトを TableLayout に追加すると、Android アプリケーションがクラッシュし、予期しないエラーで終了することです。
私がしたいこと？次のアイテムのレイアウトでダイアログを作成したい
-------------------
|Custom |____|____| <-- Something like property grid
|graphic|____|____|
|view |____|____|
| |____|____|
-------------------
閉じるボタン
それを行うために、私は次の方法を使用しています。
1. DialogLayout クラスの作成
2. Dialog クラスの作成
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);
}
}
Dialog class :
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()!!!
}
}
アプリケーションクラッシュの次の理由を確認しました
- 私のカスタムビューは大丈夫ですか？- はい、大丈夫です。アプリケーションの動作には何の影響もありません
他に理由がある場合は？- はい。奇妙なことに、アプリは に入れようとしているときにのみクラッシュ
m_row0しm_layoutます。しかし、コード行にコメントしているときm_layout.addView(m_row0, new TableLayout. LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
すべてが正常に機能し始めますが、テーブルはありません。
よろしくお願いします。
