android - AndroidのアラートダイアログでTextViewとEditTextのビューを設定するには?

Question

以下のコードを使用して、アラート ダイアログの TextView と EditText をテーブル レイアウトで設定します。しかし、私はUIに入りませんでした。

  LinearLayout layout1 = new LinearLayout(SimpleListViewActivity.this);
layout1.setOrientation(LinearLayout.VERTICAL);

final EditText nameEdt = new EditText(this);
final EditText nameEdt1 = new EditText(this);
final EditText nameEdt2 = new EditText(this);
final EditText nameEdt3 = new EditText(this);

LinearLayout.LayoutParams TxtLayoutParams = new LinearLayout.LayoutParams(50,50);
TableRow.LayoutParams rowparams = new TableRow.LayoutParams(LinearLayout.LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT);
LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(20, 50);
nameEdt.setLayoutParams(new ViewGroup.LayoutParams(20, 20));
nameEdt1.setLayoutParams(new ViewGroup.LayoutParams(20, 20));
nameEdt2.setLayoutParams(new ViewGroup.LayoutParams(20,20));
nameEdt3.setLayoutParams(new ViewGroup.LayoutParams(20, 20));

TextView groupTxt = new TextView(SimpleListViewActivity.this);
groupTxt.setLayoutParams(TxtLayoutParams);
groupTxt.setText("Group");
TextView clientTxt = new TextView(SimpleListViewActivity.this);
clientTxt.setLayoutParams(TxtLayoutParams);
clientTxt.setText("Client");
TextView docTxt = new TextView(SimpleListViewActivity.this);
docTxt.setLayoutParams(TxtLayoutParams);
docTxt.setText("Doc_type");
TextView nameTxt = new TextView(SimpleListViewActivity.this);
nameTxt.setLayoutParams(TxtLayoutParams);
nameTxt.setText("Name");

TableRow grouprow = new TableRow(SimpleListViewActivity.this);
grouprow.setLayoutParams(rowparams);
TableRow clientrow = new TableRow(SimpleListViewActivity.this);
clientrow.setLayoutParams(rowparams);
TableRow docrow = new TableRow(SimpleListViewActivity.this);
docrow.setLayoutParams(rowparams);
TableRow namerow = new TableRow(SimpleListViewActivity.this);
namerow.setLayoutParams(rowparams); // Fixed By Praveen

grouprow.addView(groupTxt);
grouprow.addView(nameEdt3);
clientrow.addView(clientTxt);
clientrow.addView(nameEdt2);
docrow.addView(docTxt);
docrow.addView(nameEdt1);
namerow.addView(nameTxt);
namerow.addView(nameEdt);

layout1.addView(grouprow);
layout1.addView(clientrow);
layout1.addView(docrow);
layout1.addView(namerow);



myDialog.setPositiveButton("OK", new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int whichButton) {
        // do nothing 
            System.out.println("Inside Ok");
        }
    });

myDialog.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int whichButton) {
    // do nothing
    }
    });
myDialog.setView(layout1);
AlertDialog alertDialog = myDialog.create();
alertDialog.show();
//alertDialog.getWindow().setLayout(200, 800);
    }

出力 UI は次のとおりです。

ビューの設定方法を教えてください。
