我的應用程序中的一個活動(我的第一次嘗試)生成多個錶行,每行表中包含一對EditText和一個Button。但是,該按鈕始終顯示爲未對齊,導致this problem - 刪除按鈕略微向下移動。Android:在TableRow中排列視圖以編程方式
的XML佈局的相關部分如下:
<ScrollView
android:id="@+id/countEditList"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<TableLayout
android:id="@+id/countEditLayout"
android:stretchColumns="*"
android:gravity="center"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<!-- insert the new rows here as they are created -->
</TableLayout>
</ScrollView>
從一個數據庫遊標創建每一行代碼執行以下操作:
TableRow row = new TableRow(this);
EditText title = new EditText(this);
title.setHorizontallyScrolling(true);
title.setGravity(Gravity.CENTER);
title.setLayoutParams(new TableRow.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
EditText counting = new EditText(this);
counting.setLayoutParams(new TableRow.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
counting.setGravity(Gravity.CENTER);
Button deleteCount = new Button(this);
deleteCount.setLayoutParams(new TableRow.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
deleteCount.setText(R.string.deleteCount);
deleteCount.setOnClickListener(this);
deleteCount.setGravity(Gravity.CENTER);
row.addView(title);
row.addView(counting);
row.addView(deleteCount);
layout.addView(row,new TableLayout.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT)); // Earlier: layout = (ViewGroup) findViewById(R.id.countEditLayout);
我懷疑,我應該以某種方式是設置EditTexts和Button的layout_gravity,但我無法解決如何做到這一點 - 任何人都可以提供任何建議嗎?
感謝您的答覆。不幸的是,這似乎並沒有改變行內deleteCount按鈕的相對對齊。我是否應該爲此使用其他某種佈局,而不是表格? – knirirr 2012-02-17 14:17:44
終於明白了! row.setGravity(Gravity.CENTER);看起來像它的伎倆。 – knirirr 2012-02-17 14:26:12
