我是Android新手,我嘗試製作帶有可滾動文本的頁面。我正在使用相對佈局線性佈局和滾動。但不知怎的,文本從開始就不畫。Android佈局查看與其他按鈕的頁面中的可縮小文本
前3行沒有繪製(Title1,Title2,Title3),因爲它們在滾動區域之外。但爲什麼?滾動工作/顯示罰款在指定區域從2個按鈕,如下所示: 我在這裏設置android:layout_below =「@ id/button_s」 android:layout_above =「@ id/button_c」滾動的邊距,但仍然是文本顯示在邊距之外。我做錯了什麼?爲什麼我在其中繪製文本的線性佈局lin2從屏幕頂部開始?我爲它設置了android:layout_below。
這裏是我的代碼:
的main.xml:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/relative_layout"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TextView
android:id="@+id/tv"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:text="@string/my_app" />
<Button
android:id="@+id/button_s"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_below="@id/tv"
android:text="@string/search" />
<Button
android:id="@+id/button_c"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_alignParentBottom="true"
android:text="@string/config" />
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:scrollbars="vertical"
android:layout_below="@id/button_s"
android:layout_above="@id/button_c" android:id="@+id/ScrollView">
<LinearLayout
android:layout_width="fill_parent"
android:orientation="vertical"
android:id="@+id/lin2"
android:layout_height="wrap_content"
android:layout_below="@id/button_s"
android:layout_above="@id/button_c"
android:layout_gravity="center_vertical|center_horizontal">
</LinearLayout>
</ScrollView>
</RelativeLayout>
我的Java文件:
String[] strTitles ={"Title 1: test test test test test test test test",
"Title 2: test test test test test",
"Title 3: test test test test test",
"Title 4: test test test test",
"Title 5: test test test",
"Title 6: test test test test",
"Title 7: test test test test",
"Title 8: test test test test test",
"Title 9: test test test test test",
"Title 9: test test test test test",
"Title 10: test test test test",
"Title 11: test test test test test",
"Title 12: test test test test test",
"Title 13: test test test test test",
"Title 14: test test "};
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
LinearLayout ll = (LinearLayout)findViewById(R.id.lin2);
for (int i = 0 ; i < strTitles.length * 2 ; i++)
{
String strToDisplay = " ";
if(i%2 == 1)
strToDisplay = " ";
else
{
strToDisplay = strTitles[i/2];
}
TextView tv = new TextView(this);
tv.setText(strToDisplay);
ll.addView(tv);
tv.setGravity(Gravity.CENTER_VERTICAL | Gravity.CENTER_HORIZONTAL);
}
}
感謝
@Dorian你也可以在循環中使用「\ n」。 for(int i = 0; i
