我想要一个 2 列ScrollView
.在每一列中,应该有一个ImageButton
:
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/scrollView1"
android:layout_height="800dp"
android:background="#FFF"
android:layout_width="600dp" >
<LinearLayout
android:id="@+id/categoryLinearLayout1"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
</LinearLayout>
</ScrollView>
和代码:
LinearLayout sv = (LinearLayout) findViewById(R.id.categoryLinearLayout1);
for (int i = 0; i < 10; i++) {
ImageButton ib = new ImageButton(this);
// ib.setImageDrawable(getResources().getDrawable(R.drawable.cat1));
Bitmap bmp = BitmapFactory.decodeResource(getResources(),
R.drawable.cat1);
int width = 300;
int height = 300;
Bitmap resizedbitmap = Bitmap.createScaledBitmap(bmp, width,
height, true);
ib.setImageBitmap(resizedbitmap);
sv.addView(ib);
}
但这样,所有 10 个都是水平ImageButtons
的。我需要的是,连续放 2 个ImageButton
(它使 600px)然后向下,放置更多 2 个ImageButtons
等。所以 5 行 10 ImageButtons
.
我该怎么做?
使用TableLayout
:
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/scrollView1"
android:layout_height="800dp"
android:background="#FFF"
android:layout_width="600dp" >
<TableLayout
android:id="@+id/categoryLinearLayout1"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
</TableLayout>
</ScrollView>
然后在代码中:
TableLayout sv = (TableLayout) findViewById(R.id.categoryLinearLayout1);
for (int i = 0; i < 5; i++) {
TableRow tr = new TableRow(this);
tr.setLayoutParams(new TableLayout.LayoutParams(TableLayout.LayoutParams.FILL_PARENT, TableLayout.LayoutParams.WRAP_CONTENT));
for (int j = 0; j < 2; j++) {
ImageButton ib = new ImageButton(this);
// ib.setImageDrawable(getResources().getDrawable(R.drawable.cat1));
Bitmap bmp = BitmapFactory.decodeResource(getResources(),
R.drawable.cat1);
int width = 300;
int height = 300;
Bitmap resizedbitmap = Bitmap.createScaledBitmap(bmp, width,
height, true);
ib.setImageBitmap(resizedbitmap);
ib.setLayoutParams(new TableRow.LayoutParams(TableRow.LayoutParams.WRAP_CONTENT, TableRow.LayoutParams.WRAP_CONTENT));
tr.addView(ib);
}
sv.add(tr);
}
