Android imageview 未在 TableRow 中顯示 (Android imageview not displaying in TableRow)
I am trying to display a simple ImageView in a TableRow but for some reason it won't display. If I add another control to another row the imageView does display, so it seems like it is just not forcing the size correctly. My xml is as follows:
<TableLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="fill_parent"
android:layout_width="fill_parent"
android:background="#4B088A"
android:id="@+id/ImageTable">
<TableRow android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:padding="5dp"
android:id="@+id/ImageTableRow"/>
</TableLayout>
The code that I am using to add the ImageView is:
TableLayout tableLayout = (TableLayout) findViewById(R.id.ImageTable);
TableRow tr = new TableRow(this);
TableRow.LayoutParams lp = new
TableRow.LayoutParams(TableRow.LayoutParams.MATCH_PARENT ,TableRow.LayoutParams.WRAP_CONTENT);
tr.setLayoutParams(lp);
m_imageView = new MyImageView(getApplicationContext());
m_imageView.setBackgroundColor(Color.GRAY);
m_imageView.setImageBitmap(charty);
tr.addView(m_imageView);
tableLayout.addView(tr);

方法 1:
try this code
write your xml "activity_main" as
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<TableLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
>
<TableRow
android:id="@+id/tableRow1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
>
<ImageView
android:id="@+id/image"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/ic_action_search" />
</TableRow>
</TableLayout>
</LinearLayout>
ic_action_search is your image in drawable folder and write main activity as
public class MainActivity extends Activity
{
ImageView image;
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
}
