可以看到VideoView的寬和高屬性都已經設為"fill_parent"了 , 但事實上執行的結果並不會填滿整個parent layout , 如果想更改大小的話目前比較簡單的方法是寬設為"xxdip"來解決 , 不過只有更改寬的dip才會起作用 , 高的部分怎麼改都一樣 , 應該是有更好的方法來修改VideoView的寬和高。在網路上看到一篇文章有解決這個問題 , 照他的方法做程式碼如下
import android.content.Context;
import android.util.AttributeSet;
import android.util.Log;
import android.widget.VideoView;
public class CustomVideoView extends VideoView
{
public CustomVideoView(Context context)
{
super(context);
// TODO Auto-generated constructor stub
Log.d("Go to", "Context context");
}
public CustomVideoView(Context context, AttributeSet attrs)
{
super(context, attrs);
// TODO Auto-generated constructor stub
mVideoWidth = 0;
mVideoHeight = 0;
Log.d("Go to", "Context context, AttributeSet attrs");
}
//可以發現進入的是CustomVideoView(Context context, AttributeSet attrs)這個建構子
//所以留著覆寫他 , 否則程式會強制關閉
public void onMeasure (int widthMeasureSpec, int heightMeasureSpec)
{
int width = getDefaultSize(mVideoWidth, widthMeasureSpec);
int height = getDefaultSize(mVideoHeight, heightMeasureSpec);
setMeasuredDimension(width,height);
}
private int mVideoWidth;
private int mVideoHeight;
}
