Android-GridView填充问题
|
我正在将图像加载到
GridView
package com.android.sampleDesign1;
import android.content.Context;
import android.text.Layout;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.view.ViewGroup.LayoutParams;
import android.widget.BaseAdapter;
import android.widget.GridView;
import android.widget.ImageView;
import android.widget.Toast;
public class TicTacToeAdapter extends BaseAdapter {
public ImageView imageView;
private Context mContext;
private Integer mThumbIds = R.drawable.images;
private Integer image;
public TicTacToeAdapter(Context c) {
mContext = c;
}
public int getCount() {
return 9;
}
public Object getItem(int position) {
return position;
}
public long getItemId(int position) {
return position;
}
public View getView(int position, View convertView, ViewGroup parent) {
image = mThumbIds;
if (convertView == null) {
imageView = new ImageView(mContext);
imageView.setLayoutParams(new GridView.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));
imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
imageView.setImageResource(image);
imageView.setPadding(10,10,10,10);
} else {
imageView = (ImageView) convertView;
imageView.setImageResource(image);
}
return imageView;
}
}
int w = gridView.getWidth();
int myViewWidth = Math.round(W * .12f);
LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.FILL_PARENT, LinearLayout.LayoutParams.FILL_PARENT);
lp.setMargins(left, top, right, bottom);
imageView.setLayoutParams(lp);

中定义填充，您需要在（与密度无关的像素）中定义填充，然后在运行时将转换为。 所以你需要做类似的事情private static final float PADDING_IN_DP = 10.0f; // 1 dip = 1 pixel on an MDPI device private final int mPaddingInPixels; public TicTacToeAdapter(Context context) { .... // Convert the dps to pixels final float scale = context.getResources().getDisplayMetrics().density; mPaddingInPixels = (int) (PADDING_IN_DP * scale + 0.5f); } ... public View getView(int position, View convertView, ViewGroup parent) { ... if (convertView == null) { ... imageView.setPadding(mPaddingInPixels, mPaddingInPixels, mPaddingInPixels, mPaddingInPixels); } ... } ...会根据运行应用程序的设备的屏幕密度而有所不同。 （注意：和是同一件事）
