我正在尝试制作网格视图,因为这对更多设备更好。我已经尝试在界面构建器中添加我的按钮(因为我将它们添加为ImageButtons,因为它的大小并不好),结果就是在这个屏幕中:http://i.imgur.com/pTJnKOv.png
任何人都可以通过在GridView中制作它来帮助我,完全相同但在所有设备上兼容。
提前致谢;)!
这是ImageAdapter:
public class ImageAdapter extends BaseAdapter {
private Context context;
private final String[] buttonValues;
public ImageAdapter(Context context, String[] buttonValues) {
this.context = context;
this.buttonValues = buttonValues;
}
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View gridView;
if (convertView == null) {
gridView = new View(context);
// get layout from mobile.xml
gridView = inflater.inflate(R.layout.mobile, null);
// set image based on selected text
ImageView imageView = (ImageView) gridView
.findViewById(R.id.grid_item_image);
String button = buttonValues[position];
if (button.equals("homework")) {
imageView.setImageResource(R.drawable.homework);
} else if (button.equals("schedule")) {
imageView.setImageResource(R.drawable.schedulebut);
} else if (button.equals("planner")) {
imageView.setImageResource(R.drawable.plannerbut);
} else {
imageView.setImageResource(R.drawable.settingsbut);
}
} else {
gridView = (View) convertView;
}
return gridView;
}
@Override
public int getCount() {
return buttonValues.length;
}
@Override
public Object getItem(int position) {
return null;
}
@Override
public long getItemId(int position) {
return 0;
}
}
这是我在onCreate中的方法:
static final String[] MOBILE_OS = new String[] { "Homework", "Schedule",
"Planner", "Settings" };
private void setGridView() {
gridView = (GridView) findViewById(R.id.gridView1);
gridView.setAdapter(new ImageAdapter(this, MOBILE_OS));
gridView.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View v,
int position, long id) {
Toast.makeText(getApplicationContext(), "LOL!", Toast.LENGTH_SHORT).show();
}
});
}

由于您尝试使用 2X2网格并且只有4个元素,因此请使用 android:numColumns="2"
作为GridView的属性。
此外,还有这个优秀的tutorial on GridViews!
仅在网格中实现图片的代码段:
public class ImageAdapter extends BaseAdapter {
private Context context;
public ImageAdapter(Context context) {
this.context = context;
}
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View gridView;
if (convertView == null) {
gridView = new View(context);
// get layout from mobile.xml
gridView = inflater.inflate(R.layout.mobile, null);
// set image based on selected text
ImageView imageView = (ImageView) gridView
.findViewById(R.id.grid_item_image);
if (mobile.equals("Windows")) {
imageView.setImageResource(R.drawable.windows_logo);
} else if (mobile.equals("iOS")) {
imageView.setImageResource(R.drawable.ios_logo);
} else if (mobile.equals("Blackberry")) {
imageView.setImageResource(R.drawable.blackberry_logo);
} else {
imageView.setImageResource(R.drawable.android_logo);
}
} else {
gridView = (View) convertView;
}
return gridView;
}
@Override
public int getCount() {
return mobiles.length;
}
@Override
public Object getItem(int position) {
return null;
}
@Override
public long getItemId(int position) {
return 0;
}
}
编辑:您在所有按钮中获得相同的图像,因为您匹配在不同情况下编写的字符串。 (你在一个地方使用&#34;家庭作业&#34; ,在另一个地方使用&#34;家庭作业&#34; )
所以,使用static final String[] MOBILE_OS = new String[] { "homework", "schedule", "planner", "settings" };
,它会正常工作。

要获得固定尺寸,您可以添加
机器人:layout_height = “” 机器人:layout_width = “”
示例:
机器人:layout_height = “100dp” 机器人:layout_width = “200dp”
按钮标签中的
