我的主要活动中有一个按钮，当它被点击时，它会导致我的GridView活动，但应用程序强制关闭。
这是我的activity_gridview.xml文件：
<?xml version="1.0" encoding="utf-8"?>
<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"
tools:context="com.myapps.gridviewexample.GridViewActivity"
android:padding="4dp">
<GridView
android:id="@+id/gridview"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:numColumns="3"
android:columnWidth="150dp"
android:horizontalSpacing="10dp"
android:verticalSpacing="10dp"
android:gravity="center"
>
</GridView>
</LinearLayout>
GridViewActivity.java：
package com.myapps.gridviewexample;
import android.content.Context;
import android.content.Intent;
import android.content.res.Resources;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;

import android.widget.ImageView;
public class GridViewActivity extends AppCompatActivity {
public Integer[] images = {
R.drawable.pic1,
R.drawable.pic2,
};
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_gridview);
GridView gridview = (GridView) findViewById(R.id.gridview);
if (gridview != null) {
gridview.setAdapter(new ImageAdapter(GridViewActivity.this));
gridview.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View v,
int position, long id) {
Intent intent = new Intent(GridViewActivity.this, TestActivity.class);
GridViewActivity.this.startActivity(intent);
intent.putExtra("POSITION", position + 1);
}
});
}
}
public static int convertDpToPixels(float dp, Context context){
Resources resources = context.getResources();
return (int) TypedValue.applyDimension(
TypedValue.COMPLEX_UNIT_DIP,
dp,
resources.getDisplayMetrics()
);
}
public class ImageAdapter extends BaseAdapter {
private Context mContext;
public int getCount() {
return images.length;
}
public Object getItem(int position) {
return images[position];
}
public long getItemId(int position) {
return 0;
}
public ImageAdapter(Context c) {
mContext = c;
}
public View getView(int position, View convertView, ViewGroup parent) {
ImageView imageView;
if (convertView == null) {
imageView = new ImageView(mContext);
float w = 100;
float h = 100;
int width_pixel = convertDpToPixels(w, GridViewActivity.this);
int height_pixel = convertDpToPixels(h, GridViewActivity.this);
imageView.setLayoutParams(new GridView.LayoutParams(width_pixel, height_pixel));
imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
imageView.setPadding(8, 8, 8, 8);
imageView.setMaxHeight(60);
} else {
imageView = (ImageView) convertView;
}
imageView.setBackgroundResource(images[position]);
return imageView;
}
}
}
logcat输出：

对于遇到大图片问题的人，请查看Loading Large Bitmaps Efficiently上的google文档，了解如何在没有 OutOfMemoryError 的情况下加载大图片。另请查看修复相同问题的Adam Stelmaszczyk's code。
