对应另外一个Activity中实现读取与组装Bitmap对象显示的代码如下：
package com.example.sharedemo;
import java.io.FileNotFoundException;
import android.app.Activity;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.os.Bundle;
import android.widget.ImageView;
import android.widget.TextView;
public class ImageProcessActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.share_info);
backFillData();
}
private void backFillData() {
Object obj = this.getIntent().getExtras().get("tiger");
ImageView imageView = (ImageView)this.findViewById(R.id.imageView1);
TextView text1 = (TextView)this.findViewById(R.id.textView1);
TextView text2 = (TextView)this.findViewById(R.id.textView2);
try {
if(obj != null && obj instanceof ImageInfoBean)
{
ImageInfoBean dto = (ImageInfoBean)obj;
Bitmap bitmap = BitmapFactory.decodeStream(this.openFileInput(dto.getUri()));
imageView.setImageBitmap(bitmap);
imageView.invalidate(); // refresh
text1.setText("名称: " + dto.getName());
text2.setText("描述: " + dto.getDescription());
return;
}
} catch (FileNotFoundException e) {
e.printStackTrace();
}
Bitmap bitmap = (Bitmap) this.getIntent().getParcelableExtra("selectedImage");
String name = this.getIntent().getExtras().getString("name");
String description = this.getIntent().getExtras().getString("description");
if(bitmap != null)
{
imageView.setImageBitmap(bitmap);
imageView.invalidate(); // refresh
}
if(name != null)
{
text1.setText("名称: " + name);
}
if(description != null)
{
text2.setText("描述: " + description);
}
}
}
对应的Java串行化对象类代码如下：
package com.example.sharedemo;
import java.io.Serializable;
public class ImageInfoBean implements Serializable {
/**
*
*/
private static final long serialVersionUID = 1L;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getDescription() {
return description;
}
public void setDescription(String description) {
this.description = description;
}
public String getUri() {
return uri;
}
public void setUri(String uri) {
this.uri = uri;
}
private String name;
private String description;
private String uri;
}
