xml：
activity：
package com.wj.cameratest;
import java.io.File;
import android.app.Activity;
import android.content.Intent;
import android.graphics.drawable.Drawable;
import android.net.Uri;
import android.os.Bundle;
import android.os.Environment;
import android.provider.MediaStore;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.ImageView;
public class CameraShowActivity extends Activity {
private ImageView mImageView;
private Button mButtonCamera;
private Button mButtonPhoto;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_camera_show);
mImageView = (ImageView) this.findViewById(R.id.imageview_preview);
mButtonCamera = (Button) this.findViewById(R.id.button_cameraButton);
mButtonPhoto = (Button) this.findViewById(R.id.button_photoButton);
mButtonCamera.setOnClickListener(new OnClickListener() { //打开Camera
@Override
public void onClick(View v) {
Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
intent.putExtra(MediaStore.EXTRA_OUTPUT,
Uri.fromFile(new File(Environment
.getExternalStorageDirectory(), "camera.jpg")));
intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 0);
startActivityForResult(intent, 10);
}
});
mButtonPhoto.setOnClickListener(new OnClickListener() { //获取相册
@Override
public void onClick(View v) {
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.addCategory(Intent.CATEGORY_OPENABLE);
intent.setType("image/*");
intent.putExtra("crop", "true");
intent.putExtra("aspectX",1);
intent.putExtra("aspectY",1);
intent.putExtra("outputX", 80);
intent.putExtra("outputY", 80);
intent.putExtra("return-data",true);
startActivityForResult(intent, 11);
}
});
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == 10 && resultCode == Activity.RESULT_OK) {
this.mImageView.setImageDrawable(Drawable.createFromPath(new File(
Environment.getExternalStorageDirectory(), "camera.jpg")
.getAbsolutePath()));
System.out.println("data-->"+data);
}else if (requestCode == 11 && resultCode ==Activity.RESULT_OK) {
System.out.println("data2-->"+data);
}
}
}Manifest.xml
android 调用相册里的图片并返回
Intent intent=new Intent(Intent.ACTION_GET_CONTENT);
intent.addCategory(Intent.CATEGORY_OPENABLE);
intent.setType("image/*");
intent.putExtra("crop", "true");
intent.putExtra("aspectX", 1);
intent.putExtra("aspectY", 1);
intent.putExtra("outputX", 80);
intent.putExtra("outputY", 80);
intent.putExtra("return-data", true);
startActivityForResult(intent, 0);在原来的Activity中如下获取选到的图片：
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
System.out.println(resultCode);
Bitmap cameraBitmap = (Bitmap) data.getExtras().get("data");
super.onActivityResult(requestCode, resultCode, data);
