xml：
<linearlayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<button

android:text="拍照" />
<button

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
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.wj.cameratest"
android:versioncode="1"
android:versionname="1.0" >
<uses-sdk
android:minsdkversion="8"
android:targetsdkversion="15" />
<uses-permission android:name="android.permission.camera" />
<uses-permission android:name="android.permission.mount_unmount_filesystems" />
<uses-permission android:name="android.permission.write_external_storage" />
<uses-feature android:name="android.hardware.camera" />
<uses-feature android:name="android.hardware.camera.autofocus" />
<application
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/apptheme" >
<activity
android:name=".camerashowactivity"
android:label="@string/title_activity_camera_show" >
<intent-filter>
<action android:name="android.intent.action.main" />
<category android:name="android.intent.category.launcher" />
</intent-filter>
</activity>
</application>
</manifest>
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);
}
