Android 調用系統照相機拍照和錄影_Android

本文實現android系統照相機的調用來拍照

項目的布局相當簡單，只有一個Button：

<RelativeLayout 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=".MainActivity" >  <Button    android:onClick="click"    android:layout_width="wrap_content"    android:layout_height="wrap_content"    android:layout_centerHorizontal="true"    android:layout_centerVertical="true"    android:text="調用系統相機拍照" /></RelativeLayout>

首先開啟packages\apps\Camera檔案夾下面的資訊清單檔，找到下面的代碼：

<activity android:name="com.android.camera.Camera"        android:configChanges="orientation|keyboardHidden"        android:theme="@android:style/Theme.Black.NoTitleBar.Fullscreen"        android:screenOrientation="landscape"        android:clearTaskOnLaunch="true"        android:taskAffinity="android.task.camera">      <intent-filter>        <action android:name="android.intent.action.MAIN" />        <category android:name="android.intent.category.DEFAULT" />        <category android:name="android.intent.category.LAUNCHER" />      </intent-filter>      <intent-filter>        <action android:name="android.media.action.IMAGE_CAPTURE" />        <category android:name="android.intent.category.DEFAULT" />      </intent-filter>      <intent-filter>        <action android:name="android.media.action.STILL_IMAGE_CAMERA" />        <category android:name="android.intent.category.DEFAULT" />      </intent-filter>    </activity>

相關代碼如下:

public class MainActivity extends Activity {  @Override  protected void onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    setContentView(R.layout.activity_main);  }  public void click(View view) {    /*     * <intent-filter> <action     * android:name="android.media.action.IMAGE_CAPTURE" /> <category     * android:name="android.intent.category.DEFAULT" /> </intent-filter>     */    // 啟用系統的照相機進行拍照    Intent intent = new Intent();    intent.setAction("android.media.action.IMAGE_CAPTURE");    intent.addCategory("android.intent.category.DEFAULT");        //儲存照片到指定的路徑    File file = new File("/sdcard/image.jpg");    Uri uri = Uri.fromFile(file);    intent.putExtra(MediaStore.EXTRA_OUTPUT, uri);        startActivity(intent);  }}

實現啟用錄影功能的相關代碼也很簡單：

public class MainActivity extends Activity {  @Override  protected void onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    setContentView(R.layout.activity_main);  }  public void click(View view) {    /*     * <intent-filter> <action     * android:name="android.media.action.VIDEO_CAPTURE" /> <category     * android:name="android.intent.category.DEFAULT" /> </intent-filter>     */    // 啟用系統的照相機進行錄影    Intent intent = new Intent();    intent.setAction("android.media.action.VIDEO_CAPTURE");    intent.addCategory("android.intent.category.DEFAULT");    // 儲存錄影到指定的路徑    File file = new File("/sdcard/video.3pg");    Uri uri = Uri.fromFile(file);    intent.putExtra(MediaStore.EXTRA_OUTPUT, uri);    startActivityForResult(intent, 0);  }    @Override  protected void onActivityResult(int requestCode, int resultCode, Intent data) {    Toast.makeText(this, "調用照相機完畢", 0).show();    super.onActivityResult(requestCode, resultCode, data);      }}
