如何捕捉圖片並在android中預覽相同？

Question

public class CameraActivity extends Activity { 

Button camera; 
ImageView imv; 
final static int CAMERA_RESULT = 0; 
Intent i; 

/** Called when the activity is first created. */ 
@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.main); 

    camera = (Button) findViewById(R.id.button1); 
    imv = (ImageView) findViewById(R.id.imageView1); 
    camera.setOnClickListener(new View.OnClickListener() { 

     @Override 
     public void onClick(View arg0) { 
      // TODO Auto-generated method stub 
      i = new Intent(
      "android.provider.MediaStore.ACTION_IMAGE_CAPTURE"); 
    startActivityForResult(i, CAMERA_RESULT); 
     } 
    }); 
    } 
    protected void onActivityResult(int requestCode, int resultCode, 
     Intent intent) { 
    super.onActivityResult(requestCode, resultCode, intent); 
    if (resultCode == RESULT_OK) { 
     Bundle extras = intent.getExtras(); 
     Bitmap bmp = (Bitmap) extras.get("data"); 
     imv = (ImageView) findViewById(R.id.imageView1); 
     imv.setImageBitmap(bmp); 
    } 
    } 
    } 

main.xml中

<?xml version="1.0" encoding="utf-8"?> 
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="fill_parent" 
android:layout_height="fill_parent" 
android:orientation="vertical" > 

<ImageView 
    android:id="@+id/imageView1" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    /> 

<Button 
    android:id="@+id/button1" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:text="Button" /> 
</LinearLayout> 

的manifest.xml

<?xml version="1.0" encoding="utf-8"?> 
<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
package="camera.mohit" 
android:versionCode="1" 
android:versionName="1.0" > 
<uses-sdk android:minSdkVersion="8" /> 
<uses-feature android:name="android.hardware.camera"></uses-feature> 
<uses-permission android:name="android.permission.CAMERA"/> 
<application 
    android:icon="@drawable/ic_launcher" 
    android:label="@string/app_name" > 
    <activity 
     android:name=".CameraActivity" 
     android:label="@string/app_name" > 
     <intent-filter> 
      <action android:name="android.intent.action.MAIN" /> 

      <category android:name="android.intent.category.LAUNCHER" /> 
     </intent-filter> 
    </activity> 
</application>

以上是我的3個文件，我使用從獲得PIC預覽相機。我已經通過這個線程：Capture Image from Camera and Display in Activity。不知道爲什麼，但事情變得越來越糟糕。

Answer 1

你可以試試嗎？

Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); 

這條線正在我的手機和仿真器和ACTION_IMAGE_CAPTURE值：

public static final java.lang.String ACTION_IMAGE_CAPTURE = "android.media.action.IMAGE_CAPTURE";
