Android 应用程序->；摄像头->；照片->；低分辨率

问题:

    </application>
    <uses-sdk android:minSdkVersion="8" />
<uses-permission android:name="android.permission.CAMERA" />
   <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-feature android:name="android.hardware.camera"/>
<uses-feature android:name="android.hardware.camera.autofocus"/></manifest>

当我使用我的应用程序拍摄照片并将其存储在SD上时，分辨率为160x120。 如果使用普通照相机，照片的分辨率为1920x2560

    </application>
    <uses-sdk android:minSdkVersion="8" />
<uses-permission android:name="android.permission.CAMERA" />
   <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-feature android:name="android.hardware.camera"/>
<uses-feature android:name="android.hardware.camera.autofocus"/></manifest>

所以，请帮我说说我必须做些什么来强制相机，从应用程序开始，以标准的高分辨率拍照

    </application>
    <uses-sdk android:minSdkVersion="8" />
<uses-permission android:name="android.permission.CAMERA" />
   <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-feature android:name="android.hardware.camera"/>
<uses-feature android:name="android.hardware.camera.autofocus"/></manifest>

这是我用于启动照相机意图和保存照片的代码：

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE); 
    startActivityForResult(cameraIntent, CAMERA_REQUEST); 
}
public void onActivityResult(int requestCode, int resultCode, Intent data) {  
    if (requestCode == CAMERA_REQUEST) { 

    Bundle xz = data.getExtras();
    if (xz!=null) {

    Bitmap image = (Bitmap) data.getExtras().get("data");

    String filePath = "/mnt/sdcard/DCIM/"; 
    filePath += "hml.png";
 try {
  image.compress(Bitmap.CompressFormat.PNG, 100, new FileOutputStream(new File(filePath)));
 } 
    catch (FileNotFoundException e) {
                 // TODO Auto-generated catch block
                e.printStackTrace();}  
    catch (NullPointerException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();       } 
    }}

    </application>
    <uses-sdk android:minSdkVersion="8" />
<uses-permission android:name="android.permission.CAMERA" />
   <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-feature android:name="android.hardware.camera"/>
<uses-feature android:name="android.hardware.camera.autofocus"/></manifest>

谢谢你

我发现了同样的问题。也许我们用前面的摄像头。我发现还有另外一种方法可以使用相机，并发现代码被吹走了

    </application>
    <uses-sdk android:minSdkVersion="8" />
<uses-permission android:name="android.permission.CAMERA" />
   <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-feature android:name="android.hardware.camera"/>
<uses-feature android:name="android.hardware.camera.autofocus"/></manifest>

AndroidManifest.xml：

    </application>
    <uses-sdk android:minSdkVersion="8" />
<uses-permission android:name="android.permission.CAMERA" />
   <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-feature android:name="android.hardware.camera"/>
<uses-feature android:name="android.hardware.camera.autofocus"/></manifest>

如果您没有为输出图像提供uri，相机意图将只返回图片的缩略图。请按照以下说明正确执行此操作：

在模拟器中也应该这样吗？我仍然得到带有额外输出的缩略图。

    <uses-sdk android:minSdkVersion="8" />
<uses-permission android:name="android.permission.CAMERA" />
   <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

<uses-feature android:name="android.hardware.camera.autofocus"/></manifest>
