कैसे एंड्रॉयड

Question

में कैमरा कैप्चरिंग छवि पर लाइव फ़्रेम स्थापित करने के लिए मैं पिक ऊपर की तरह कैमरे पर लाइव फ्रेम सेट करना होगा। लेकिन मेरा setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);getWidth();getHeight();Camera.PictureCallback आदि बहिष्कृत हैं। उपर्युक्त प्राप्त करने के लिए कोई भी कोड जानता है?

मैं

वास्तव में इस्तेमाल किया, काफी सब कुछ मान्य नहीं है। कोई विचार?

इस नमूने के आधार पर android-Camera2Basic

मैं कुछ परिवर्तन लागू कर दिया गया है और इस परिणाम है:

Camera2BasicFragmentFront.java

Camera2BasicFragment.java

Source

AutoFitTextureView.java

Source

fragment_camera2_basic.xml (com.YourPackage.AutoFitTextureView को बदलने के लिए सुनिश्चित करें)

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent"

    <com.YourPackage.AutoFitTextureView

     android:layout_height="wrap_content" 
     android:layout_alignParentStart="true" 
     android:layout_alignParentTop="true" /> 

</RelativeLayout> 

activity_main.xml

<RelativeLayout android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    xmlns:android="http://schemas.android.com/apk/res/android"> 
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:id="@+id/container" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" > 
</FrameLayout> 
<FrameLayout 
android:id="@+id/containerFront" 
android:layout_width="200dp" 
android:layout_height="200dp" /> 
</RelativeLayout> 

MainActivity.java में से:

public class MainActivity extends AppCompatActivity{ 
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 
     if (null == savedInstanceState) { 
      getFragmentManager().beginTransaction() 
        .replace(R.id.container, Camera2BasicFragment.newInstance()) 
        .commit(); 
      getFragmentManager().beginTransaction() 
        .replace(R.id.containerFront, Camera2BasicFragmentFront.newInstance()) 
        .commit(); 
     } 
    } 
} 

और इस अनुमति का उपयोग Manifest.xml

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

करने के लिए सभी का आनंद है कि!
