Android studio Textecture_view code Example

                Android Textecture_view Example

Let us start actual programming with Android Studio
Before you start writing your Android Texture Example example using Android SDK,
you have to make sure that you have set-up your Android development
environment properly as explained in Android

Create Android Application

1. The Application First Step Create a New Project Start project

2. Rename Application Name Below Screen Ex: Android Texture
Click Next

3. After Spacific Minium sdk API 23 Select Lolipop 5.0
Click Next

4. Final Select Blank Activity Click Next

5. Then Select MainActivity Click Finish

6. Then Open a Android Studio

1.MainActivity.java

import android.view.TextureView.SurfaceTextureListener;
import android.view.View;
import android.widget.FrameLayout;

public class MainActivity extends Activity implements SurfaceTextureListener {
    private TextureView myTexture;
    private Camera mCamera;

    @SuppressLint("NewApi")

        myTexture.setSurfaceTextureListener(this);
        setContentView(myTexture);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.menu_main, menu);
        return true;

        mCamera = Camera.open();
        Camera.Size previewSize = mCamera.getParameters().getPreviewSize();

        myTexture.setLayoutParams(new FrameLayout.LayoutParams(
                previewSize.width, previewSize.height, Gravity.CENTER));

        try {
            mCamera.setPreviewTexture(arg0);
        }

        catch (IOException t) {
        }
        mCamera.startPreview();
        myTexture.setAlpha(1.0f);
        myTexture.setRotation(90.0f);
    }

    @Override

        mCamera.stopPreview();
        mCamera.release();
        return true;
    }

    @Override

                                            int arg2) {
        // TODO Auto-generated method stub
    }
    @Override

        // TODO Auto-generated method stub
    }
}
