我正在尝试在图像上应用图像效果。
这是我正在尝试的代码。
select CAST( 1234567890 AS DECIMAL(10,2)) from SYSIBM.SYSDUMMY1;
当我运行此代码时，应用程序不会崩溃，但始终会显示public class MainActivity extends AppCompatActivity {
public ImageView imageView;
public ImageButton btn1, btn2, btn3, btn4, btn5, btn6;
private Bitmap operation;
public Bitmap bmp;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
imageView = (ImageView) findViewById(R.id.imageView);
btn1 = (ImageButton) findViewById(R.id.imageButton);
btn1.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
ImageFilter imageFilter = new ImageFilter(MainActivity.this);
imageFilter.execute();
}
});
BitmapDrawable abmp = (BitmapDrawable) imageView.getDrawable();
bmp = abmp.getBitmap();
}
public class ImageFilter extends AsyncTask<Void, Void, Bitmap> {
Context context;
public ProgressDialog progressDialog;
public ImageFilter(Context ctx){
context = ctx;
}
@Override
protected Bitmap doInBackground(Void... params) {
operation = Bitmap.createBitmap(bmp.getWidth(),bmp.getHeight(), bmp.getConfig());
double red = 0.33;
double green = 0.59;
double blue = 0.11;
for (int i = 0; i < bmp.getWidth(); i++) {
for (int j = 0; j < bmp.getHeight(); j++) {
int p = bmp.getPixel(i, j);
int r = Color.red(p);
int g = Color.green(p);
int b = Color.blue(p);
r = (int) red * r;
g = (int) green * g;
b = (int) blue * b;
operation.setPixel(i, j, Color.argb(Color.alpha(p), r, g, b));
}
}
return operation;
}
@Override
protected void onPreExecute() {
progressDialog = new ProgressDialog(context);
progressDialog.setMessage("Processing...");
progressDialog.show();
}
@Override
protected void onPostExecute(Bitmap bitmap) {
imageView.setImageBitmap(bitmap);
progressDialog.dismiss();
}
}
}
根本没有影响图像。我检查了日志，发现了两个警告。
警告＃1
processDialog警告＃2
W/art: Before Android 4.1, method android.graphics.PorterDuffColorFilter
我的代码有什么问题？
