- Step 1：Add the JitPack repository to your build file
Add it in your root build.gradle at the end of repositories:
allprojects {
repositories {
...
maven { url 'https://jitpack.io' }
}
}
- Step 2：Add the dependency
The latest version shall prevail.
dependencies {
implementation 'com.github.huangziye:scanner:${latest_version}'
}
private final String[] perms = {Manifest.permission.CAMERA};
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
findViewById(R.id.btn_open_camera).setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if (ContextCompat.checkSelfPermission(MainActivity.this, Manifest.permission.CAMERA) == PackageManager.PERMISSION_GRANTED) {
startActivityForResult(new Intent(MainActivity.this, CaptureActivity.class), 100);
} else {
ActivityCompat.requestPermissions(MainActivity.this, perms, 100);
}
}
});
}
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
if (requestCode == 100 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
startActivityForResult(new Intent(MainActivity.this, CaptureActivity.class), 100);
}
}
@Override
protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (100 == requestCode && resultCode == Activity.RESULT_OK) {
Toast.makeText(MainActivity.this, data.getStringExtra(CaptureActivity.RESULT_DATA_KEY), Toast.LENGTH_SHORT).show();
}
