Inspector is a simple and powerful rule-based UI form validation library for Android.
- Works with any view.
- Isolates validation logic using rules.
- Extensible. You can create your own rules.
- Checking dependent fields
Step 1 - init Inspector.
public class MainActivity extends Activity {
private Inspector inspector;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
inspector = new Inspector();
}
@Override
protected void onDestroy() {
inspector.clear();
super.onDestroy();
}
}If you use AppCompat library:
public class MainActivity extends AppCompatActivity {
private Inspector inspector;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
inspector = new Inspector(getLifecycle());
}
}Step 2 - Instantiate a new Inspection
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Code…
Inspection<String> inspectionView = new TextInputLayoutInspectViewBuilder(til1)
.addRule(new TextNotEmptyRule("Поле 1 не должно быть пустым"))
.build();
Inspection<String> inspectionVariable = new InspectVariableBuilder<>("ss")
.addRule(new TextNotEmptyRule("ins3"))
.build();
// More code…
}Step 3 - add Inspection in Inspector
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Code…
inspector.addInspection(inspectionView);
inspector.addInspection(inspectionVariable);
//or
inspector.addInspection(KEY_1, inspectionView);
inspector.addInspection(KEY_2, inspectionVariable);
}Step 4 - Validate
button.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
boolean isValid = inspector.inspect();
//more code...
}
});You can use the OnInspectListener to get the result of the check and the variables:
inspector.setInspectListener(new Inspector.OnInspectListener() {
@Override
public void onInspect(boolean isValid, Map<String, Object> values) {
if (isValid){
presenter.setKey1(values.get(KEY_1));
presenter.setKey2(values.get(KEY_2));
}
}
});Please visit the wiki for a complete guide on Inspector.
