超级高仿 ios 相册编辑功能的旋转操作
Step 1. Add the JitPack repository to your build file
allprojects {
repositories {
...
maven { url 'https://jitpack.io' }
}
}
Step 2. Add the dependency
dependencies {
compile 'com.github.tanzby:RotateControlView:v0.99'
}
Step 3. In your style xml file
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="pub.tanzby.rotatableview.MainActivity">
<android.support.constraint.ConstraintLayout
android:id="@+id/constraintLayout2"
android:layout_width="match_parent"
android:layout_height="320dp"
android:background="#0ff">
<ImageView
android:id="@+id/imageView"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginBottom="8dp"
android:layout_marginEnd="8dp"
android:layout_marginStart="8dp"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"

app:layout_constraintTop_toTopOf="parent"
app:srcCompat="@drawable/ic_launcher_background" />
<TextView

android:layout_marginTop="44dp"
android:text="TextView"

app:layout_constraintTop_toTopOf="parent" />
</android.support.constraint.ConstraintLayout>
<pub.tanzby.rotatecontrolview.RotateControlView
android:id="@+id/rv"
android:layout_width="0dp"

app:layout_constraintRight_toRightOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="@+id/constraintLayout2" />
</android.support.constraint.ConstraintLayout>Step 3. In your Java class
public class MainActivity extends AppCompatActivity {
RotateControlView rv;
ImageView img;
TextView tv;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
img = findViewById(R.id.imageView);
tv = findViewById(R.id.textView);
rv = findViewById(R.id.rv);
rv.addTargetView(img); // bind with your view wanted to control
rv.setOnRotateOperatorListener(new RotateControlView.OnRotateOperatorListener() {
@Override
public void OnRotate(float angle) {
tv.setText("angle: " + angle);
}
@Override
public void OnClickRotate(float angle) {
tv.setText("angle: " + angle);
}
});
}
}
