您可以使用子佈局的這個六邊形的ImageView和調整頁邊距
import android.content.Context;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Paint;
import android.graphics.Path;
import android.graphics.PorterDuff;
import android.graphics.Region;
import android.util.AttributeSet;
import android.widget.ImageView;
public class HexagonMaskView extends ImageView {
private Path hexagonPath;
private Path hexagonBorderPath;
private Paint mBorderPaint;
public HexagonMaskView(Context context) {
super(context);
init();
}
public HexagonMaskView(Context context, AttributeSet attrs) {
super(context, attrs);
init();
}
public HexagonMaskView(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
init();
}
private void init() {
this.hexagonPath = new Path();
this.hexagonBorderPath = new Path();
this.mBorderPaint = new Paint();
this.mBorderPaint.setColor(Color.WHITE);
this.mBorderPaint.setStrokeCap(Paint.Cap.ROUND);
this.mBorderPaint.setStrokeWidth(50f);
this.mBorderPaint.setStyle(Paint.Style.STROKE);
}
public void setRadius(float radius) {
calculatePath(radius);
}
public void setBorderColor(int color) {
this.mBorderPaint.setColor(color);
invalidate();
}
private void calculatePath(float radius) {
float halfRadius = radius/2f;
float triangleHeight = (float) (Math.sqrt(3.0) * halfRadius);
float centerX = getMeasuredWidth()/2f;
float centerY = getMeasuredHeight()/2f;
this.hexagonPath.reset();
this.hexagonPath.moveTo(centerX, centerY + radius);
this.hexagonPath.lineTo(centerX - triangleHeight, centerY + halfRadius);
this.hexagonPath.lineTo(centerX - triangleHeight, centerY - halfRadius);
this.hexagonPath.lineTo(centerX, centerY - radius);
this.hexagonPath.lineTo(centerX + triangleHeight, centerY - halfRadius);
this.hexagonPath.lineTo(centerX + triangleHeight, centerY + halfRadius);
this.hexagonPath.close();
float radiusBorder = radius - 5f;
float halfRadiusBorder = radiusBorder/2f;
float triangleBorderHeight = (float) (Math.sqrt(3.0) * halfRadiusBorder);
this.hexagonBorderPath.reset();
this.hexagonBorderPath.moveTo(centerX, centerY + radiusBorder);
this.hexagonBorderPath.lineTo(centerX - triangleBorderHeight, centerY + halfRadiusBorder);
this.hexagonBorderPath.lineTo(centerX - triangleBorderHeight, centerY - halfRadiusBorder);
this.hexagonBorderPath.lineTo(centerX, centerY - radiusBorder);
this.hexagonBorderPath.lineTo(centerX + triangleBorderHeight, centerY - halfRadiusBorder);
this.hexagonBorderPath.lineTo(centerX + triangleBorderHeight, centerY + halfRadiusBorder);
this.hexagonBorderPath.close();
invalidate();
}
@Override
public void onDraw(Canvas c) {
c.drawPath(hexagonBorderPath, mBorderPaint);
c.clipPath(hexagonPath, Region.Op.INTERSECT);
c.drawColor(Color.TRANSPARENT, PorterDuff.Mode.CLEAR);
super.onDraw(c);
}
@Override
public void onMeasure(int widthMeasureSpec, int heightMeasureSpec){
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
int width = MeasureSpec.getSize(widthMeasureSpec);
int height = MeasureSpec.getSize(heightMeasureSpec);
setMeasuredDimension(width, height);
calculatePath(Math.min(width/2f, height/2f) - 10f);
}
}
在XML
<YourpakageName.HexagonMaskView
android:id="@+id/image"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:src="@drawable/bear"
android:background="@android:color/holo_green_light"/>

雅他可以使用列表子認爲圖像視圖,並添加一些邊際(正面和負面)基於偶數位置 – Redman

嘿使用矢量圖像爲: -
<vector android:height="24dp"
android:viewportHeight="628.0"
android:viewportWidth="726.0"
android:width="27dp"
xmlns:android="http://schemas.android.com/apk/res/android">
<path
android:fillColor="#00ffffff"
android:pathData="m723,314c-60,103.9 -120,207.8 -180,311.8 -120,0 -240,0 -360,0C123,521.8 63,417.9 3,314 63,210.1 123,106.2 183,2.2c120,0 240,0 360,0C603,106.2 663,210.1 723,314Z"
android:strokeColor="#000000"
android:strokeWidth="4" />
希望這help.Happy編碼。
請參考[這裏](http://stackoverflow.com /問題/ 8840729/Android的六邊形網格)。也許這將幫助你 –
