Textview 文本旋转，倾斜

有时候Android自带的控件无法满足我们的某些要求，这时就需要我们自定义控件来实现这些功能。比如需要一个TextView里的字倾斜一定的角度，就需要自定义TextView。

代码如下：

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49

package com.android.textviewrotatedemo;   import android.content.Context; import android.content.res.TypedArray; import android.graphics.Canvas; import android.util.AttributeSet; import android.view.Gravity; import android.widget.TextView;   /**  * Created by zhenxixianzai on 2015/5/5.  */ public class RotateTextView extends TextView {     private static final int DEFAULT_DEGREES = 0;     private int mDegrees;       public RotateTextView(Context context) {         super(context, null);     }       public RotateTextView(Context context, AttributeSet attrs) {         super(context, attrs, android.R.attr.textViewStyle);         this.setGravity(Gravity.CENTER);         TypedArray a = context.obtainStyledAttributes(attrs,                 R.styleable.RotateTextView);         mDegrees = a.getDimensionPixelSize(R.styleable.RotateTextView_degree,                 DEFAULT_DEGREES);         a.recycle();     }       @Override     protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {         super.onMeasure(widthMeasureSpec, heightMeasureSpec);         setMeasuredDimension(getMeasuredWidth(), getMeasuredWidth());     }       @Override     protected void onDraw(Canvas canvas) {         canvas.save();         canvas.translate(getCompoundPaddingLeft(), getExtendedPaddingTop());         canvas.rotate(mDegrees, this.getWidth() / 2f, this.getHeight() / 2f);         super.onDraw(canvas);         canvas.restore();     }       public void setDegrees(int degrees) {         mDegrees = degrees;     } }

styles 如下：

?

1 2 3

<declare-styleable name="RotateTextView">               </attr></declare-styleable>

用法：

Java 部分：

package com.android.textviewrotatedemo;   import android.app.Activity; import android.os.Bundle;   public class MainActivity extends Activity {     private RotateTextView mTextView;     private RotateTextView mTextView1;     private RotateTextView mTextView2;     private RotateTextView mTextView3;     private RotateTextView mTextView4;     private RotateTextView mTextView5;       @Override     protected void onCreate(Bundle savedInstanceState) {         super.onCreate(savedInstanceState);         setContentView(R.layout.activity_main);         mTextView = (RotateTextView) findViewById(R.id.ceshi);         mTextView.setDegrees(10);         mTextView1 = (RotateTextView) findViewById(R.id.ceshi1);         mTextView1.setDegrees(350);         mTextView2 = (RotateTextView) findViewById(R.id.ceshi2);         mTextView2.setDegrees(180);         mTextView3 = (RotateTextView) findViewById(R.id.ceshi3);         mTextView3.setDegrees(90);         mTextView4 = (RotateTextView) findViewById(R.id.ceshi4);         mTextView4.setDegrees(290);       } }
