Textview 文本旋轉，傾斜，textview傾斜

Textview 文本旋轉，傾斜，textview傾斜
有時候Android內建的控制項無法滿足我們的某些要求，這時就需要我們自訂控制項來實現這些功能。比如需要一個TextView裡的字傾斜一定的角度，就需要自訂TextView。

代碼如下：

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();}@Overrideprotected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {super.onMeasure(widthMeasureSpec, heightMeasureSpec);setMeasuredDimension(getMeasuredWidth(), getMeasuredWidth());}@Overrideprotected 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：

<declare-styleable name="RotateTextView">        <attr name="degree" format="dimension" />    </declare-styleable>

用法：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical" >    <com.android.textviewrotatedemo.RotateTextView        android:id="@+id/ceshi"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:autoLink="all"        android:gravity="center"        android:layout_gravity="center"        android:text="http://blog.csdn.net/u014649598" />    <com.android.textviewrotatedemo.RotateTextView        android:id="@+id/ceshi1"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:autoLink="all"        android:gravity="center"        android:layout_gravity="center"        android:text="測試測試測試" />    <com.android.textviewrotatedemo.RotateTextView        android:id="@+id/ceshi2"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:autoLink="all"        android:gravity="center"        android:layout_gravity="center"        android:text="測試測試測試" />    <com.android.textviewrotatedemo.RotateTextView        android:id="@+id/ceshi3"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:autoLink="all"        android:gravity="center"        android:layout_gravity="center"        android:text="測試測試測試4" />    <com.android.textviewrotatedemo.RotateTextView        android:id="@+id/ceshi4"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:autoLink="all"        android:gravity="center"        android:layout_gravity="center"        android:text="測試測試測試" /></LinearLayout>

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;@Overrideprotected 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);}}
