文本操作类SpannableString的使用

今天来看下textview到底有多强，直接上代码：

布局的话很简单，就是垂直线性布局里面放了9个textview，这里我就不放出来了

public classMainActivityextendsAppCompatActivity {

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

TextView textView = (TextView) findViewById(R.id.tv1);

TextView textView2 = (TextView) findViewById(R.id.tv2);

TextView textView3 = (TextView) findViewById(R.id.tv3);

TextView textView4 = (TextView) findViewById(R.id.tv4);

TextView textView5 = (TextView) findViewById(R.id.tv5);

TextView textView6 = (TextView) findViewById(R.id.tv6);

TextView textView7 = (TextView) findViewById(R.id.tv7);

TextView textView8 = (TextView) findViewById(R.id.tv8);

TextView textView9 = (TextView) findViewById(R.id.tv9);

TextView textView10 = (TextView) findViewById(R.id.tv10);

//分别设置颜色

SpannableString spannableString = newSpannableString("lebron james");

spannableString.setSpan(newForegroundColorSpan(Color.RED),0,6,Spanned.SPAN_INCLUSIVE_EXCLUSIVE);

spannableString.setSpan(newForegroundColorSpan(Color.BLUE),7,12,Spanned.SPAN_EXCLUSIVE_INCLUSIVE);

textView.append(spannableString);

//分别设置点击事件

SpannableString spannableString1 = newSpannableString("kobe james");

spannableString1.setSpan(newClickableSpan() {

@Override

public void onClick(View widget) {

Toast.makeText(MainActivity.this,"kobe",Toast.LENGTH_SHORT).show();

}

},0,4,Spanned.SPAN_INCLUSIVE_EXCLUSIVE);

spannableString1.setSpan(newClickableSpan() {

@Override

public void onClick(View widget) {

Toast.makeText(MainActivity.this,"james",Toast.LENGTH_SHORT).show();

}

},5,10,Spanned.SPAN_INCLUSIVE_EXCLUSIVE);

textView2.append(spannableString1);

//设置textview可点击

textView2.setMovementMethod(LinkMovementMethod.getInstance());

//分别设置URL

SpannableString spannableString2 = newSpannableString("百度,网易");

spannableString2.setSpan(newURLSpan("http://www.baidu.com"),0,2,Spanned.SPAN_EXCLUSIVE_INCLUSIVE);

spannableString2.setSpan(newURLSpan("http://www.baidu.com"),3,spannableString2.length(),Spanned.SPAN_EXCLUSIVE_INCLUSIVE);

textView3.append(spannableString2);

//设置textview可点击

textView3.setMovementMethod(LinkMovementMethod.getInstance());

//设置删除线

SpannableString spannableString3 = newSpannableString("删除线");

spannableString3.setSpan(newStrikethroughSpan(),0,spannableString3.length(),Spanned.SPAN_EXCLUSIVE_INCLUSIVE);

textView4.append(spannableString3);

//设置下标

SpannableString spannableString4 = newSpannableString("(x1+x2)2=x12+x22+2*x1x2");

spannableString4.setSpan(newSubscriptSpan(),2,3,Spanned.SPAN_EXCLUSIVE_INCLUSIVE);

spannableString4.setSpan(newSubscriptSpan(),5,6,Spanned.SPAN_EXCLUSIVE_INCLUSIVE);

spannableString4.setSpan(newSubscriptSpan(),10,11,Spanned.SPAN_EXCLUSIVE_INCLUSIVE);

spannableString4.setSpan(newSubscriptSpan(),14,15,Spanned.SPAN_EXCLUSIVE_INCLUSIVE);

spannableString4.setSpan(newSubscriptSpan(),20,21,Spanned.SPAN_EXCLUSIVE_INCLUSIVE);

spannableString4.setSpan(newSubscriptSpan(),22,23,Spanned.SPAN_EXCLUSIVE_INCLUSIVE);

//设置上标

spannableString4.setSpan(newSuperscriptSpan(),7,8,Spanned.SPAN_EXCLUSIVE_INCLUSIVE);

spannableString4.setSpan(newSuperscriptSpan(),11,12,Spanned.SPAN_EXCLUSIVE_INCLUSIVE);

spannableString4.setSpan(newSuperscriptSpan(),15,16,Spanned.SPAN_EXCLUSIVE_INCLUSIVE);

textView5.append(spannableString4);

//设置下滑线

SpannableString spannableString5 = newSpannableString("下划线");

spannableString5.setSpan(newUnderlineSpan(),0,spannableString5.length(),Spanned.SPAN_EXCLUSIVE_INCLUSIVE);

textView6.append(spannableString5);

//设置基于X轴的缩放

SpannableString spannableString6 = newSpannableString("基于X轴的缩放");

spannableString6.setSpan(newScaleXSpan(4),0,spannableString6.length(),Spanned.SPAN_EXCLUSIVE_INCLUSIVE);

textView7.append(spannableString6);

//设置各种点击事件

SpannableString spannableString7 = newSpannableString("打电话,发短信,发邮件,上网");

spannableString7.setSpan(newURLSpan("tel:[phone]"),0,3,Spanned.SPAN_EXCLUSIVE_INCLUSIVE);

spannableString7.setSpan(newURLSpan("smsto:13515135666"),4,7,Spanned.SPAN_EXCLUSIVE_INCLUSIVE);

spannableString7.setSpan(newURLSpan("mailto:[e-mail]"),8,11,Spanned.SPAN_EXCLUSIVE_INCLUSIVE);

spannableString7.setSpan(newURLSpan("http://lol.qq.com/"),12,spannableString7.length(),Spanned.SPAN_EXCLUSIVE_INCLUSIVE);

textView8.append(spannableString7);

textView8.setMovementMethod(LinkMovementMethod.getInstance());

//设置图片

SpannableString spannableString8 = newSpannableString("这是一张图片哈哈哈");

spannableString8.setSpan(newDynamicDrawableSpan() {

@Override

publicDrawablegetDrawable() {

Drawable drawable = getResources().getDrawable(R.mipmap.ic_launcher);

drawable.setBounds(0,0,100,100);

returndrawable;

}

},5,spannableString8.length(),Spanned.SPAN_EXCLUSIVE_INCLUSIVE);

textView9.append(spannableString8);

}

}
