自定義textview實(shí)現(xiàn)整齊排版

android開發(fā)中的textview可以自動(dòng)換行,但是對(duì)于顯示純英文文字來(lái)說很好版參差不齊，超級(jí)難看，這就需要重寫textviewTextView在顯示中文的時(shí)候遵循以下規(guī)則：一、重寫TextView算法的原對(duì)此TextViewcanvas.drawText(str,x,y,mPaint)方法進(jìn)這里要說明自己命名的幾種標(biāo)點(diǎn)名稱：二、相關(guān)代碼onDrawonDraw首先，通過Canvascanvas){if(tempLineArray==null||canvas==null||mTextStr==}for(intlineNum=0;lineNum<tempLineArray.size();lineNum++){LineParlinePar=tempLineArray.get(lineNum);intstart=intend=floatwidth=intlineCountlinePar.getLineCountif(lineNum>0&&lineNum==tempLineArray.size()-1)/**之前獲取到實(shí)際文本長(zhǎng)度后，無(wú)法將其值設(shè)置為TEXTVIEW高度**/mBaikeTextHeight=((lineCount)*(mLineSpace+mTextSize));}floatlineWidth=for(intstrNum=start;strNum<=end;strNum++)Stringstr=null;if(ch=='\n'){str="";}elsestr=}if(str==null||str.equals("")==true)}if(strNum>=start&&strNum<=end&&lineCount>=1){(mFontHeight-mOffset)+(lineCount-(mLineSpace-2),lineWidth=lineWidth-width;}}}}}TEXTVIEW后將其高度賦值給自定義的TEXTVIEW，賦值結(jié)束后，關(guān)閉線程。privateHandlerhandler=newHandler()publicvoidhandleMessage(Messagemsg)if(msg!=null){b= paint_end=Log.d("textView:",""+}}classheightimplementsRunnablepublicvoidrun()while(b)try}catch(InterruptedExceptione1){}try//當(dāng)繪制TEXTVIEWif(paint_end==true&&mBaikeTextHeight!=0){Log.d("height",""+mBaikeTextHeight);//if(mBaikeTextHeight>mScreenHeight){Messagemsg=handler.obtainMessage();msg.what=0;}catch(Exceptione)Log.d("height","error:"+}}}}如果需要將其工具化，可以在XML文件里設(shè)置textview的行距，然后在if(lineNum>0&&lineNum==tempLineArray.size()-1)/**之前獲取到
