由于項(xiàng)目開(kāi)發(fā)需要，需要了一個(gè)查看在線PDF的功能，寫(xiě)下這個(gè)測(cè)試Demo,供以后查閱方便。
1.新建一個(gè)Android項(xiàng)目
2.添加依賴類(lèi) compile 'es.voghdev.pdfviewpager:library:1.0.3'
3.實(shí)現(xiàn)類(lèi)代碼
public classMainActivityextendsAppCompatActivityimplementsDownloadFile.Listener {
privateRemotePDFViewPagerpdfViewPager;
privateEditTexteditText;
privateButtonbutton;
privatePDFPagerAdapteradapter;
@Override
protected voidonCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
initUI();
setDownloadButtonListener();
}
private voidsetDownloadButtonListener() {
finalContext ctx =this;
finalDownloadFile.Listener listener =this;
button.setOnClickListener(newView.OnClickListener() {
@Override
public voidonClick(View v) {
pdfViewPager=newRemotePDFViewPager(ctx,editText.getText().toString().trim(),listener);
pdfViewPager.setId(R.id.pdf_view);
hideDownloadButton();
}
});
}
private voidinitUI() {
editText= (EditText) findViewById(R.id.urlEdit);
button= (Button) findViewById(R.id.openUrlBtn);
}
@Override
public voidonSuccess(String url,String destinationPath) {
adapter=newPDFPagerAdapter(this,FileUtil.extractFileNameFromURL(url));
pdfViewPager.setAdapter(adapter);
showDownloadButton();
setContentView(pdfViewPager);
}
@Override
public voidonFailure(Exception e) {
e.printStackTrace();
showDownloadButton();
Toast.makeText(this,"下載失敗",Toast.LENGTH_SHORT).show();
}
@Override
public voidonProgressUpdate(intprogress, inttotal) {
}
public voidshowDownloadButton() {
button.setVisibility(View.VISIBLE);
}
public voidhideDownloadButton() {
button.setVisibility(View.INVISIBLE);
}
@Override
protected voidonDestroy() {
super.onDestroy();
if(adapter!=null) {
adapter.close();
}
}
}
4.添加權(quán)限 網(wǎng)絡(luò)、讀取存儲(chǔ)、寫(xiě)存儲(chǔ)的權(quán)限
5.當(dāng)然還有其他是使用方法，具體參考地址：https://github.com/voghDev/PdfViewPager?
