我想讀取存儲在使用PDFViewer.jar
資源文件夾的PDF文件夾資產閱讀PDF,使用PDFViewer.jar
我想這樣,但我得到錯誤信息,它就會停止不幸。
任何人都可以幫助我如何實現它。
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
CopyReadAssets();
}
private void CopyReadAssets() {
AssetManager assetManager = getAssets();
InputStream in = null;
OutputStream out = null;
File file = new File(getFilesDir(), "ABC.pdf");
try {
in = assetManager.open("ABC.pdf");
out = openFileOutput(file.getName(), Context.MODE_WORLD_READABLE);
copyFile(in, out);
in.close();
in = null;
out.flush();
out.close();
out = null;
} catch (Exception e) {
Log.e("tag", e.getMessage());
}
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(
Uri.parse("file://" + getFilesDir() + "/ABC.pdf"),
"application/pdf");
startActivity(intent);
}
private void copyFile(InputStream in, OutputStream out) throws IOException {
byte[] buffer = new byte[1024];
int read;
while ((read = in.read(buffer)) != -1) {
out.write(buffer, 0, read);
}
}
}
