如何在 Android 中使用外部應用程序打開文檔 pdf/docx

Answer 1

試試下面的代碼：

 File pdfFile = new File("File Path");
 Intent openPdf = new Intent(Intent.ACTION_VIEW);
 openPdf.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
 fileUri = FileProvider.getUriForFile(viewContext,com.mydomain.fileprovider, pdfFile);
 openPdf.setDataAndType(fileUri, "application/pdf");
 openPdf.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
 startActivity(Intent.createChooser(openPdf, "Select Application"));

注意：您需要 File Provider 來授予 URI 權限檢查這個

Answer 2

這將幫助你

//method to show file chooser
    private void showFileChooser() {
        Intent intent = new Intent();
        intent.setType("application/pdf");
        intent.setAction(Intent.ACTION_GET_CONTENT);
        startActivityForResult(Intent.createChooser(intent, "Select Pdf"), PICK_PDF_REQUEST);
    }

您將在 onActivity 結果中得到結果

//handling the image chooser activity result
    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        if (requestCode == PICK_PDF_REQUEST && resultCode == RESULT_OK && data != null && data.getData() != null) {
            filePath = data.getData();
        }
    }
