Question

我需要能够将文本发送到whatsapp联系人，堆栈溢出似乎一致同意这是有效的：

path.join()

如果.setType（“text / plain”）;被注释掉了，它只是打开了我给它的数字聊天的whatsapp，但如果我不评论它，没有任何事情发生，任何帮助表示赞赏。

Answer 1

更改并添加最后一行删除sendIntent.setType的评论

Uri uri = Uri.parse("smsto:" + "<number>"); 
Intent sendIntent = new Intent(Intent.ACTION_SENDTO, uri);
sendIntent.putExtra(Intent.EXTRA_TEXT, "YOOOH");
sendIntent.setType("text/plain");

// this line helps to open the chooser dialog
startActivity(Intent.createChooser(sendIntent, getResources().getString(R.string.share)));

请查看此代码段，如果未安装用户，还会处理该案例 WHATSAPP。

PackageManager pm=getPackageManager();
                try {
                    Intent intent = new Intent(Intent.ACTION_SEND);
                    intent.setType("text/plain");
                    String text = "YOUR TEXT HERE";
                    PackageInfo info=pm.getPackageInfo("com.whatsapp", PackageManager.GET_META_DATA);
                    //Check if package exists or not. If not then code
                    //in catch block will be called
                    intent.setPackage("com.whatsapp");
                    intent.putExtra(Intent.EXTRA_TEXT, text);
                    startActivity(Intent.createChooser(intent, "Share with"));

                } catch (PackageManager.NameNotFoundException e) {
                    Toast.makeText(MainActivity.this, "WhatsApp not Installed", Toast.LENGTH_SHORT)
                            .show();
                }

Android内容通过Intent无法正常工作，
