AlertDialog不适用(The AlertDialog does not apper)

我有一个TO-DO List，并且有一个AlertDialog可以将项目添加到ListView。 在每个项目上有一个Button（id：button1），当我点击Button想要一个AlertDialog来apper。 我尝试了不同的代码，但我无法弄清楚如何做到这一点。

这是我的代码......

button1 = (Button) findViewById(R.id.button1); dialog = new AlertDialog.Builder(MainActivity.this).create(); dialog.setMessage("New list name"); dialog.setButton("Rename", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { dialog.cancel(); } }); dialog.setButton2("Delete", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { dialog.dismiss(); } }); dialog.setButton3("Cancel", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { dialog.cancel(); } }); button1.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { dialog.show(); } });

所以我想要更多的Button来显示AlertDialog。

请帮忙。

你正试图在listitem中实现一个可点击的按钮wiah也是一个可点击的区域，android与它混淆，请阅读这个很好的教程;）

另一方面，如果单击按钮，问题实际上是显示对话框，请确保调用dialog.show（）; 最后 ;）

You are trying to implement a clickable button inside a listitem wiah is also a clickable area, android gets confused with it, please read this nice tutorial ;)

If, on the other hand the button is getting clicked, and the problem is actually in showing the dialog please make sure that you call dialog.show(); at the end ;)
