我在设置警报下部的两个按钮时遇到了麻烦，我想做的是获得与 IOS 按钮外观类似的外观。这是我当前的代码：public void openInstructions() { AlertDialog.Builder builder = new AlertDialog.Builder(getActivity()); final AlertDialog dialog = builder.setNegativeButton("OK", new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int id) { setNewDateOnView(); dialog.cancel(); } }).setPositiveButton("CANCEL", new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int id) { dialog.cancel(); } }).create(); TextView myMsg = new TextView(getActivity()); myMsg.setText("ExampleText "); myMsg.setTextSize(15); myMsg.setGravity(Gravity.CENTER_HORIZONTAL); dialog.setView(myMsg); dialog.setTitle("Confirm Date of Purchase"); dialog.setOnShowListener( new DialogInterface.OnShowListener() { @Override public void onShow(DialogInterface arg0) { Button negativeButton = dialog.getButton(AlertDialog.BUTTON_NEGATIVE); negativeButton.setTextColor(0xFFFF0000); Button positiveButton = dialog.getButton(AlertDialog.BUTTON_POSITIVE); positiveButton.setTextColor(0xFF0000FF); } }); dialog.show();}它现在的样子的例子：我想要它的样子：

要像 ios 一样设计 Dialog，我们可以使用自定义布局创建自定义对话框，如下所示：
对话框_自定义.xml

好吧，作为开始，谷歌建议您在创建 Android 应用程序时使用Android 设计指南，实际上您应该坚持这些，因为这是您的用户将习惯的（而不是 Apple 的）。
TextView如果您所做的只是显示文本，也没有理由为对话框分配 a ， setMessageAlertDialog提供了此功能。
如果这还不能说服您遵守正常的设计规则，唯一的其他选择是创建一个自定义视图并将其分配给AlertDialogwith setView（类似于您使用 的方式TextView）。

使用 .setNeutralButton 使位置最左边
TextView 文本视图；按钮按钮；
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
button =(Button)findViewById(R.id.button1);
textview = (TextView)findViewById(R.id.textView1);
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
new AlertDialog.Builder(MainActivity.this).setIcon(R.drawable.ic_launcher_background)
.setTitle("Alert Dialog Box Title")
.setMessage("Are you sure( Alert Dialog Message )")
.setPositiveButton("YES", new DialogInterface.OnClickListener()
{
@Override
public void onClick(DialogInterface dialog, int which)
{
Toast.makeText(MainActivity.this, "You Clicked on Yes", Toast.LENGTH_SHORT).show();
}
})
.setNegativeButton("Cancel", new DialogInterface.OnClickListener()
{
@Override
public void onClick(DialogInterface dialog, int which)
{
Toast.makeText(MainActivity.this, "You Clicked on Cancel", Toast.LENGTH_SHORT).show();
}
})
.setNeutralButton("NO", new DialogInterface.OnClickListener()
{
@Override
public void onClick(DialogInterface dialog, int which)
{
Toast.makeText(MainActivity.this, "You Clicked on NO", Toast.LENGTH_SHORT).show();
}
})
.show();
}
});
}

您可以创建一个自定义视图，例如发送的视图并对其进行扩充
例子：
AlertDialog.Builder mBuilder = new AlertDialog.Builder(getActivity());
View mView=getActivity().getLayoutInflater().inflate(R.layout.custom_layout, null);
mBuilder.setView(mView);
Button close = (Button) mView.findViewById(R.id.close);
Button OK = (Button) mView.findViewById(R.id.ok);
close.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
//close the dialog
hideDialog1();
}
});
OK.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
//do something
}
});
dialog = mBuilder.create();
dialog.setCanceledOnTouchOutside(false);
dialog.show();
