Android中Dialog的使用

图一（提示对话框）图二（列表）

图三（多选）图四（单选）

图一代码为showDialog1,图二为dialog2,图三为dialog3……

如何将自定义文件布局设置到弹出框中：

//实例化布局文件

final View view =getLayoutInflater().inflate(R.layout.land_layout,null);
builder5.setView(view)

上述代码完整模式

LayoutInflaterinflater = LayoutInflater.from(this);

View view =inflater.inflate(R.layout.radio_child);

builder5.setView(view)

代码区：

public void showDialog1(View v){
//创建一个提示对话框的构构造者
AlertDialog.Builderbuilder = newAlertDialog.Builder(this);
builder.setTitle("FirstDialog");
builder.setMessage("setMessage");
builder.setIcon(android.R.drawable.ic_dialog_alert);
builder.setPositiveButton("OK",new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
Toast.makeText(MainActivity.this,"GOGO",Toast.LENGTH_SHORT).show();
}
});
builder.setNegativeButton("NO",new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
Toast.makeText(MainActivity.this,"COMEBABY",Toast.LENGTH_SHORT).show();
}
});
builder.setNeutralButton("MID",new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
Toast.makeText(MainActivity.this,"I'mneutral",Toast.LENGTH_SHORT).show();
}
});
// AlertDialog dialog =builder.create();
//dialog.show();
builder.show();
}
public void dialog2(View v){
