AlertDialog.Builder builder=new AlertDialog.Builder(AlterDialogActivity.this);
builder
.setTitle("对话框")
.setIcon(R.mipmap.ic_launcher_round)
.setPositiveButton("确定",null)
.setNegativeButton("取消",null)
.setMessage("简单对话框")
.create()
.show();
2.列表对话框
AlertDialog.Builder builder=new AlertDialog.Builder(AlterDialogActivity.this);
final String[] mItems={"item0","item1","item2","item3","item4","item5","item6"};
builder.setTitle("列表对话框")
.setItems(mItems, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialogInterface, int i) {
Toast.makeText(AlterDialogActivity.this,mItems[i],Toast.LENGTH_SHORT).show();
}
})
.setPositiveButton("确定",null)
.setNegativeButton("取消",null)
.create()
.show();
3.单选对话框
AlertDialog.Builder builder=new AlertDialog.Builder(AlterDialogActivity.this);
final String[] items={"item1","item2","item3","item4"};
builder.setTitle("单选对话框")
.setIcon(R.mipmap.ic_launcher_round)
.setSingleChoiceItems(items,0,new DialogInterface.OnClickListener(){
@Override
public void onClick(DialogInterface dialogInterface, int i) {
Toast.makeText(AlterDialogActivity.this,items[i]+"被点击了",Toast.LENGTH_SHORT).show();
singleChoise=i;
}
})
.setPositiveButton("确定",null)
.setNegativeButton("取消",null)
.create()
.show();
4.多选对话框
AlertDialog.Builder builder=new AlertDialog.Builder(AlterDialogActivity.this);
final String[] items={"item1","item2","item3","item4"};
builder.setTitle("多选对话框")
.setIcon(R.mipmap.ic_launcher_round)
.setMultiChoiceItems(items,new boolean[]{false,false,false,false},new DialogInterface.OnMultiChoiceClickListener(){
@Override
public void onClick(DialogInterface dialogInterface, int i, boolean b) {
if(b){
Toast.makeText(AlterDialogActivity.this,items[i]+"被选中了",Toast.LENGTH_SHORT).show();
}else{
Toast.makeText(AlterDialogActivity.this,items[i]+"被取消选中",Toast.LENGTH_SHORT).show();
}
}
})
.setPositiveButton("确定",null)
.setNegativeButton("取消",null)
.create()
.show();
5.自定义View对话框
AlertDialog.Builder builder=new AlertDialog.Builder(AlterDialogActivity.this);
View view= LayoutInflater.from(this).inflate(R.layout.alterdialot_img,null);
builder
// .setTitle("自定义对话框")
// .setIcon(R.mipmap.ic_launcher_round)
.setView(view)
.setCancelable(true)
.setNegativeButton("取消",null)
.create()
.show();
