import android.app.AlertDialog;
import android.content.DialogInterface;
import import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;

public class MainActivity extends AppCompatActivity {

    private Button showDialogButton;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        showDialogButton = findViewById(R.id.show_dialog_button);
        showDialogButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                showInputDialog();
            }
        });
    }

    private void showInputDialog() {
        AlertDialog.Builder builder = new AlertDialog.Builder(this);

        final EditText inputEditText = new EditText(this);
        builder.setView(inputEditText);

        builder.setPositiveButton("确定", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                String inputText = inputEditText.getText().toString();
                // 处理输入内容
            }
        });

        builder.setNegativeButton("取消", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                dialog.cancel();
            }
        });

        AlertDialog dialog = builder.create();
        dialog.show();
    }
}
