Question

虽然在这个论坛上有很多这个问题的例子，但我仍然无法找到合适的地方开始新的活动。

继承我的代码：

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.screen1);

    final EditText milein = (EditText) findViewById(R.id.milein);
    final EditText zipin = (EditText) findViewById(R.id.zipin);
    final EditText mileout = (EditText) findViewById(R.id.mileout);
    final EditText zipout = (EditText) findViewById(R.id.zipout);
    final ToggleButton checkinbutton = (ToggleButton) findViewById(R.id.checkinbutton);
    final Button submit = (Button) findViewById(R.id.submit);

    /** Boolean for Sharedpreferences */
    final SharedPreferences preferences = getPreferences(MODE_PRIVATE);
    boolean tgpref = preferences.getBoolean("tgpref", false);
    checkinbutton.setChecked(tgpref);

    /** ToggleButton Check-IN */
    checkinbutton.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {

            if (checkinbutton.isChecked()) {
                milein.setVisibility(View.VISIBLE);
                zipin.setVisibility(View.VISIBLE);
                mileout.setVisibility(View.GONE);
                zipout.setVisibility(View.GONE);
                submit.setVisibility(View.VISIBLE);
                SharedPreferences.Editor editor = preferences.edit();
                /**
                 * <-- Boolean Preferences for Checkinbutton ToggleButton
                 * Checked
                 */
                editor.putBoolean("tgpref", true);
                editor.commit();

            } else {

                milein.setVisibility(View.GONE);
                zipin.setVisibility(View.GONE);
                mileout.setVisibility(View.VISIBLE);
                zipout.setVisibility(View.VISIBLE);
                submit.setVisibility(View.VISIBLE);
                SharedPreferences.Editor editor = preferences.edit();
                /**
                 * <-- Boolean Preferences for Checkinbutton ToggleButton
                 * UnChecked
                 */
                editor.putBoolean("tgpref", false);
                editor.commit();

                /** AlertDialog Button Configurations */

                final AlertDialog alertDialog = new AlertDialog.Builder(
                        screen1.this).create();
                alertDialog.setMessage("Check-Out?");
                alertDialog.setButton("Yes",
                        new DialogInterface.OnClickListener() {
                            public void onClick(DialogInterface dialog,
                                    int which) {
                            }

                        });
                alertDialog.setButton2("No",
                        new DialogInterface.OnClickListener() {
                            public void onClick(DialogInterface dialog,
                                    int which) {
                                checkinbutton.setChecked(true);
                                milein.setVisibility(View.VISIBLE);
                                zipin.setVisibility(View.VISIBLE);
                                mileout.setVisibility(View.GONE);
                                zipout.setVisibility(View.GONE);
                            }
                        });
                alertDialog.show();
            }
        };
    });
}


public void onClick(View v) {

    }

}

我试图在任何地方实施新的屏幕活动，但仍然无法得到它。任何有关建议应该去哪里的帮助都会非常感激。

感谢。

我猜你想在onClick方法结束时更改活动。实际上，您希望在onClick方法的每个条件的末尾包含两个，一个。

在条件结束时，只需添加以下代码：

startActivity(new Intent(CurrentActivity.this, NewActivity.class));
CurrentActivity.this.finish();

另外，请确保将新活动添加到Manifest文件中：

<activity
    android:name=".NewActivity"
    android:label="@string/newActivityTitle" >
</activity>

一旦您的代码到达每个条件的末尾，如果新活动设置正确，则新活动应该接管。
