这＆＃34;代码A＆＃34;是我的基类的代码，我将这个类扩展到另一个类＆＃34;代码B＆＃34;。问题是，当我运行我的应用程序时，我的应用程序已停止。我的Base类有什么问题，或者我没有正确调用它们？活动已在清单文件中注册。
代码A
public class PrepaidBase extends Activity {
PrepaidBase pb = new PrepaidBase();
private String number = "";
public void alertDialogShow(Context context, String title, String message, String _number) {
this.number = _number;
AlertDialog.Builder builder = new AlertDialog.Builder(context);
builder.setTitle(title);
builder.setMessage(message);
builder.setCancelable(false);
builder.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
call();
}
});
builder.setNegativeButton("No", new DialogInterface.OnClickListener()
{
@Override
public void onClick(DialogInterface dialog, int which)
{
dialog.cancel();
}
});
}
public void call()
{
Intent in = new Intent(Intent.ACTION_CALL, Uri.parse("tel:" + Uri.encode(number)));
try
{
startActivity(in);
}catch (ActivityNotFoundException e)
{
e.printStackTrace();
}
}
代码B
public class PrepaidLBO extends PrepaidBase {
Button chobeesButton;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.chobeesghantay);
chobeesButton = (Button)findViewById(R.id.chobeesButton);
pb.alertDialogShow(PrepaidLBO.this, "Some Test" , "Text Here too" , "*1234#");
chobeesButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
call();
}
});

您也可以像这样实现BASE类
public class PrepaidBase extends Activity {
AlertDialog.Builder builder;
private String number = "";
private String packageName;
private String price;
private String title;
public PrepaidBase()
{}
public void setPackageInformation(String name, String price, String number, String title)
{
this.number = number;
this.packageName = name;
this.price = price;
this.title = title;
}
public void activatePackage()
{
try
{
new AlertDialog.Builder(PrepaidBase.this)
.setTitle(PrepaidBase.this.title)
.setMessage("Are you sure you want to activate " + PrepaidBase.this.packageName + " in RS: " + PrepaidBase.this.price)
.setPositiveButton(android.R.string.yes, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
Intent in = new Intent(Intent.ACTION_CALL, Uri.parse("tel:" + Uri.encode(PrepaidBase.this.number)));
startActivity(in);
}
})
.setNegativeButton(android.R.string.no, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
dialog.cancel();
}
})
//.setIcon(android.R.drawable.ic_dialog_alert)
.show();
}catch (ActivityNotFoundException e)
{
e.printStackTrace();
}
}
和你从BASE继承的其他CHILD类</ p>
public class PrepaidLBO extends PrepaidBase implements View.OnClickListener {
Button chobeesButton;
public PrepaidLBO()
{
setPackageInformation("Package Name", "Your Price", "*123#", "Your Title");
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.chobeesghantay);
chobeesButton = (Button) findViewById(R.id.chobeesButton);
chobeesButton.setOnClickListener(this);
}
@Override
public void onClick(View v)
{
activatePackage();
}

您正在递归创建大量实例
你的问题是这行 PrepaidBase pb = new PrepaidBase（）; ，它位于 PrepaidBase 活动内。
这意味着每次创建PrepaidBase实例时，它都会创建自己的另一个实例，直到达到内存限制，并且GC启动。
